The 74FCT162240CTPVCT is a 16-bit inverting buffer from the 74FCT series, organized as four independent 4-bit elements with 3-state outputs. The 48-SSOP package (0.295" body width) suits dense PCB layouts where a single 16-bit wide bus interface replaces multiple smaller buffers.
Supply rail and drive — the 5 V decision
It will not run from a 3.3 V or lower rail — if your system has migrated to lower voltages, look at the 2.7V–3.6V 74LVTH family instead. The 24 mA symmetric drive is enough to fan out to multiple CMOS loads or drive a short backplane trace, but not intended for high-current line driving like RS-485 or cable interfaces.
Temperature grade — industrial floor
Not rated for full military or downhole environments, but the range handles most commercial and industrial enclosures without derating.
