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

There are many situations in which a device needs to be initialized or held off for a short time at system turn-on. This application of the SN74AUP1G17 utilizes the delay created in an RC circuit to hold a line low for a short time when the system is first started, then maintains the line high while the system operates. The SN74AUP1G17 is ideal for this application because it must be tied directly to the primary supply for correct operation and is designed to draw minimal supply current during operation.

9.2 Typical Application

9.2.1 Design Requirements

This 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 drive strength also creates fast edges into light loads, so routing and load conditions should be considered to prevent ringing.

9.2.2 Detailed Design Procedure

  1. Recommended Input Conditions:
  2. Recommended Output Conditions:
    • Load currents should not exceed (IO max) per output and should not exceed (continuous current through VCC or GND) total current for the part. These limits are located in the Absolute Maximum Ratings table.
