74LCX00FT from TOSHIBA, in a TSSOP-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 Gate 1, input A. CMOS input with 5-V tolerance (VIN 0 to 5.5 V). High-level input voltage VIH = VCC x 0.9 min (1.65-2.3 V range).
2 1B input Gate 1, input B. CMOS input with 5-V tolerance. Pairs with 1A into the first NAND gate.
3 1Y output Gate 1 NAND output. Y = NAND(1A, 1B). Drives
4 2A input Gate 2, input A. CMOS input with 5-V tolerance.
5 2B input Gate 2, input B. CMOS input with 5-V tolerance.
6 2Y output Gate 2 NAND output. Y = NAND(2A, 2B). Drives 24 mA min at VCC = 3.0 V.
7 GND power_in Ground reference (0 V) for the device.
8 3Y output Gate 3 NAND output. Y = NAND(3A, 3B). Drives 24 mA min at VCC = 3.0 V.
9 3A input Gate 3, input A. CMOS input with 5-V tolerance.
10 3B input Gate 3, input B. CMOS input with 5-V tolerance.
11 4Y output Gate 4 NAND output. Y = NAND(4A, 4B). Drives 24 mA min at VCC = 3.0 V.
12 4A input Gate 4, input A. CMOS input with 5-V tolerance.
13 4B input Gate 4, input B. CMOS input with 5-V tolerance.
14 VCC power_in Positive supply voltage. Operating range VCC = 1.65 to 3.6 V (absolute max 6.5 V). Bypass with a 0.1 uF ceramic close to the pin.
