9 Application and Implementation
9.1 Application Information
The SN74AHC1G32 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 except voltages to 5.5 V at any valid VCC making it ideal for down
9.2 Typical Application
VCC 3.3 V - 5 V Regulated

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 (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
• Recommended 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
