The 74ABT162245A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed. The 74ABT162245A device is a 16-bit transceiver featuring non-inverting 3-State bus compatible outputs in both send and receive directions. The control function implementation minimizes external timing requirements. The device features two Output Enable (1OE, 2OE) inputs for easy cascading and two Direction (1DIR, 2DIR) inputs for direction control.
The document provides a product specification for the Philips 74ABT162245A and 74ABTH162245A integrated circuits. These are high-performance BiCMOS devices designed as 16-bit bidirectional bus transceivers featuring non-inverting 3-State outputs compatible with standard bus protocols.
The datasheet details the electrical characteristics, including propagation delays, input/output voltages, and current ratings under various operating conditions. It also includes pin configurations, logic symbols, function tables, and absolute maximum ratings for both the standard version (74ABT162245A) and the bus-hold variant (74ABTH162245A).
