implementation to confirm system functionality.

8.1 Application Information

The SN74LVC126A device is a high-drive, CMOS device that can be used for a multitude of buffer-type

functions. It can produce 24 mA of drive current at 3 V. Therefore, this device is ideal for driving multiple inputs

and for high-speed applications up to 100 MHz. The inputs and outputs are 5.5-V tolerant allowing the device to

translate up to 5.5 V or down to VCC.

8.2.1 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 also creates fast edges into light loads;

therefore, routing and load conditions must be considered to prevent ringing.
