CD74HCT138M96G4

Signal Switches, Multiplexers, Decoders Overview

The CD74HCT138M96G4 is a high-speed CMOS logic decoder manufactured by Texas Instruments. It functions as a 3-to-8 line decoder/demultiplexer housed in a 16-SOIC surface-mount package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55°C to +125°C. Key electrical characteristics include a propagation delay of 48 ns, a maximum static current of 8 uA, and output drive capabilities of 4 mA for both high and low states.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides three binary selection inputs to decode signals into one of eight active-low outputs.
• Includes two active-low enable inputs and one active-high enable input to facilitate cascading applications.
• Features high-speed silicon gate CMOS technology offering performance comparable to low-power Schottky TTL.

Signal Switches, Multiplexers, Decoders Applications

• Memory address decoding

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the SOIC-16 package dimensions match the target PCB footprint. Ensure the 4.5V to 5.5V supply voltage requirements align with the system design. Check that the -55°C to +125°C industrial temperature rating meets environmental specifications.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a single 3-to-8 decoder is required with TTL-compatible input levels. The HCT series ensures compatibility with standard 5V logic systems while maintaining CMOS power efficiency. Consider the 16-SOIC package for surface-mount assembly constraints. Verify that the 48 ns propagation delay satisfies the timing requirements of the target application circuit.

Signal Switches, Multiplexers, Decoders Part Context
