KK74AC623 is a high-performance silicon-gate CMOS Octal 3-State Noninverting Bus Transceiver. It is pin-compatible with the LS/ALS623, HC/HCT623. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs. The KK74AC623 is a 3-state noninverting transceiver that is used for 2-way communication between data buses. Two separate enables are available. The enable for bus A to B is active-high, the enable for bus B to A is active-low.
The KK74AC623 is an octal 3‑state non‑inverting bus transceiver designed for two‑way communication between data buses. It features separate enable signals for each direction (A‑to‑B active‑high, B‑to‑A active‑low) and is compatible with CMOS, NMOS, and TTL logic levels.
The device is offered in Plastic DIP and SOIC packages, with detailed electrical characteristics including a 2.0‑6.0 V supply range, 24 mA source/sink output current, and up to 750 mW power dissipation in the DIP package. Pin assignments, logic diagrams, and propagation delay specifications are provided for design integration.
