SN74S08D

Texas Instruments · Logic Gates · SOIC-14

SN74S08D from Texas Instruments, in a SOIC-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 1A input Gate 1 input A; input voltage must not exceed 5.5 V for the 'S08.
2 1B input Gate 1 input B; input voltage must not exceed 5.5 V for the 'S08.
3 1Y output Gate 1 output, Y = A·B (high only when both 1A and 1B are high).
4 2A input Gate 2 input A; input voltage must not exceed 5.5 V for the 'S08.
5 2B input Gate 2 input B; input voltage must not exceed 5.5 V for the 'S08.
6 2Y output Gate 2 output, Y = A·B (high only when both 2A and 2B are high).
7 GND power_in Ground, the network ground terminal that all voltage values are referenced to.
8 3Y output Gate 3 output, Y = A·B (high only when both 3A and 3B are high).
9 3A input Gate 3 input A; input voltage must not exceed 5.5 V for the 'S08.
10 3B input Gate 3 input B; input voltage must not exceed 5.5 V for the 'S08.
11 4Y output Gate 4 output, Y = A·B (high only when both 4A and 4B are high).
12 4A input Gate 4 input A; input voltage must not exceed 5.5 V for the 'S08.
13 4B input Gate 4 input B; input voltage must not exceed 5.5 V for the 'S08.
14 VCC power_in Supply voltage, absolute maximum 7 V with respect to GND.
