| SN74LS299 8-Bit Shift/Storage Register with 3-State Outputs The SN74LS299 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. http://onsemi.com * 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 LOW POWER SCHOTTKY GUARANTEED OPERATING RANGES Symbol VCC TA IOH IOL IOH IOL Parameter Supply Voltage Operating Ambient Temperature Range Output Current - High Q 0 , Q7 Output Current - Low Q 0 , Q7 Output Current - High I/O0 - 1/O7 Output Current - Low I/O0 - 1/O7 Min 4.75 0 Typ 5.0 25 Max 5.25 70 - 0.4 8.0 - 2.6 24 Unit V C mA mA mA mA 1 PLASTIC N SUFFIX CASE 738 20 1 SOIC DW SUFFIX CASE 751D ORDERING INFORMATION Device SN74LS299N SN74LS299DW Package 16 Pin DIP 16 Pin Shipping 1440 Units/Box 2500/Tape & Reel (c) Semiconductor Components Industries, LLC, 1999 1 December, 1999 - Rev. 6 Publication Order Number: SN74LS299/D SN74LS299 CONNECTION DIAGRAM DIP (TOP VIEW) VCC 20 S1 19 Ds7 18 Q7 17 I/O7 I/O5 I/O3 I/O1 16 15 14 13 CP 12 DS0 11 NOTE: The Flatpak version has the same pinouts (Connection Diagram) as the Dual In-Line Package. 1 S0 2 3 4 OE1 OE2 I/O6 8 5 6 7 I/O4 I/O2 I/O0 Q0 9 10 MR GND LOADING (Note a) PIN NAMES 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) 3-State Output Enable (Active LOW) Inputs Serial Outputs Asynchronous Master Reset (Active LOW) Input Mode Select Inputs HIGH 0.5 U.L. 0.5 U.L. 0.5 U.L. 0.5 U.L. 65 U.L. 0.5 U.L. 10 U.L. 0.5 U.L. 1 U.L.
