CD74HC373E TI Harris CMOS High Speed Octal Latch 5 Pack 2 to 6V

Description

Product Overview

The CD74HC373E from Texas Instruments and Harris is a high‑speed CMOS octal transparent latch designed for demanding digital applications. Each device features eight D‑type latches with three‑state outputs, allowing seamless integration into complex logic designs. Operating voltage ranges from 2 V to 6 V, the IC delivers low power consumption while maintaining fast propagation delays and balanced transition times. Packaged in a DIP‑20 format, the component is breadboard‑friendly and ideal for rapid prototyping, yet robust enough for production environments. The device’s specifications include a wide operating temperature range of –55 °C to 125 °C, ensuring reliable performance across industrial and scientific settings. Standard outputs can drive up to 15 LS‑TTL loads, providing flexibility for interfacing with legacy logic families. This 5‑pack offering gives designers the convenience of multiple units for testing, development, and final assembly.

Usage

The CD74HC373E excels in applications where data must be held transparent while a clock signal is active, such as bus‑oriented architectures, register files, and memory interfacing. Its three‑state outputs enable easy bus sharing, making it a perfect choice for multiplexed data lines in microcontroller and FPGA designs. Engineers working on NAND logic gates, shift registers, and state machines will find the device’s low‑power operation advantageous for battery‑powered or energy‑constrained systems. The wide voltage range supports both 3.3 V and 5 V logic levels, allowing seamless integration into mixed‑voltage environments. Additionally, the device’s temperature tolerance makes it suitable for automotive, aerospace, and industrial control applications where environmental extremes are common.
