Part Details:

54ACT564 September 1998 54ACT564 Octal Octal D-Type Flip-Flop with TRI-STATE® Outputs General Description Features D-T The ACT564 is a high-speed, low power octal flip-flop with a n I and I reduced by 50% CC OZ buffered common Clock (CP) and a buffered common Out- n Inputs and outputs on opposite sides of package ype put Enable (OE). The information presented to the D inputs allowing easy interface with microprocessors is stored in the flip-flops on the LOW-to-HIGH Clock (CP) n Useful as input or output port for microprocessors transition. Flip-Flop n Functionally identical to ACT574 but with inverted The ACT564 is functionally identical to the ACT574, but outputs with inverted outputs. n TRI-STATE outputs for bus-oriented applications n Outputs source/sink 24 mA n ACT564 has TTL-compatible inputs n Standard Microcircuit Drawing (SMD) 5962-89557 with Logic Symbols TRI-ST IEEE/IEC ATEOutputs DS100994-1 DS100994-2 Pin Names Description D ­D Data Inputs 0 7 CP Clock Pulse Input OE TRI-STATE Output Enable Input O ­O TRI-STATE Outputs 0 7 TRI-STATE® is a registered trademark of National Semiconductor Corporation.FACTTM is a trademark of Fairchild Semiconductor Corporation. © 1998 National Semiconductor Corporation DS100994
