74LV139BQ,115

Signal Switches, Multiplexers, Decoders Overview

The 74LV139BQ,115 is a low-voltage Si-gate CMOS dual 2-to-4 line decoder/demultiplexer in a DHVQFN16 package. It operates from 1.0 V to 5.5 V and accepts TTL input levels between 2.7 V and 3.6 V. The device contains two independent decoders with active LOW enables and mutually exclusive active LOW outputs. Propagation delay ranges from 10 ns to 39 ns depending on voltage and temperature. It supports ambient temperatures from -40 °C to +125 °C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix against the manufacturer's current database to confirm package type and availability status. Confirm RoHS compliance details directly with the supplier documentation. Check for any product change notifications that may affect pinout or electrical characteristics prior to final design approval.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when dual independent decoding is required within a single package footprint. Ensure the supply voltage remains within the 1.0 V to 5.5 V range. Verify that the DHVQFN16 thermal pad connection requirements are met by the PCB layout. Consider propagation delay specifications relative to the system clock speed.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices. It is functionally and pin-compatible with 74HC139 and 74HCT139 variants. The DHVQFN16 package provides a compact surface-mount solution suitable for space-constrained designs requiring thermal enhancement through the exposed pad.
