CD74HCT139M96G4

Overview

The CD74HCT139M96G4 is a high-speed CMOS logic device manufactured by Texas Instruments. It functions as a dual 2-to-4-line decoder/demultiplexer housed in a 16-pin SOIC package. The component 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. It features independent decoding for two channels, each utilizing two address inputs to select one of four outputs. The device includes active-low enable inputs to control operation.

Feature Summary

• Dual independent 2-to-4 line decoding capability
• Active-low output selection with enable control
• High-speed CMOS technology for low power consumption

Applications

• Address decoding in microprocessor systems
• Data distribution in digital communication circuits
• Memory chip select generation

Procurement Notes

Verify the specific suffix G4 indicates lead-free and RoHS compliance status according to Texas Instruments documentation. Confirm the package marking matches the 16-SOIC physical dimensions. Ensure the ordering part number aligns with the required tape and reel or cut tape packaging format specified in the manufacturer's catalog.

Selection Notes

Select this component when dual independent decoding is required within a single package. The HCT series ensures compatibility with standard TTL logic levels while maintaining CMOS noise immunity. Verify that the 4.5 V to 5.5 V supply voltage range meets the system power requirements and that the -55°C to +125°C temperature range covers the intended operational environment.

Part Context

This device belongs to the CD74HCT family of high-speed CMOS logic integrated circuits. The family provides performance comparable to the older 74HC series but with input characteristics compatible with standard TTL logic levels. The M96 suffix typically denotes a specific package variant or manufacturing site code within the Texas Instruments product line.

Replacement Considerations

Compatible substitutes include the CD74HCT139M96 and CD74HCT139M96E4. These parts share identical logical functionality and pinout configurations. Verify that any replacement maintains the same package type and electrical specifications before integration.
