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. A Bergeron anal

The Input/Output Buffer Information Specification (IBIS) also known as ANSI/EIA-656 has become widely accepted among electronic design automation (EDA) vendors semiconductor vendors and system designers as the format for digital electrical interface data. Because IBIS models do not reveal proprietary internal processes or architectural information semiconductor vendors? support for IBIS con

Forty-eight-pin TSSOP components that were packaged using Texas Instruments (TI) standard packing methodology were subjected to electrical discharges between 0.5 and 20 kV as generated by an IEC ESD simulator to determine the level of ISD protection provided by the packing materials. The testing included trays tape and reel and magazines. Additional units were subjected to the same discharge

Data sheets which usually give information on device behavior only under recommended operating conditions may only partially answer engineering questions that arise during the development of systems using logic devices. However information is frequently needed regarding the behavior of the device outside the conditions in the data sheet. Such questions might be:?How does a bus driver behave w

Reduction of power consumption makes a device more reliable. The need for devices that consume a minimum amount of power was a major driving force behind the development of CMOS technologies. As a result CMOS devices are best known for low power consumption. However for minimizing the power requirements of a board or a system simply knowing that CMOS devices may use less power than equivale

Though low power consumption is a feature of CMOS devices sometimes this feature does not meet a designer?s system power supply constraints. Therefore a partial system power down or multiple Vcc supplies are used to meet the needs of the system. This document shows electrostatic discharge protection circuits. It also provides circuit and bus driver examples of partial system power down and curren
