INTEGRATED CIRCUITS DATA SHEET FAMILY SPECIFICATIONS HCMOS family characteristics March 1988 File under Integrated Circuits, IC06 Philips Semiconductors HCMOS family characteristics GENERAL These family specifications cover the common electrical ratings and characteristics of the entire HCMOS 74HC/HCT/HCU family, unless otherwise specified in the individual device data sheet. INTRODUCTION The 74HC/HCT/HCU high-speed Si-gate CMOS logic family combines the low power advantages of the HE4000B family with the high speed and drive capability of the low power Schottky TTL (LSTTL). The family will have the same pin-out as the 74 series and provide the same circuit functions. In these families are included several HE4000B family circuits which do not have TTL counterparts, and some special circuits. The basic family of buffered devices, designated as XX74HCXXXXX, will operate at CMOS input logic levels for high noise immunity, negligible typical quiescent supply and input current. It is operated from a power supply of 2 to 6 V. FAMILY SPECIFICATIONS A subset of the family, designated as XX74HCTXXXXX, with the same features and functions as the “HC-types”, will operate at standard TTL power supply voltage (5 V ± 10%) and logic input levels (0.8 to 2.0 V) for use as pin-to-pin compatible CMOS replacements to reduce power consumption without loss of speed. These types are also suitable for converted switching from TTL to CMOS. Another subset, the XX74HCUXXXXX, consists of single-stage unbuffered CMOS compatible devices for application in RC or crystal controlled oscillators and other types of feedback circuits which operate in the linear mode. HANDLING MOS DEVICES Inputs and outputs are protected against electrostatic effects in a wide variety of device-handling situations. However, to be totally safe, it is desirable to take handling precautions into account (see also “HANDLING PRECAUTIONS”).
