SN54/74HCT CMOS Logic Family Applications and Restrictions
PDF, 102 Kb, 档案已发布: May 1, 1996
The TI SN54/74HCT family of CMOS devices is a subgroup of the SN74HC series with the HCT circuitry modified to meet the interfacing requirements of TTL outputs to high-speed CMOS inputs. The HCT devices can be driven by the TTL circuits directly without additional components. This document describes the TTL/HC interface the operating voltages circuit noise and power consumption.
