DESCRIPTION
The 74ABT244 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT244 device is an octal buffer that is ideal for driving bus
lines. The device features two Output Enables (1OE, 2OE), each
controlling four of the 3-State outputs.
