Application Notes
- Selecting the Right Texas Instruments Signal SwitchPDF, 769 Kb, File published: Sep 7, 2001
Texas Instruments offers a wide variety of electronic switches (digital analog bilateral bilateral analog) in a variety of families including CBT CBTLV HC LV and LVC. Depending on the application the right solution may be an analog switch that passes digital signals or vice versa. This application report summarizes the various switching technologies and provides considerations for choosi - SN54/74HCT CMOS Logic Family Applications and RestrictionsPDF, 102 Kb, File published: 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.
