SN74LS93N

Texas Instruments · Counters, Dividers · DIP-14

SN74LS93N from Texas Instruments, in a DIP-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CKB input Clock input to the divide-by-eight section (Q B, QC, QD), connected to QA for the full 4-bit binary count.
2 R0(1) input Gated zero-reset input; when both R0(1) and R0(2) are high the counter is reset to zero.
3 R0(2) input Gated zero-reset input; when both R0(1) and R0(2) are high the counter is reset to zero.
4 NC unconnected No internal connection.
5 VCC power_in Positive supply voltage.
6 NC unconnected No internal connection.
7 NC unconnected No internal connection.
8 QC output Counter output C, the third bit of the binary count.
9 QB output Counter output B, the second bit of the binary count.
10 GND power_in Ground.
11 QD output Counter output D, the most significant bit of the binary count.
12 QA output Counter output A, the divide-by-two output and least significant bit.
13 NC unconnected No internal connection.
14 CKA input Clock input to the divide-by-two section; input count pulses are applied here.

CAD (KiCad official)

  • Symbol: SN74LS93N
  • Footprint: Package_DIP:DIP-14_W7.62mm
  • 3D model: DIP-14 (KiCad packages3D, STEP)
  • 3D model files: sn74ls93n-etched.step / sn74ls93n-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn74ls93n.step / sn74ls93n.glb are the bare package body.
