Overview
The SN74LV139APWT is a dual 2-line to 4-line decoder/demultiplexer from the Texas Instruments 74LV series. It operates on a single power supply ranging from 2V to 5.5V and features active-low enable inputs for simplified cascading or data reception. The device incorporates Ioff circuitry to support partial-power-down mode, preventing damaging current backflow when powered down. Designed for high-speed memory decoders and data-transmission systems, it ensures mixed-mode voltage operation across all ports.
Feature Summary
- Supports mixed-mode voltage operation on all ports
- Incorporates two enable inputs to simplify cascading and/or data reception
- Ioff supports partial-power-down mode operation
Applications
- High-speed memory decoders
- Data-transmission systems
- Partial-power-down applications
Procurement Notes
Verify the specific ordering suffix 'PWR' corresponds to the TSSOP-16 package with tape-and-reel carrier. Confirm RoHS compliance status and lead finish details via the latest TI Package Option Addendum. Ensure the component meets the required operating temperature range of -40°C to 85°C for your application environment.
Selection Notes
Select this component for designs requiring low-voltage operation between 2V and 5.5V. It is suitable for applications needing fully buffered inputs that represent only one normalized load to the driving circuit. Consider its propagation delay characteristics relative to your system's timing requirements at the specific operating voltage.
Part Context
This part belongs to the SN74LV139A family of dual 2-line to 4-line decoders/demultiplexers. It is manufactured by Texas Instruments and is available in multiple packages including SOIC, SSOP, TVSOP, SOP, TSSOP, and VQFN. The PW suffix specifically denotes the Thin-Shrink Small-Outline Package (TSSOP).

FAQ
How does the Ioff feature benefit the SN74LV139APWT?
The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is in a partial-power-down state.
What is the function of the G input pins?
The active-low enable (G) inputs can be used as data lines in demultiplexing applications or to control the output state of each decoder channel.
