It contains two independent 4-input AND functions, each output high only when all four inputs are high. ## Quiescent current and output drive Quiescent current sits at 2 µA max, making this gate negligible in the power budget for battery-backed or always-on logic.","metaTitle":"SN74HC21PW TI 74HC AND Gate, 2V-6V Supply, 14-TSSOP","metaDescription":"SN74HC21PW Texas Instruments 74HC dual 4-input AND gate. 2V to 6V supply, 19ns delay at 6V/50pF, -40°C to 85°C.
