9 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality.

9.1 Application Information

A common application for AND gates is their use in power sequencing. Power sequencing is often employed in applications that require a processor or other delicate device with specific voltage timing requirements in order to protect the device from malfunctioning. Using the SN74AHC1G08 to verify that the processor has turned on can protect it from any harmful signals.

9.2 Typical Application

9.2.1 Design Requirements

The SN74AHC1G08 device uses CMOS technology and has balanced output drive. Take care to avoid bus contention because it can drive currents that would exceed maximum limits.

The SN74AHC1G08 allows switching control of analog and digital signals with a digital control signal. All input signals should remain as close to either 0 V or VCC as possible for optimal operation.

9.2.2 Detailed Design Procedure

  1. Recommended input conditions:
  2. Recommended output conditions:
    • Load currents should not exceed ±50 mA.
  3. Frequency selection criterion:
    • The effects of frequency upon the device's power consumption should be studied in CMOS Power Consumption and CPD Calculation, SCAA035.
    • Added trace resistance and capacitance can reduce maximum frequency capability; follow the layout practices listed in the Layout section.
