This data sheet provides the features of the 74ABT16501A/74ABTH16501A, which is an 18-bit bidirectional bus transceiver with 3-state buffers, output capability of +64mA/-32mA, TTL input and output switching levels, power-up reset, power-up 3-state, positive edge-triggered clock inputs and so on.
This document is a product specification for the Philips 74ABT16501A and 74ABTH16501A, which are high-performance 18-bit universal bus transceivers designed for bidirectional bus interface applications. These devices utilize high-performance BiCMOS technology to combine low static and dynamic power dissipation with high speed and high output drive capabilities.
