16-bit bus interface buffer — 5V logic, 48-BSSOP
The 74FCT16244ETPV is a FAST 16-bit non-inverting buffer/line driver from the FCT logic family, organized as four 4-bit elements with independent 3-state output enables.
Each output can source 32mA and sink 64mA, providing enough drive for heavily loaded parallel buses with multiple fan-out. The 3-state outputs allow multiple drivers to share a common bus line without contention when the output enable is deasserted. The 4-bit-per-element organization gives granular control — you can gate individual byte lanes without external logic.
The 5V supply tolerance covers both regulated 5V rails and the upper end of a 3.3V-to-5V level-shifted bus.
