DESCRIPTION
The 74ABT245 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT245 device is an 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 an Output Enable (OE) input for
easy cascading and a Direction (DIR) input for direction control.
