74ABT16245B
16-bit bus transceiver; 3-state
Rev. 4 — 19 August 2014
Product data sheet
1. General description
The 74ABT16245B high-performance BiCMOS device combines low static and dynamic
power dissipation with high speed and high output drive.
The 74ABT16245B device is a dual octal 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 input and output voltage ratings may be exceeded if the input and output current ratings are observed.
The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability.
