Texas Instruments · Inverters · SOIC-14

SN74HC05DR from Texas Instruments, in a SOIC-14. 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 1A input Channel 1, Input A. CMOS logic input to inverter 1; VIH >= 4.2 V at VCC = 6 V, VIL <= 1.8 V at VCC = 6 V.
2 1Y output Channel 1, Output Y. Open-drain inverting output (Y = /A). Requires external pull-up resistor to VCC; sinks up to 5.2 mA at VCC = 6 V.
3 2A input Channel 2, Input A. CMOS logic input to inverter 2.
4 2Y output Channel 2, Output Y. Open-drain inverting output (Y = /A). Requires external pull-up.
5 3A input Channel 3, Input A. CMOS logic input to inverter 3.
6 3Y output Channel 3, Output Y. Open-drain inverting output (Y = /A). Requires external pull-up.
7 GND power_in Ground reference (0 V) for the device.
8 4Y output Channel 4, Output Y. Open-drain inverting output (Y = /A). Requires external pull-up.
9 4A input Channel 4, Input A. CMOS logic input to inverter 4.
10 5Y output Channel 5, Output Y. Open-drain inverting output (Y = /A). Requires external pull-up.
11 5A input Channel 5, Input A. CMOS logic input to inverter 5.
12 6Y output Channel 6, Output Y. Open-drain inverting output (Y = /A). Requires external pull-up.
13 6A input Channel 6, Input A. CMOS logic input to inverter 6.
14 VCC power_in Positive supply voltage. Recommended operating range 2 V to 6 V (nominal 5 V); absolute max 7 V.
