5-bit shift register 7496

The 5-bit shift register 7496 is a 7400-series TTL logic IC containing five flip-flops connected as a shift register. Data enters through a serial input and moves one stage on each rising clock edge, and all five outputs (QA to QE) are available at once, so it works as a serial-in/parallel-out or serial-in/serial-out register. Preset inputs and a clear input also let you load a 5-bit word in parallel.

5-bit shift register 7496 Specifications

• Function: 5-bit shift register, shift right
• Inputs: serial data, clock, /CLEAR (active LOW), preset enable and 5 preset inputs (A to E)
• Outputs: QA to QE, all accessible
• Clocking: shifts on the rising (positive-going) clock edge
• Clear: asynchronous, sets all outputs LOW
• Logic family: 7400 series TTL
• Supply voltage: 5 V
• Package: 16-pin DIP
• Power pins: pin 5 = VCC, pin 12 = GND

5-bit shift register 7496 Applications

• Serial-to-parallel conversion for driving LEDs or relay drivers
• Delay lines and sequence generators
• Ring and Johnson counters, with feedback from QE to the serial input
• Storing and shifting 5-bit data words
• Digital logic labs and university electronics courses

What's in the Box

• 1 × 7496 5-bit shift register IC

Tip: To load data in parallel, first pulse /CLEAR LOW, then take preset enable HIGH with the wanted bits HIGH on inputs A to E; the presets can only set bits to 1. Note that VCC is pin 5 and GND is pin 12, not the corner pins used on most logic ICs, so check the pinout before powering up.
