Typical Applications
SN74LVC1G08DBVR is suitable for 6 applications: Signal Gating / Enable Logic, Clock Gating for Low Power, 3.3 V to 5 V Mixed-Voltage Interfacing, Portable and Battery-Powered Electronics, Industrial Control Systems, Communication Interface Glue Logic.
Signal Gating / Enable Logic
The SN74LVC1G08DBVR combines two control signals into a single enable condition, outputting HIGH only when both qualifying signals are active. Its 3.3 ns typical propagation delay at 3.3 V keeps gating latency negligible in control paths, while the 24 mA output drive at 3.3 V directly drives enable pins, LED indicators, or optocoupler inputs without a buffer. The Ioff feature makes it safe in systems where the gate may be powered down while neighboring rails remain live.
Recommended
Clock Gating for Low Power
AND-gating a clock with an enable signal is a classic technique to cut dynamic power in idle blocks. The SN74LVC1G08's low 10 uA maximum ICC and fast, consistent tpd minimize both static and timing overhead in the gated clock path. Designers should route the enable signal synchronously (or use register-based gating) to avoid runt pulses; the LVC input structure's 5.5 V tolerance also lets it sit at a 5 V domain boundary in mixed-voltage clock trees.
Recommended
3.3 V to 5 V Mixed-Voltage Interfacing
With a 1.65 V to 5.5 V supply range and inputs tolerating 5.5 V regardless of VCC, the SN74LVC1G08 bridges 3.3 V and 5 V logic domains. Powered at 5 V, it accepts 3.3 V inputs (VIH is low enough per LVC specifications) and outputs full 5 V logic levels with robust 24 mA drive - ideal for driving legacy 5 V peripherals, relays, or indicators from a 3.3 V MCU. The SOT-23-5 footprint fits tight board areas near connectors.
Recommended
Portable and Battery-Powered Electronics
Battery products benefit from the gate's 10 uA maximum ICC, wide 1.65 V to 5.5 V operation across a discharging battery, and tiny SOT-23-5 footprint of about 2.9 mm x 1.6 mm. The Ioff partial-power-down support lets sections of the system sleep while this gate's inputs stay driven, preventing battery drain through backpower paths. For even lower power, the same-footprint SN74AUP1G08DBVR offers the AUP ultra-low-power alternative.
Recommended
Industrial Control Systems
Specified from -40C to +125C, the SN74LVC1G08DBVR handles industrial ambient extremes in PLC I/O gating, interlock logic, and safety-enable chains. The CMOS structure provides high noise immunity against factory-floor transients, and TI's controlled baseline (one assembly/test site, one fab site) supports consistent long-term sourcing. For automotive-adjacent industrial designs requiring AEC-Q100, the SN74LVC1G08QDBVRQ1 is a drop-in qualified variant.
Recommended
Communication Interface Glue Logic
In UART, CAN, and I2C front ends, the SN74LVC1G08 gates transmit-enable signals and combines fault flags before they reach transceivers. Its 3.3 ns tpd adds negligible latency to MHz-class control signals, and 5.5 V-tolerant inputs allow safe connection to 5 V status lines. The DBV package fits near connector edges on dense interface boards; place a 0.1 uF decoupling capacitor within 2 mm of the VCC pin for clean switching.

Key Differentiators
- 5.5 V input tolerance independent of VCC (vs SN74AUP1G08DBVR)
- Higher output drive at 3.3 V (vs SN74AUP1G08DBVR)
- Automotive drop-in option (vs SN74LVC1G08QDBVRQ1)
- Ioff partial-power-down protection (vs SN74AHC1G08DBVR)
Design Notes
Place a 0.1 uF ceramic decoupling capacitor within 2 mm of the VCC pin (pin 5) with a short return to GND (pin 3). The LVC CMOS output draws dynamic shoot-through current during transitions; without local decoupling, fast edges couple into adjacent signals. Per TI datasheet application guidance, a solid ground connection under the SOT-23-5 footprint is sufficient for thermal and EMI performance at this power level.
Never leave inputs A or B floating. CMOS inputs without a defined level can hover near the switching threshold, causing oscillation, excessive ICC, and unpredictable outputs. Tie unused logic to GND (for AND, unused input to GND forces output LOW - use VCC if HIGH is required). Also remember the AND function Y = A AND B: if inversion is needed at either input, pair with SN74LVC1G14DBVR inverter or choose a NAND part.
Leverage the Ioff feature in multi-rail systems: the SN74LVC1G08 tolerates inputs up to 5.5 V while VCC is at 0 V without drawing damaging backflow current. However, note that output Y is high-impedance when powered down - downstream circuitry must not depend on a defined output level during partial power-down. Sequence-sensitive loads may need a pull-down resistor on Y.
With 3.3 ns typical tpd and 24 mA drive, this gate can drive traces up to roughly 5-10 cm without series termination at 3.3 V. For longer traces or heavily loaded buses, add a 22-33 ohm series resistor near the output to damp reflections, or buffer with SN74LVC2G34DCKR. Keep stub lengths short when gating clock signals to minimize runt-pulse risk.
