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 SN74LV02A is a Low drive CMOS device that can be used for a multitude of bus interface type applications where output ringing is a concern. The low drive and slow edge rates will minimize overshoot and undershoot on the outputs. The inputs can accept voltages to 5.5 V at any valid VCC making it Ideal for down translation.

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

10.2.2 Detailed Design Procedure

  1. Recommended Input Conditions
    • For specified High and low levels, see VIH and VIL in the Recommended Operating Conditions table.
    • Inputs are overvoltage tolerant allowing them to go as high as 5.5 V at any valid VCC.
  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.
