The Texas Instruments SN54HC21J is a high-speed dual 4-input AND gate belonging to the HC logic family. Each independent gate performs the Boolean function Y = A • B • C • D in positive logic. This device is designed for military applications, operating over a wide voltage range of 2V to 6V and an extended temperature range of -55°C to 125°C.
With a typical output drive strength of 5.2 mA (IOL) and -5.2 mA (IOH), the SN54HC21J supports fanout up to 10 LSTTL loads. Its standard CMOS input type and push-pull output type ensure reliable performance. The high-speed operation, with propagation delays between 10-50 ns, makes it suitable for various digital logic applications.
Available in CDIP (J) and LCCC (FK) packages, this AND gate offers buffered inputs for enhanced signal integrity. It provides significant power reduction compared to LSTTL logic ICs, making it an efficient choice for demanding environments. The SN54HC21J is a robust component for digital circuit design requiring precise AND logic functions.
