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

Typical Application shows a simple application where a physical push button is connected to the

SN74LVC2G241. The push button is in a physical location far enough away from the processor that the input

signal is weak and needs to be redriven. The SN74LVC2G241 acts as a redriver, providing a strong input signal

to the processor with as little as 1 ns of propagation delay.

9.2.1 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, so

routing and load conditions must be considered to prevent ringing.

9.2.2 Detailed Design Procedure

1. Recommended Input Conditions

–

Rise time and fall time specs. See (Δt/ΔV) in Recommended Operating Conditions.

–

Specified high and low levels. See (VIH and VIL) in Recommended Operating Conditions.

–

Inputs are overvoltage tolerant allowing them to go as high as (VI max) in Recommended Operating

Conditions at any valid VCC.

2. Recommend Output Conditions

–

Load currents must not exceed (IO max) per output and must not exceed (Continuous current through VCC

or GND) total current for the part. These limits are located in Absolute Maximum Ratings.

–

Outputs must not be pulled above VCC during normal operation or 5.5 V in high-z state.
