9 Applications and Implementation

9.1 Application Information

The SN74LVC374A 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 32 mA of drive current at 3.3 V; therefore, making it ideal for driving multiple outputs and good for high speed applications up to 100 MHz. The inputs are 5.5-V tolerant allowing it to translate down to VCC.

9.2 Typical Application

9.2.1 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 so routing and load conditions should be considered to prevent ringing.

9.2.2 Detailed Design Procedure

  1. Recommended Input conditions
  2. Recommend output conditions
    • Load currents should not exceed 25 mA per output and 50 mA total for the part.
    • Outputs should not be pulled above VCC.
