54AC574 • 54ACT574 Octal D-Type Flip-Flop with TRI-STATE® Outputs General Description The ’AC/’ACT574 is a high-speed, low power octal flip-flop with a buffered common Clock (CP) and a buffered common Output Enable (OE). The information presented to the D in- puts is stored in the flip-flops on the LOW-to-HIGH Clock (CP) transition. The ’AC/’ACT574 is functionally identical to the ’AC/’ACT374 except for the pinouts. Features n ICC and IOZ reduced by 50% n Inputs and outputs on opposite sides of package allowing easy interface with microprocessors n Useful as input or output port for microprocessors n Functionally identical to ’AC/’ACT374 n TRI-STATE outputs for bus-oriented applications n Outputs source/sink 24 mA n ’ACT574 has TTL-compatible inputs n Standard Microcircuit Drawing (SMD) — ’ACT574: 5962-89601 Logic Symbols Pin Names Description D 0–D7 Data Inputs CP Clock Pulse Input OE TRI-STATE Output Enable Input O 0–O7 TRI-STATE Outputs TRI-STATE® is a registered trademark of National Semiconductor Corporation.
