Philips HCMOS Family Characteristics Data Handbook
Summary
The Philips 74HC/HCT/HCU HCMOS family specifications document provides comprehensive electrical characteristics and operating parameters for this high-speed Si-gate CMOS logic family. Covers three device series: buffered 74HC (2-6V, CMOS input levels), TTL-compatible 74HCT (5V, TTL input levels, pin-to-pin compatible LSTTL replacements), and unbuffered 74HCU (for RC/crystal oscillators and linear feedback circuits). Includes voltage ratings, current specifications, timing parameters, noise immun

Frequently Asked Questions
What is the recommended operating voltage range for 74HC/HCT devices?
The typical DC supply voltage ranges from 5.0V (min.) to 6.0V (max.).
How are the 74HCU/74HC combined with HE4000B family circuits?
They combine low power advantages of feedback circuits with high speed and drive capability, suitable for oscillators.
What is the maximum specified operating temperature?
For typical operation, the ambient temperature range is -40°C to +85°C. For specific devices, it can reach -40°C to +125°C.
