DESCRIPTION
The ACT244 is an advanced CMOS OCTAL BUS
BUFFER (3-STATE) fabricated with sub-micron
silicon gateand double-layermetal wiring C

MOS
technology. It is ideal for low power applications
mantaining high speed operation similar to
equivalentBipolar Schottky TTL.
G controloutput governs four BUS BUFFERs.
This device is desibned to be used with 3 state
memory address drivers, etc.
The device is designed to interface directly High
Speed CMOS systems with TTL, NMOS and
CMOS output voltagelevels.
All
inputs and
outputs
protectioncircuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
