CY74FCT138ATSOCT

Overview

The CY74FCT138ATSOCT 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 a propagation delay of 6 ns. The device is housed in an SSOP-16 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides one-hot decoding for eight distinct output lines based on three address inputs.
• Features active-low outputs suitable for direct interfacing with logic circuits.

Applications

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

Procurement Notes

Verify the specific suffix 'TSOCT' against the manufacturer's current datasheet to confirm the exact tape-and-reel quantity and moisture sensitivity level. Ensure the SSOP-16 footprint matches the design layout, as pin configurations can vary between similar FCT series packages.

Selection Notes

Select this component when a fast, low-power 1-of-8 decoder is required for 5V logic applications. The FCT series offers compatibility with TTL inputs while maintaining CMOS power consumption levels. Consider the SSOP-16 package constraints regarding board space and thermal dissipation during the design phase.

Part Context

This part belongs to the CY74FCT138T family of decoders and demultiplexers. It is designed for high-speed digital applications requiring precise signal routing. The device integrates advanced CMOS technology to ensure reliable operation across industrial temperature ranges.

Replacement Considerations

Check for CY74FCT138ATQCT or other FCT138 variants with compatible pinouts and electrical specifications. Verify that any substitute maintains the same SSOP-16 package dimensions and voltage requirements.
