Philips FAMILY SPECIFICATIONS Data Manual
Summary
Philips Semiconductors 74HC/HCT/HCU HCMOS family specifications datasheet (March 1988) documenting the complete electrical characteristics and operating parameters for this high-speed Si-gate CMOS logic family. Covers three device series: buffered 74HC (2-6V supply, CMOS input levels, high noise immunity), TTL-compatible 74HCT (5V +/-10%, LSTTL pin-to-pin replacements with reduced power), and unbuffered 74HCU (for RC/crystal oscillators and linear-mode feedback circuits). Includes recommended op

Frequently Asked Questions
What is the maximum operational ambient temperature range?
For 74HC/HCT, the specified operating range is −40 to +85 °C; for 74HCU, it extends up to −40 to +125 °C.
What voltage range should be used when operating the 74HC family?
The family operates from a power supply of 2.0 to 6.0 V DC. The input voltage range is specified as 0 V to 5.5 V.
How are 74HUT/HCT and 74HC combined in the HCMOS family?
They combine low-power advantages of the HE4000B family with the high speed and drive capability characteristic of LSTTL.
What happens to power dissipation (P) at higher temperatures?
For 74HC/HCT/HCU plastic DIL, power dissipation above +70°C must be derated linearly with 12 mW/K.
