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
The SN74AUP1T17 is a low-power CMOS device that can be used for a multitude of buffer type functions where the input is slow or noisy. The inputs are 5.5-V tolerant allowing it to translate down to VCC. In addition, the device can translate a signal up to VCC when the input is at least VT+ (max).
9.2 Typical Application
This application is for a low-cost oscillator. The SN74AUP1T17 at the output cleans up the noise from the clock generator so that it can be used in the system.

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 should be considered to prevent ringing.
9.2.2 Detailed Design Procedure
- Recommended Input Conditions
- Specified high and low levels. See (VT+ and VT-) in the Recommended Operating Conditions table.
- Inputs are overvoltage tolerant allowing them to go as high as (VI max) in the Recommended Operating Conditions table at any valid VCC .
- Recommend 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.
- Outputs should not be pulled above VCC.
