CY74FCT138CTSOC

Overview

The CY74FCT138CTSOC is a high-speed CMOS 1-of-8 decoder manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and features three enable inputs for flexible control. The device utilizes an SSOP-16 surface-mount package and supports operation across an industrial temperature range from -40°C to +85°C. Designed for the FCT logic series, it provides low power consumption and fast propagation delays suitable for demanding digital applications.

Feature Summary

• Provides one-hot decoding functionality with eight mutually exclusive outputs
• Includes three independent enable inputs for precise signal gating
• Utilizes CMOS technology for low static power dissipation

Applications

• Address decoding in microprocessor-based systems
• Memory chip select generation
• Control signal routing in industrial automation

Procurement Notes

Verify the specific suffix 'CSOC' against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing board layouts requiring SSOP-16 footprints. Confirm RoHS compliance status through current manufacturer datasheets before finalizing procurement orders.

Selection Notes

Select this component when a single input must be decoded into eight distinct output lines with active-low states. Consider the three enable pins for system-wide or conditional activation requirements. Verify that the operating voltage aligns with the 5V logic family standards required by the target circuit design.
