DESCRIPTION

The MB2244 high-performance BiCMOS device combines low

static and dynamic power dissipation with high speed and high

output drive.

The MB2244 device is an 16-bit buffer that is ideal for driving bus

lines. The device features four Output Enables (1OE, 2OE, 3OE,

4OE), each controlling four of the 3-State outputs.
