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

SN74LV541A is a low-drive CMOS device that can be used for a multitude of bus interface type applications

where the data needs to be retained or latched. It can produce 16 mA of drive current at 5 V, making it Ideal for

driving multiple outputs and good for low noise applications. The inputs are 5.5-V tolerant allowing it to translate

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.

10.2.2 Detailed Design Procedure

1. Recommended Input Conditions

–

For rise time and fall time specifications, see

Δt/ΔV in the Recommended Operating Conditions table.
