9 Application and Implementation

9.1 Application Information

The SN74LVC3G34 is a high-drive CMOS device that can be used as a buffer with a high output drive, such as an LED application. It can produce 24 mA of drive current at 3.3 V, 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. Take care 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 must be considered to prevent ringing.

9.2.2 Detailed Design Procedure

  1. Recommended Input Conditions
  2. Recommended Output Conditions
    • Load currents must not exceed (IO max) per output and must not exceed (Continuous current through VCC or GND) total current for the part. These limits are located in the Recommended Operating Conditions table.
    • Outputs must not be pulled above VCC under normal operating conditions.
