74LCX138MTCX

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74LCX138MTCX is a low-voltage CMOS 3-to-8 line decoder/demultiplexer from the 74LCX series. It operates within a supply voltage range of 2.0 V to 3.6 V and features five enable inputs for flexible system control. The device utilizes a 16-pin TSSOP surface-mount package with a pin pitch of 0.65 mm. It supports industrial operating temperatures from -40°C to +85°C and includes ESD protection exceeding 2000V (HBM). The component provides high noise immunity and low power consumption, making it suitable for portable battery-powered applications.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'MTCX' confirms the 16-pin TSSOP package and reel packaging configuration. Ensure the revision level matches the target design requirements. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Validate that the supplier source provides genuine onsemi products to avoid counterfeit risks.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a low-voltage 3-to-8 decoder is required with multiple enable controls. It serves as a direct replacement for legacy 74HC138 or 74LVC138 parts where lower supply voltages are necessary. Consider its 3.6 V maximum rating against system rail availability. Evaluate the TSSOP-16 footprint compatibility during PCB layout planning.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic devices manufactured by onsemi. The LCX series bridges the performance gap between older HC and newer LVC technologies, offering fast switching speeds at reduced voltages. The 138 designation specifically identifies the 3-to-8 decoder topology within this extensive logic portfolio.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Cross-reference with 74LCX138MX for identical functionality in an SOIC-16 package. Verify pinout compatibility with 74HC138 or 74LVC138 variants if migrating from higher voltage designs.
