54ACTQ241
Quiet Series Octal Buffer/Line Driver with TRI-STATE^®
Outputs
General Description
The ACTQ241 is an 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 ACTQ utilizes NSC Quiet Series tech-
nology to guarantee quiet output switching and improved dy-
namic threshold performance. FACT Quiet Series™ features
GTO™ output control and undershoot corrector in addition to
a split ground bus for superior performance.
n Guaranteed simultaneous switching noise level and
dynamic threshold performance
n Improved latch-up immunity
n TRI-STATE outputs drive bus lines or buffer memory
address registers
n Outputs source/sink 24 mA
n Faster prop delays than the standard ’AC/’ACT241
n 4 kV minimum ESD immunity (’ACTQ)
n Standard Microcircuit Drawing (SMD) 5962-92185
Features
n I_CC and I_OZ reduced by 50%
