1 / 8 page 54ACTQ574 Quiet Series Octal D Flip-Flop with TRI-STATE® Outputs General Description The ACTQ574 is a high-speed, low-power octal D-type flip-flop with a buffered Common Clock (CP) and a buffered common Output Enable (OE). The information presented to the D inputs is stored in the flip-flops on the LOW-to-HIGH clock (CP) transition. ACTQ574 utilizes Quiet Series technology to guarantee quiet output switching and improve dynamic threshold per- formance. FACT Quiet Series™ features GTO™ output con- trol and undershoot corrector in addition to a split ground bus for superior performance. The ACTQ574 is functionally identical to the ’ACTQ374 but with different pin-out. Features n ICC and IOZ reduced by 50% n Guaranteed simultaneous switching noise level and dynamic threshold performance n Inputs and outputs on opposite sides of the package allowing easy interface with microprocessors n Functionally identical to the ACTQ374 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 ACT574 n 4 kV minimum ESD immunity Logic Diagrams Pin Names Description D 0–D7 Data Inputs CP Clock Pulse Input OE TRI-STATE Output Enable Input O 0–O7 TRI-STATE Outputs GTO™ is a trademark of National Semiconductor Corporation.
