SN74LV138ATPWT

Overview

The SN74LV138ATPWT is a 3-to-8 line decoder/demultiplexer from Texas Instruments' LV logic series. It features three binary inputs and eight active-low outputs, housed in a 16-TSSOP surface-mount package. The device operates on a single power supply ranging from 4.5 V to 5.5 V. It exhibits a propagation delay of 13 ns and supports output drive currents of 12 mA for both high and low states. The component functions reliably within an ambient temperature range of -40°C to +125°C.

Feature Summary

• Provides decoding or demultiplexing functionality with three binary address inputs controlling eight distinct active-low outputs.
• Incorporates two active-low enable inputs and one active-high enable input to manage device operation states.
• Delivers robust output drive capability suitable for interfacing with various digital loads.

Applications

• Address decoding in embedded systems
• Demultiplexing data streams in communication interfaces
• Chip select generation in memory architectures

Procurement Notes

Verify the specific suffix 'TPWT' corresponds to the TSSOP-16 package and tape-and-reel shipping configuration. Confirm RoHS compliance status and moisture sensitivity level requirements against current datasheet specifications before integration into production workflows.

Selection Notes

Select this component when a 5V-compatible logic family is required for address decoding applications. Ensure the design accommodates the specified 4.5V to 5.5V operating voltage range and thermal constraints associated with the industrial temperature grade.

Part Context
