9 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.

9.1 Application Information

SN74LVC244A is a high drive CMOS device that can be used for a multitude of bus interface type applications

making it ideal for down translation.

9.2 Typical Application

Figure 4. Application Schematic

9.2.1 Design Requirements

This device uses CMOS technology and has balanced output drive. Avoid bus contention because it can drive

currents in excess of maximum limits. The high drive will also create fast edges into light loads, so consider

routing and load conditions to prevent ringing.
