SN7425N

Texas Instruments · Gates · PDIP-14

SN7425N from Texas Instruments, in a PDIP-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 data input A; high-level input voltage at least 2 V and low-level at most 0.8 V.
2 1B input Gate 1 data input B; high-level input voltage at least 2 V and low-level at most 0.8 V.
3 1G input Gate 1 strobe input G; output 1Y is forced high when G is low.
4 1C input Gate 1 data input C; high-level input voltage at least 2 V and low-level at most 0.8 V.
5 1D input Gate 1 data input D; high-level input voltage at least 2 V and low-level at most 0.8 V.
6 1Y output Gate 1 output Y = NOT[G(A+B+C+D)], rated for 16 mA low-level and -0.8 mA high-level output current.
7 GND power_in Ground (network ground terminal), reference for all voltages.
8 2Y output Gate 2 output Y = NOT[G(A+B+C+D)], rated for 16 mA low-level and -0.8 mA high-level output current.
9 2A input Gate 2 data input A; high-level input voltage at least 2 V and low-level at most 0.8 V.
10 2B input Gate 2 data input B; high-level input voltage at least 2 V and low-level at most 0.8 V.
11 2G input Gate 2 strobe input G; output 2Y is forced high when G is low.
12 2C input Gate 2 data input C; high-level input voltage at least 2 V and low-level at most 0.8 V.
13 2D input Gate 2 data input D; high-level input voltage at least 2 V and low-level at most 0.8 V.
14 VCC power_in Supply voltage, 4.75 V to 5.25 V recommended for the 74 family, 7 V absolute maximum.
