FST3383WM

Overview

The FST3383WM is a 10-bit low-power bus exchange switch manufactured by Fairchild Semiconductor. It provides two sets of high-speed CMOS TTL-compatible bus switches within a single package. The device features a typical on-resistance (Ron) of 4 Ω and a maximum delay through the switch of less than 0.25 ns. It operates with nearly zero standby current and ensures no circuit bounce during operation.

Feature Summary

• Provides high-speed CMOS and TTL-compatible signal switching capabilities
• Features low on-resistance to maintain signal integrity across connections
• Designed for low power consumption with nearly zero standby current
• Eliminates circuit bounce to ensure stable signal transitions

Applications

• High-speed data bus exchange systems
• Signal conditioning in digital logic circuits
• Low-power portable electronic devices requiring efficient bus management

Procurement Notes

Verify the specific datasheet version from Fairchild Semiconductor or authorized distributors to confirm pinout compatibility and electrical characteristics. Ensure the component meets RoHS compliance requirements if mandated by your project specifications. Cross-reference the part number FST3383WM with official manufacturer documentation to validate performance parameters before integration.

Selection Notes

Select this component when designing systems that require bidirectional bus switching with minimal signal degradation. The low on-resistance and high speed make it suitable for applications demanding fast data transfer rates. Consider the package type and voltage supply range (4V to 5.5V) to ensure compatibility with the target system's power architecture.

Part Context

This component belongs to the FST series of bus exchange switches, which are designed for high-performance digital applications. The series typically offers configurable switching options and low power consumption. Fairchild Semiconductor, now part of ON Semiconductor, produces these components for use in various consumer and industrial electronics requiring reliable signal routing.

Replacement Considerations

The FST3384 is a related 10-bit bus switch variant from the same manufacturer. Verify pin-to-pin compatibility and electrical specifications before substituting. Consult official datasheets to ensure functional equivalence in terms of on-resistance, speed, and power consumption.
