Description

   The 74ABTH16245B high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.

   The 74ABTH16245B 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.

   Two options are available, 74ABTH16245B which does not have the bus hold feature and the 74ABTH16245B which incorporates the bus hold feature.
