FSTD16450MTD

Overview

The FSTD16450MTD is a 20-bit configurable bus switch manufactured by Fairchild Semiconductor, now part of onsemi. It operates on a single power supply within the voltage range of 4V to 5.5V. The device features ten independent circuits configured as 1:1 switches, providing flexible signal routing capabilities. It is housed in a 56-TSSOP surface-mount package with a width of 6.10mm. The component supports an operating temperature range from -40°C to 85°C and is classified under logic signal switches and multiplexers.

Feature Summary

• Configurable 20-bit architecture allowing flexible signal path management
• Single-supply operation compatible with standard logic levels
• Ten independent 1:1 switching circuits for precise control

Applications

• Data protocol conversion systems
• Negative voltage design protection circuits
• High-performance bus interface applications

Procurement Notes

Verify current availability status as this product may be discontinued or subject to last-time buy restrictions. Confirm that the manufacturer designation aligns with onsemi standards following corporate acquisitions. Ensure the specific suffix matches required packaging and environmental compliance specifications before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring high-density signal switching within a limited footprint. The 56-pin TSSOP package offers space efficiency for complex board layouts. Consider the 4V to 5.5V operating range to ensure compatibility with existing system power rails and logic voltage levels without additional level shifting requirements.

Part Context

This device belongs to the FST series of high-speed bus switches developed by Fairchild Semiconductor. The series is known for low on-resistance and fast switching speeds suitable for digital signal processing. The FSTD16450 variant specifically addresses the need for configurable data paths in communication and computing hardware architectures.

Replacement Considerations

Check for direct pin-compatible substitutes within the same FST family. Verify electrical characteristics such as on-resistance and propagation delay against alternative components. Ensure any replacement maintains the 56-TSSOP package dimensions and thermal performance requirements.
