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 cir [ ... ]
