16-bit bidirectional transceiver for 5V backplane and memory buses
The 74FCT162245TPV is a 16-bit bidirectional transceiver with non-inverting outputs and 3-state capability, designed for 5V logic systems. It splits into two independent 8-bit elements, each with its own direction and output-enable control, so you can route separate byte lanes on a bus without extra glue logic.
No lab bench needed for a field swap if you have a hot-air station and a steady hand — the pin pitch is tight but the body marking is clear.
No last-time-buy clock ticking, no urgent need to qualify a second source. That said, the RoHS compliance status is listed as non-compliant, so if your assembly line is RoHS-exempt or you have a legacy solder process, this part fits; for full RoHS builds, check your exemption status or look at the lead-free suffix variants in the same family.
