DESCRIPTION

The 74ACT16244 is an advanced high-speed

CMOS 16-BIT BUS BUFFER (3-STATE) fabricat-

ed with sub-micron silicon gate and double-layer

metal wiring C2MOS tecnology.

G output control governs four BUS BUFFERs.

The device is designed to be used with 3-state

memory address drivers, clock drivers, and

bus-oriented receivers and transmitters. The de-

vice can be used as four 4-bit buffers, two 8-bit

buffers, or one 16-bit buffer.The device is de-

signed to interface directly High Speed CMOS

systems with TTL, NMOS and CMOS output volt-

age levels.

All inputs and outputs are equipped with protec-

tion circuits against static discharge, giving them

2KV ESD immunity and transient excess voltage.
