STMicroelectronics M74HC75B1 Quad Latch

The M74HC75B1 is a high-speed CMOS Quad Latch manufactured by STMicroelectronics, designed to operate in a wide range of applications from industrial to consumer electronics. This integrated circuit is part of the HC family, which ensures a robust performance with high noise immunity and low power consumption.

The device features four latches with separate data (D) inputs and latch enable (LE) inputs. Each latch is capable of storing one bit of information, and the data is transferred to the latch output only when the latch enable input is held high. The information is retained as long as the latch enable remains in the high state, making it ideal for capturing and holding data.

Key specifications of the M74HC75B1 include:

• Wide operating voltage range from 2V to 6V, which allows for flexible use in various circuit designs and compatibility with TTL levels.
• Low quiescent current consumption, which is essential for battery-operated devices, contributing to energy efficiency and longer battery life.
• High noise immunity characteristic of CMOS technology, ensuring reliable operation even in electrically noisy environments.
• Ability to drive up to 10 LSTTL loads, providing sufficient output current for interfacing with other logic families.

The M74HC75B1 comes in a standard DIP-16 (Dual In-line Package) or SO-16 (Small Outline) package, making it easy to integrate into both through-hole and surface-mount PCB designs. The pin configuration is designed for straightforward implementation, with clearly marked inputs and outputs for each of the four latches.

STMicroelectronics provides detailed datasheets with complete electrical characteristics and application information, ensuring engineers have all necessary data for incorporating the M74HC75B1 into their designs. Whether used in data storage, signal processing, or digital logic circuits, the M74HC75B1 is a reliable and efficient choice for designers in need of a high-performance quad latch.
