CD74HC85E Rizees 16-DIP Comparator IC 8µA Quiescent Current 33ns Delay

Description

Product Overview

The CD74HC85E comparator from Rizees is engineered to deliver high‑speed, accurate magnitude comparison across four bits, making it a versatile component for a wide range of digital logic and signal‑conditioning applications. Housed in a compact 16‑DIP (0.300″, 7.62mm) package, the device occupies minimal board space while providing robust electrical performance. Its low quiescent current of 8 µA reduces power consumption, which is especially valuable in battery‑powered or energy‑sensitive designs. The part features a maximum propagation delay of 33 ns at a 6 V supply and 50 pF load, ensuring rapid response times for time‑critical circuits. Operating temperature spans from –55 °C to 125 °C, guaranteeing reliable operation in harsh industrial environments and scientific instrumentation.

Usage

Designed for industrial electrical and signal‑processing contexts, the CD74HC85E excels in applications such as digital comparators, level‑shifters, and logic‑level translation modules. Its four‑bit magnitude comparison capability enables designers to implement priority encoders, threshold detectors, and multi‑channel analog‑to‑digital conversion front‑ends. The component’s wide temperature range and low power draw make it suitable for automotive control units, aerospace telemetry, and laboratory equipment where stability and efficiency are paramount. Engineers working on microcontroller interfacing will appreciate the device’s ability to provide clean, fast logic transitions, reducing the need for additional buffering stages.

FAQ

What is the maximum operating voltage for the CD74HC85E?

The comparator is rated for a supply voltage up to 6 V, which covers most standard digital logic levels used in industrial and scientific equipment.

Can the CD74HC85E be used in automotive applications?

Yes, its temperature range of –55 °C to 125 °C and low power consumption make it well‑suited for automotive control modules and sensor interfaces.

How does the quiescent current affect my design?

A quiescent current of 8 µA means the device draws very little power when idle, helping to extend battery life and reduce overall system power budgets.

Is the CD74HC85E compatible with standard microcontroller I/O levels?

Absolutely. The comparator’s input and output thresholds are designed to interface directly with common 3.3 V and 5 V microcontroller logic levels without additional level‑shifting components.
