54ACTQ244 Datasheet | National Semiconductor

Description The ’ACQ/’ACTQ244 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 ACQ/ACTQ utilizes NSC Quiet Series technology to guarantee quiet output switching and improved 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 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 ’AC/’ACT244 n 4 k V minimum ESD immunity n Standard Microcircuit Drawing (SMD) - ’ACTQ244: 5962-92186 - ’ACQ244: 5962-92176 Features n ICC and IOZ reduced by 50% Logic Symbol IEE/IEC Connection Diagrams Pin Assignment for DIP and Flatpak DS100236-1 DS100236-2 Pin Names OE1, OE2 I0- I 7 O0- O 7 Inputs Outputs Description TRI-STATE Output Enable Inputs Pin Assignment for LCC DS100236-3 GTO™ is a trademark of National Semiconductor Corporation.
