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

The SN74LVC2G66 can be used in any situation where an Dual SPST switch would be used and a solid-state,

voltage controlled version is preferred.

9.2 Typical Application

Figure 11. Typical Application Schematic

9.2.1 Design Requirements

The SN74LVC2G66 allows on/off control of analog and digital signals with a digital control signal. All input

signals should remain between 0 V and VCC for optimal operation.

9.2.2 Detailed Design Procedure

1. Recommended Input Conditions:

–

For rise time and fall time specifications, see Δt/Δv in the Recommended Operating Conditions table.

–

For specified high and low levels, see VIH and VIL in the Recommended Operating Conditions table.

–

Inputs and outputs are overvoltage tolerant allowing them to go as high as 5.5 V at any valid VCC.

2. Recommended Output Conditions:

–

Load currents should not exceed ±50 mA.

3. Frequency Selection Criterion:

–

Maximum frequency tested is 150 MHz.

–

Added trace resistance or capacitance can reduce maximum frequency capability; use layout practices as

directed in Layout.
