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 SN74LVC1G19 device is a 1-of-2 decoder/demultiplexer. This device decodes the 1 bit address on input A

produce 24 mA of drive current at 3.3 V making it ideal for driving multiple outputs.

9.2 Typical Application

Figure 5. Typical Application Diagram

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. Outputs can be combined to produce higher drive but the

high drive will also create faster edges into light loads so routing and load conditions should be considered to

prevent ringing.

9.2.2 Detailed Design Procedure

1. Recommended Input Conditions:

–

For rise time and fall time specifications, see (

Δt/ΔV) in Recommended Operating Conditions table.

–

–

2. Recommend Output Conditions:

–

Load currents must not exceed 50 mA per output and 100 mA total for the part.

–

Series resistors on the output may be used if the user desires to slow the output edge signal or limit the

output current.
