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.
