Quiet Series Octal Buffer/Line Driver with TRI-STATE
Outputs
General Description
The ’ACQ/’ACTQ240 is an inverting octal buffer and line
driver designed to be employed as a memory address driver,
clock driver and bus oriented transmitter or receiver which
provides improved PC board density. The ’ACQ/’ACTQ uti-
lizes NSC Quiet Series technology to guarantee quiet output
switching and improve dynamic threshold performance.
FACT Quiet Series features GTO output control and un-
dershoot corrector in addition to a split ground bus for supe-
rior performance.
Features
n ICC and IOZ reduced by 50%
n Guaranteed simultaneous switching noise level and
dynamic threshold performance
n Improved latch-up immunity
n Inverting TRI-STATE outputs drive bus lines or buffer
memory address registers
n Outputs source/sink 24 mA
n Faster prop delays than the standard ’ACT240
n 4 kV minimum ESD immunity
n Standard Microcircuit Drawing (SMD)
