10 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.

10.1 Application Information

SN74LVC00A 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 3.3 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

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

10.2.2 Detailed Design Procedure

1. Recommended Input Conditions

–

Rise time and fall time specs: See (

Δt/ΔV) in the Recommended Operating Conditions, SN74LVC00A

table.

2. Recommend Output Conditions

–

Load currents should not exceed 25 mA per output and 50 mA total for the part.

–

Outputs should not be pulled above 5.5 V.
