CD74HC75E TI Speed CMOS Dual 2-Bit Bistable Latch DIP-16 Pack of 10

Description

Product Overview

The CD74HC75E is a high‑speed CMOS logic device from Texas Instruments that combines two independent 2‑bit bistable transparent latches into a single 16‑pin DIP package. Each latch provides true and complementary outputs, allowing designers to implement flexible data storage and transfer functions without additional inversion circuitry. The device operates over a wide voltage range of 2 V to 6 V, making it suitable for both low‑voltage battery‑powered designs and higher‑voltage industrial systems. Its fan‑out capability supports up to ten LSTTL loads on the standard outputs and fifteen LSTTL loads on the bus driver outputs, ensuring reliable signal distribution across complex boards. The IC’s low power consumption, balanced propagation delay, and robust temperature range from –55 °C to 125 °C contribute to stable performance in harsh environments. The DIP‑16 form factor is breadboard‑friendly, enabling quick prototyping and easy insertion into standard sockets for both development and production use.

Usage

Engineers and hobbyists alike find the CD74HC75E valuable in a variety of applications where data must be held temporarily while a system transitions between states. Typical use cases include register files in microcontroller interfaces, edge‑triggered timing circuits, and multiplexed data buses in communication modules. The transparent latch architecture allows the device to pass input data directly to the output when the enable pin is active, then retain the last state when the enable pin is de‑asserted, providing a simple method for synchronizing asynchronous signals. Its wide operating voltage range makes it compatible with 5 V logic families as well as newer 3.3 V and 2.5 V platforms, facilitating integration into mixed‑voltage designs. The robust temperature tolerance ensures reliable operation in automotive control units, industrial automation equipment, and outdoor sensor nodes that experience extreme temperature fluctuations. Because the device is supplied in a pack of ten, designers can stock sufficient inventory for large‑scale production runs while keeping per‑unit cost low.
