IDT74FCT257ATSOG8

Overview

The IDT74FCT257ATSOG8 is a quad 2-input multiplexer from the 74FCT logic series, manufactured by Renesas Electronics. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an industrial temperature range of -40°C to +85°C. The component utilizes a 16-pin QSOP package for surface-mount installation. It features non-inverting logic functionality with three-state outputs, designed for high-speed data selection applications in digital systems.

Feature Summary

• Provides four independent 2-to-1 data selection paths
• Supports three-state output control for bus isolation
• Compatible with standard CMOS and TTL logic levels

Applications

• Data routing in mixed-signal systems
• Address decoding circuits
• Signal path selection in instrumentation

Procurement Notes

Verify the specific suffix 'ATSOG8' against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 16-QSOP form factor. Cross-reference the manufacturer part number with authorized distributors to avoid obsolete or counterfeit components.

Selection Notes

Select this component when a compact quad multiplexer solution is required for 5V logic environments. The FCT series offers faster switching speeds compared to standard 74LS equivalents. Confirm that the QSOP package dimensions fit the available board space and thermal requirements of the target application design.

Part Context

This device belongs to the broader 74FCT family of high-speed CMOS logic devices originally developed by Integrated Device Technology (IDT) and now produced by Renesas Electronics. The 74FCT257 variant specifically addresses multiplexing needs, providing a reliable alternative to older transistor-transistor logic technologies while maintaining pin compatibility with legacy designs.
