National Semiconductor 54ACQ374
The ’ACQ/’ACTQ374 is a high-speed, low-power octal D-type flip-flop featuring separate D-type inputs for each flip-flop and TRI-STATE outputs for bus-oriented applications. The ’ACQ/’ACTQ374 utilizes Quiet Series technology to guarantee quiet output switching and improve dynamic threshold performance.GENERAL DESCRIPTION
A buffered Clock (CP) and Output Enable (OE) are common to all flip-flops. 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 Buffered positive edge-triggered clock 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/’ACT374 n 4 kV minimum ESD immunity n Standard Military Drawing (SMD) — ’ACTQ374: 5962-92189 — ’ACQ374: 5962-92179FEATURES
