The SN74HCS21DR from Texas Instruments is a dual 4-input AND gate integrated circuit. Each gate within the device performs the Boolean function Y = A ● B ● C ● D in positive logic. This component is designed with Schmitt-trigger inputs, which allows for tolerance to slow or noisy input signals, enhancing reliability in various applications.
Key electrical characteristics include a wide operating voltage range from 2V to 6V. The device exhibits low power consumption, with a typical supply current (ICC) of 100 nA and a typical input leakage current of ±100 nA. It provides an output drive of ±7.8 mA at 5V. The maximum propagation delay is specified at 16 ns at 6V with a 50 pF load capacitance.
The SN74HCS21DR operates within an extended ambient temperature range of -40°C to +125°C. It is housed in a 14-SOIC package with dimensions of 8.70 mm × 3.90 mm, suitable for surface mounting. This logic gate is well-suited for applications such as combining power good signals or enabling digital signals where robust input handling is required.
