The 74ABT16240A is a high-performance BiCMOS device which combines low static and dynamic power dissipation with high speed and high output drive. This device is an inverting 16-bit buffer that is ideal for driving bus lines. The device features four Output Enables (1OE, 2OE, 3OE, 4OE), each controlling four of the 3-State outputs. Two options are available, 74ABT16240A which does not have the bus hold feature and 74ABTH16240A which incorporates the bus hold feature.
The 74ABT16240A and 74ABTH16240A are 16‑bit inverting buffer/driver ICs with 3‑State outputs, designed for high‑speed bus line driving. The 74ABTH16240A version adds a bus‑hold feature that eliminates the need for external pull‑up resistors.
Key features include a 16‑bit bus interface, four output‑enable groups, +64 mA/‑32 mA output capability, TTL‑compatible I/O levels, live insertion/extraction, and robust latch‑up and ESD protection. The devices are offered in 48‑lead SSOP and TSSOP packages and operate over a wide temperature range.
