74LVX138SJ

Signal Switches, Multiplexers, Decoders Overview

The Fairchild Semiconductor 74LVX138SJ is a low-voltage 1-of-8 decoder/demultiplexer. It operates within a supply voltage range of 2 V to 3.6 V and supports surface-mount installation in a 16-SOP package. The device functions as a single circuit with three address inputs and eight outputs, designed for high-speed bipolar memory chip select address decoding applications.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the current status of the 74LVX138SJ, as it is listed as obsolete by some distributors. Confirm availability through authorized channels or check for equivalent active components from onsemi if long-term supply is required. Ensure the specific SOP-16 package matches the design constraints.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a low-voltage 1-of-8 decoder is needed for memory addressing. The 2 V to 3.6 V operating range makes it suitable for 3.3 V logic systems. Consider the 16-SOP package size for PCB layout compatibility. Verify that the 4 mA output drive capability meets the load requirements of the connected circuits.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the LVX series of low-voltage logic devices. It is functionally similar to other 74LVX138 variants but may differ in packaging or manufacturer origin. Fairchild Semiconductor was acquired by onsemi, which continues to produce related parts in the 74LVX138 family.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check for equivalents such as the onsemi 74LVX138MTCX or other 74LVX138 variants. Ensure pinout and electrical characteristics match before substitution.
