SN74AHCT08QPWRG4Q1

Texas Instruments · Logic Gates · TSSOP-14

SN74AHCT08QPWRG4Q1 from Texas Instruments, in a TSSOP-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; a TTL-compatible input rated 0 V to 5.5 V that is high impedance when VCC = 0 V.
2	1B	input	Gate 1 input B; a TTL-compatible input rated 0 V to 5.5 V that is high impedance when VCC = 0 V.
3	1Y	output	Gate 1 output Y (Y = A·B); continuous output current is limited to ±25 mA per the absolute maximum ratings.
4	2A	input	Gate 2 input A; a TTL-compatible input rated 0 V to 5.5 V that is high impedance when VCC = 0 V.
5	2B	input	Gate 2 input B; a TTL-compatible input rated 0 V to 5.5 V that is high impedance when VCC = 0 V.
6	2Y	output	Gate 2 output Y (Y = A·B); continuous output current is limited to ±25 mA per the absolute maximum ratings.
7	GND	power_in	Ground reference for the device.
8	3Y	output	Gate 3 output Y (Y = A·B); continuous output current is limited to ±25 mA per the absolute maximum ratings.
9	3A	input	Gate 3 input A; a TTL-compatible input rated 0 V to 5.5 V that is high impedance when VCC = 0 V.
10	3B	input	Gate 3 input B; a TTL-compatible input rated 0 V to 5.5 V that is high impedance when VCC = 0 V.
11	4Y	output	Gate 4 output Y (Y = A·B); continuous output current is limited to ±25 mA per the absolute maximum ratings.
12	4A	input	Gate 4 input A; a TTL-compatible input rated 0 V to 5.5 V that is high impedance when VCC = 0 V.
13	4B	input	Gate 4 input B; a TTL-compatible input rated 0 V to 5.5 V that is high impedance when VCC = 0 V.
14	VCC	power_in	Positive supply; recommended operating range is 4.5 V to 5.5 V.
