9 Application and Implementation
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 Typical Application
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
– Specified high and low levels. See (V
– Inputs are overvoltage tolerant allowing them to go as high as (V
Conditions
at any valid V
2. Recommend Output Conditions
– Load currents must not exceed (I
or GND) total current for the part. These limits are located in
– Outputs must not be pulled above V
