Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'MTR' corresponds to the SOP-16 package and tape & reel shipping configuration as defined in the official datasheet order codes table. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure that the operating temperature range of -55°C to +125°C aligns with your environmental specifications before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a 3-to-8 decoding function is required with 5V input tolerance. It is suitable for designs needing low quiescent current and high-speed switching in low voltage environments. Consider the 16-pin SOP package constraints and ensure the application benefits from the provided power-down protection features for robust interface design.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74LVX series of low voltage CMOS logic devices manufactured by STMicroelectronics. It is functionally compatible with the standard 74LS138 series but optimized for lower voltage operation and improved latch-up immunity. The device utilizes sub-micron silicon gate and double-layer metal wiring C2MOS technology for enhanced performance.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct pin and function compatible replacements include other manufacturers' 74LVX238 variants. Verify that any substitute maintains the 5V tolerant input specification and the 2V to 3.6V operating voltage range to ensure circuit compatibility.
