SN54LS323

SN54/74LS323 8-BIT SHIFT/STORAGE REGISTER WITH 3-STATE OUTPUTS The SN54 / 74LS323 is an 8-Bit Universal Shift / Storage Register with 3-state outputs. Its function is similar to the SN54 / 74LS299 with the exception of Synchronous Reset. Parallel load inputs and flip-flop outputs are multiplexed to minimize pin count. Separate inputs and outputs are provided for flip-flops Q0 and Q7 to allow easy cascading. Four operation modes are possible: hold (store), shift left, shift right, and parallel load. All modes are activated on the LOW-to-HIGH transition of the Clock. 8-BIT SHIFT/STORAGE REGISTER WITH 3-STATE OUTPUTS LOW POWER SCHOTTKY Common I/O for Reduced Pin Count Four Operation Modes: Shift Left, Shift Right, Parallel Load and Store Separate Continuous Inputs and Outputs from Q0 and Q7 Allow Easy Cascading Fully Synchronous Reset 3-State Outputs for Bus Oriented Applications Input Clamp Diodes Limit High-Speed Termination Effects ESD > 3500 Volts 20 1 J SUFFIX CERAMIC CASE 732-03 20 N SUFFIX PLASTIC CASE 738-03 1 CONNECTION DIAGRAM DIP (TOP VIEW) VCC S1 20 19 DS7 Q7 18 17 I/O7 I/O5 I/O3 I/O1 CP 16 15 14 13 12 DS0 11 NOTE: The Flatpak version has the same pinouts (Connection Diagram) as the Dual In-Line Package. 20 1 DW SUFFIX SOIC CASE 751D-03 ORDERING INFORMATION SN54LSXXXJ Ceramic SN74LSXXXN Plastic SN74LSXXXDW SOIC 1 S0 8 2 3 4 5 6 7 OE1 OE2 I/O6 I/O4 I/O2 I/O0 Q0 9 10 SR GND PIN NAMES HIGH CP DS0 DS7 I/On OE1, OE2 Q0, Q7 S0, S1 SR Clock Pulse ...
