54ACQ573 • 54ACTQ573 Quiet Series Octal Latch with TRI-STATE® Outputs General Description The ’ACQ/’ACTQ573 is a high-speed octal latch with buff- ered common Latch Enable (LE) and buffered common Out- put Enable (OE) inputs. The ’ACQ/’ACTQ573 is functionally identical to the ’ACQ/’ACTQ373 but with inputs and outputs on opposite sides of the package. 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 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 Inputs and outputs on opposite sides of package allow easy interface with microprocessors n Outputs source/sink 24 mA n Faster prop delays than standard ’ACT573 n 4 kV minimum ESD immunity n Standard Microcircuit Drawing (SMD) — ’ACTQ573: 5962-92194 — ’ACQ573: 5962-92180 Logic Symbols Pin Names Description D 0–D7 Data Inputs LE Latch Enable Input OE TRI-STATE Output Enable Input O 0–O7 TRI-STATE Latch Outputs GTO™ is a trademark of National Semiconductor Corporation.
