CD4042BE TI CMOS Quad Clocked D Latch IC DIP-16 Pack of 5

Description

Product Overview

The CD4042BE is a Texas Instruments‑manufactured CMOS quad clocked D‑latch integrated circuit designed for precision timing and data storage in a wide range of electronic systems. Housed in a 16‑lead DIP package, the device offers four independent latch circuits that share a common clock input, enabling synchronized data capture across multiple channels. Each latch provides complementary buffered outputs (Q and Q̅) that maintain signal integrity even under noisy conditions, thanks to a noise margin of up to 2.5 V at a 15 V supply. The IC operates with a maximum input current of just 1 µA at 18 V, and its low‑power TTL‑compatible design ensures minimal quiescent current, making it suitable for battery‑powered and energy‑conscious applications. Fully compliant with JEDEC Tentative Standard No. 13B, the CD4042BE meets rigorous industry specifications for reliability, temperature range, and electrical performance. The product is supplied in a pack of five units, providing designers with a cost‑effective solution for prototyping, production, and maintenance inventories.

Usage

The CD4042BE excels in environments where synchronized data latching is essential. Typical use cases include buffer storage registers in microcontroller interfaces, holding registers for programmable logic controllers, and timing‑critical sections of digital signal processing chains. Its common‑clock architecture simplifies board layout, reducing the number of required clock lines and minimizing routing complexity in high‑density designs. Engineers often integrate the device into industrial control panels, scientific instrumentation, and communication equipment where reliable state retention during clock transitions is mandatory. The IC’s robust input tolerance and low leakage make it a preferred choice for automotive diagnostics, aerospace telemetry, and medical device circuitry that must operate flawlessly across a broad temperature spectrum. By providing both Q and Q̅ outputs, the CD4042BE enables designers to implement complementary logic without additional inversion stages, saving board space and power.
