SN74HC151DR from Texas Instruments, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 D3 input Data input channel 3. Selected and routed to Y (and inverted to W) when select inputs C,B,A = 011 and strobe G is low.
2 D2 input Data input channel 2. Selected and routed to Y (and inverted to W) when select inputs C,B,A = 010 and strobe G is low.
3 D1 input Data input channel 1. Selected and routed to Y (and inverted to W) when select inputs C,B,A = 001 and strobe G is low.
4 D0 input Data input channel 0. Selected and routed to Y (and inverted to W) when select inputs C,B,A = 000 and strobe G is low.
5 Y output True (non-inverted) data output. Reflects the selected D input while strobe G is low; forced low when G is high. Drives up to 10 LSTTL loads (±6 mA at 5 V).
6 W output Complementary (inverted) data output. Reflects the inverse of the selected D input while strobe G is low; forced high when G is high. Drives up to 10 LSTTL loads (±6 mA at 5 V).
7 G input Active-low strobe (enable) input. Must be low to enable the multiplexer; a high level forces Y low and W high regardless of the D inputs and select code.
8 GND power_in Ground reference (0 V) for the device.
9 C input Binary select input C (MSB of the 3-bit channel select). Together with B and A selects one of D0-D7 to route to Y/W.
10 B input Binary select input B (middle bit of the 3-bit channel select).
11 A input Binary select input A (LSB of the 3-bit channel select).
12 D7 input Data input channel 7. Selected when C,B,A = 111 and strobe G is low.
13 D6 input Data input channel 6. Selected when C,B,A = 110 and strobe G is low.
14 D5 input Data input channel 5. Selected when C,B,A = 101 and strobe G is low.
15 D4 input Data input channel 4. Selected when C,B,A = 100 and strobe G is low.
16 VCC power_in Positive supply voltage. Recommended operating range 2 V to 6 V (5 V nominal); absolute maximum 7 V.

CAD (KiCad official)

  • Symbol: SN74HC151DR
  • Footprint: Package_SO:SOIC-16_3.9x9.9mm_P1.27mm
  • 3D model: SOIC-16 (KiCad packages3D, STEP)
  • 3D model files: sn74hc151dr-etched.step / sn74hc151dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn74hc151dr.step / sn74hc151dr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (28 pp, sha256 52a419ef9dca8855, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
