54ACQ240 Datasheet | National Semiconductor

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 utilizes NSC Quiet Series technology to guarantee quiet output switching and improve dynamic 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 Inverting TRI-STATE outputs drive bus lines or buffer memory address registers n Outputs source/sink 24 m A n Faster prop delays than the standard ’ACT240 n 4 k V minimum ESD immunity n Standard Microcircuit Drawing (SMD) ’ACTQ240: 5962-92184 Features n ICC and IOZ reduced by 50% Logic Symbol IEEE/IEC Connection Diagrams Pin Assignment for DIP and Flatpak DS100235-1 DS100235-2 Pin Names OE1, OE2 I0- I7 O0- O7 Inputs Outputs Description TRI-STATE Output Enable Inputs Pin Assignment for LCC DS100235-3 GTO™ is a trademark of National Semiconductor Corporation.
