74ABT640
FEATURES
Octal bidirectional bus interface
3-State buffers
Power-up 3-State
Live insertion/extraction permitted
Output capability: +64mA/–32mA
Latch-up protection exceeds 500mA per Jedec Std 17

DESCRIPTION
The 74ABT640 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT640 device is an octal transceiver featuring inverting
3-State bus compatible outputs in both send and receive directions.
The control function implementation minimizes external timing
requirements. The device features an Output Enable (OE) input for
easy cascading and a Direction (DIR) input for direction control.
