DESCRIPTION

The MB2245 high-performance BiCMOS device combines low static

and dynamic power dissipation with high speed and high output

drive.

The MB2245 device is a 16-bit 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.
