74HC21D,653

The 74HC21D,653 from Nexperia is a high-speed Si-gate CMOS device that functions as a dual 4-input AND gate. It operates over a wide supply voltage range of 2.0 V to 6.0 V, making it suitable for various applications. The device offers low power dissipation and high noise immunity, characteristic of CMOS technology.

Key electrical specifications include a maximum propagation delay of 19 ns at 6V and 50pF, and input logic levels ranging from 1.5 V to 4.2 V. The quiescent current is typically 5.2 mA. The operating temperature range is -40 °C to +125 °C, ensuring reliable performance in demanding environments.

This component is supplied in a 14-lead SOIC package (SO14, SOT108-1) with a body width of 3.9 mm, designed for surface mounting. It features clamp diodes on the inputs, allowing the use of current-limiting resistors for interfacing with voltages exceeding VCC. The 74HC21D,653 complies with JEDEC standards JESD8C and JESD7A, and offers robust ESD protection exceeding 2000 V for HBM class 2 and 1000 V for CDM class C3.

With its dual 4-input AND gate configuration, wide operating voltage, and compact package, the 74HC21D,653 is well-suited for digital logic applications requiring reliable AND function implementation.
