  CMOS Power Consumption and CPD Calculation (Rev. B)
  PDF, 89 Kb, Revision: B, File published: Jun 1, 1997
  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

  Designing With Logic (Rev. C)
  PDF, 186 Kb, Revision: C, File published: Jun 1, 1997
  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

  Using High Speed CMOS and Advanced CMOS in Systems With Multiple Vcc
  PDF, 43 Kb, File published: Apr 1, 1996
  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

  SN54/74HCT CMOS Logic Family Applications and Restrictions
  PDF, 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.
