9 Application and Implementation

9.1 Application Information

The SN74LVC1G32 device is a high drive CMOS device that can be used for implementing OR logic 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

9.2 Typical Application

9.2.1 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.

9.2.2 Detailed Design Procedure
