| SN54/74LS299 8-BIT SHIFT/STORAGE REGISTER WITH 3-STATE OUTPUTS The SN54 / 74LS299 is an 8-Bit Universal Shift / Storage Register with 3-state outputs. Four modes of operation are possible: hold (store), shift left, shift right and load data. The parallel load inputs and flip-flop outputs are multiplexed to reduce the total number of package pins. Separate outputs are provided for flip-flops Q0 and Q7 to allow easy cascading. A separate active LOW Master Reset is used to reset the register. 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, Load and Store * Separate Shift Right Serial Input and Shift Left Serial Input for Easy Cascading * 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) V CC 20 S 1 19 D s7 18 Q 7 17 I/O 7 16 I/O 5 15 I/O 3 14 I/O 1 13 CP 12 DS 0 11 20 NOTE: The Flatpak version has the same pinouts (Connection Diagram) as the Dual In-Line Package. 1 DW SUFFIX SOIC CASE 751D-03 ORDERING INFORMATION SN54LSXXXJ Ceramic SN74LSXXXN Plastic SN74LSXXXDW SOIC 1 S 0 2 OE 1 3 OE 2 4 I/O 6 5 I/O 4 6 I/O 2 7 I/O 0 8 Q 0 9 MR 10 GND PIN NAMES HIGH CP DS0 DS7 I/On OE1, OE2 Q0, Q7 MR S0, S1 Clock Pulse (active positive-going edge) Input Serial Data Input for Right Shift Serial Data Input for Left Shift Parallel Data Input or Parallel Output (3-State) (Note c) 3-State Output Enable (active LOW) Inputs Serial Outputs (Note b) Asynchronous Master Reset (active LOW) Input Mode Select Inputs LOADING (Note a) LOW 0.25 U.L. 0.25 U.L. 0.25 U.L. 0.25 U.L. 15 (7.5) U.L. 0.25 U.L. 5 (2.5) U.L. 0.25 U.L. 0.5 U.L. 0.5 U.L. 0.5 U.L. 0.5 U.L. 0.5 U.L. 65 (25) U.L. 0.5 U.L. 10 U.L. 0.5 U.L. 1 U.L.
