The SN74HCS21PWR from Texas Instruments is a dual 4-input AND gate designed for digital logic applications. Each of the two independent gates performs the Boolean function Y = A ● B ● C ● D in positive logic. A key feature is its Schmitt-trigger inputs, which allow the device to reliably process slow or noisy input signals, enhancing system stability.
This device operates over a wide voltage range of 2 V to 6 V, making it versatile for various power supply environments. It exhibits low power consumption, with a typical supply current of only 100 nA and a typical input leakage current of ±100 nA. The output drive capability is ±7.8 mA at 5 V, suitable for driving moderate loads. The maximum propagation delay is 16 ns at 6 V with a 50 pF load.
Designed for surface mounting, the SN74HCS21PWR comes in a compact 14-TSSOP package measuring 5.00 mm × 4.40 mm. Its extended ambient temperature range of -40°C to +125°C ensures reliable operation in demanding conditions. Applications include combining power good signals and enabling digital signals where robust input handling is required.
