- High-speed data transmission (vs 74AVC4T245)
Design Notes
Decouple VCCA and VCCB with 0.1 µF ceramic capacitors placed as close to the pins as possible. Additionally, use a 10 µF bulk capacitor on each supply rail if the power source is far from the device. Proper decoupling ensures stable operation and reduces noise-induced errors in high-speed level translation.
Keep the traces between the transceiver and the connected buses as short as possible to minimize signal integrity issues. For high-speed signals (up to 380 Mbps), use controlled impedance traces and avoid vias where possible. The VQFN-16 package has an exposed pad; connect it to the ground plane with multiple vias for thermal and electrical performance.
Ensure that the control pins (1DIR, 2DIR, 1OE, 2OE) are driven by the VCCA domain, not VCCB. If the direction or enable signals change while data is being transmitted, bus contention can occur, leading to excessive current and potential damage. Always stabilize control signals before enabling data transmission.
