SN74HC21NSRG4: Dual 4-Input AND Gate from Texas Instruments

The SN74HC21NSRG4 is a high-performance, dual 4-input AND gate integrated circuit (IC) manufactured by Texas Instruments (TI), a leader in the semiconductor industry. This IC is part of the 'HC' series, which are high-speed CMOS logic devices designed to operate with the same speed as LS-TTL (Low-Power Schottky Transistor-Transistor Logic) devices while maintaining the CMOS low power dissipation.

With its industry-standard SOIC-14 package, the SN74HC21NSRG4 is suitable for a wide range of applications, from consumer electronics to industrial control systems. The device features two independent 4-input AND gates, which makes it ideal for implementing logic functions where a high number of inputs are required to be logically 'ANDed' together.

Key Features:

• Operating Voltage Range: 2 V to 6 V
• High On-Output Drive Capability: Capable of driving 15 LSTTL loads
• Low Power Consumption: 20 µA Maximum ICC at 4 V
• Balanced Propagation Delays: Provides consistent performance
• Low Input Current: 1 µA Maximum
• Wide Operating Temperature Range: -40°C to 85°C

The SN74HC21NSRG4 benefits from TI's advanced silicon-gate CMOS technology, which ensures that the device has a reduced risk of latch-up when exposed to high energy. Additionally, the IC is characterized for operation from -40°C to 85°C, making it robust enough for most environmental conditions.

Its logic level compatibility allows for seamless integration with other TTL and CMOS components within a system. The SN74HC21NSRG4 is also characterized for use in noise-sensitive applications, thanks to its low noise characteristics.

Whether you're designing a complex digital system or looking for a reliable component for logic operations, the SN74HC21NSRG4 from Texas Instruments is a versatile and dependable choice that offers both high performance and energy efficiency.
