FSTUD32450GX_NL

Overview

The FSTUD32450GX is a configurable bus switch manufactured by Fairchild Semiconductor. It provides high-speed CMOS and TTL-compatible switching capabilities with configurable bit widths ranging from 4-bit to 40-bit. The device features selectable level shifting, low on-resistance for minimal propagation delay, and zero bounce in flow-through mode. Control inputs are compatible with TTL levels, and the component is packaged in a plastic Fine-Pitch Ball Grid Array (FBGA).

Feature Summary

• Configurable bus switching architecture supporting variable bit widths.
• Selectable voltage level shifting functionality.
• Low on-resistance enabling minimal signal propagation delay.

Applications

• High-speed data bus interconnects
• Voltage domain translation between logic families
• Signal routing in embedded systems

Procurement Notes

Verify the specific suffix GX_NL against official Fairchild documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating temperatures and signal integrity standards before integration into final designs.

Selection Notes

Select this component when designing systems requiring flexible bus width configuration and level shifting. Evaluate the FBGA package constraints and thermal requirements relative to the target application environment.

Part Context

This part belongs to the Universal Bus Switch family, which includes variants like the FSTD32450. These components are designed for high-speed digital signal routing where low distortion and configurable connectivity are critical.

Replacement Considerations

Consult official substitution guides for equivalents such as the FSTD32450 or FSTUD32450. Verify pinout and electrical parameter alignment before replacing.
