10 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.

10.1 Application Information

The SN74LVCH16373A is a high-drive CMOS device that can be used for a multitude of bus interface type applications where the data needs to be retained or latched. It can produce 24 mA of drive current at 3.3 V; therefore making it ideal for driving multiple outputs. This device is also good for high-speed applications up to 100 MHz. The inputs are 5.5-V tolerant allowing translation down to VCC.

10.2 Typical Application

10.2.1 Design Requirements

This device uses CMOS technology and has balanced output drive. Care should be taken to avoid bus contention because it can drive currents that would exceed maximum limits. The high drive will also create fast edges into light loads; therefore, routing and load conditions should be considered to prevent ringing.

10.2.2 Detailed Design Procedure

  1. Recommended input conditions
  2. Recommend output conditions
    • Load currents should not exceed 50 mA per output and 100 mA total for the part.
    • Outputs should not be pulled above VCC.
