16-bit bus transceiver with 24 mA drive for 5 V backplanes
The 74FCT162245ATPVCT is a 16-bit non-inverting transceiver from the 74FCT series, organized as two 8-bit elements with independent direction and output-enable controls. The 3-state outputs allow multiple devices to share a common bus without contention.
With 24 mA output current in both high and low states, this transceiver can drive heavily loaded parallel buses — think address/data lines on a memory card or peripheral backplane — without external buffers. The symmetric drive simplifies timing analysis for bidirectional paths.
The 74FCT series is a mature logic family; no direct factory replacement has been issued, but the part is widely stocked through independent distribution.
