10 Application and Implementation

10.1 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

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.
