Four independent 2-input NAND gates in high-speed CMOS logic, in a SOIC-14 package. Each gate computes Y = NOT(A AND B). NAND is functionally complete, so this one part builds any logic function, and it is the go-to for simple gating, set-reset latches, and RC oscillators. Runs 2-6 V and drives TTL/CMOS loads directly.

Pinout

Pin	Name	Type	Function
1	1A	input	Channel 1, Input A. CMOS logic input to NAND gate 1 (V_IH >= 3.15 V @ Vcc=4.5 V; V_IL <= 1.35 V @ Vcc=4.5 V). Input leakage +/-0.1 uA typ, +/-1000 nA max.
2	1B	input	Channel 1, Input B. CMOS logic input to NAND gate 1, paired with 1A.
3	1Y	output	Channel 1, Output Y. Push-pull CMOS output equal to NOT(1A AND 1B). Balanced drive of +/-5.2 mA at Vcc = 6 V.
4	2A	input	Channel 2, Input A. CMOS logic input to NAND gate 2.
5	2B	input	Channel 2, Input B. CMOS logic input to NAND gate 2, paired with 2A.
6	2Y	output	Channel 2, Output Y. Push-pull CMOS output equal to NOT(2A AND 2B).
7	GND	power_in	Ground reference (0 V). Continuous current through GND limited to +/-50 mA.
8	3Y	output	Channel 3, Output Y. Push-pull CMOS output equal to NOT(3A AND 3B).
9	3A	input	Channel 3, Input A. CMOS logic input to NAND gate 3.
10	3B	input	Channel 3, Input B. CMOS logic input to NAND gate 3, paired with 3A.
11	4Y	output	Channel 4, Output Y. Push-pull CMOS output equal to NOT(4A AND 4B).
12	4A	input	Channel 4, Input A. CMOS logic input to NAND gate 4.
13	4B	input	Channel 4, Input B. CMOS logic input to NAND gate 4, paired with 4A.
14	VCC	power_in	Positive supply. Recommended 2 V to 6 V (5 V nominal); absolute max 7 V. Decouple to GND with a 100 nF ceramic capacitor close to the pin.
