FST16862MTDX

Overview

The FST16862MTDX is a high-speed CMOS TTL-compatible bus switch providing 20 bits of switching capability. It operates on a single supply voltage ranging from 4V to 5.5V and features an operating temperature range of -40°C to 85°C. The device is housed in a 48-TFSOP package with a width of 6.10mm. It contains five independent circuits, each configured as a 1x1 switch, totaling 20 bits. The low on-resistance allows inputs to be driven directly from standard logic gates.

Feature Summary

• Provides 20 bits of high-speed CMOS bus switching
• TTL-compatible input/output functionality
• Low on-resistance for direct drive from standard logic

Applications

• High-speed data bus switching applications
• Portable battery-powered equipment
• Consumer electronics requiring low power consumption

Procurement Notes

Verify the component status as obsolete or new original stock depending on the supplier source. Confirm the package type matches the required 48-TFSOP specification. Ensure the manufacturer is identified correctly as Fairchild Semiconductor or ON Semiconductor, as ownership transitions may affect documentation availability. Check RoHS compliance status if required for specific manufacturing standards.

Selection Notes

Select this component when 20-bit synchronous bus switching is required within a compact surface-mount footprint. The 4V to 5.5V supply range suits systems operating at standard 5V logic levels. Consider the 48-TFSOP package dimensions for PCB layout constraints. Verify that the TTL compatibility meets the interface requirements of the connected logic devices.

Part Context

This part belongs to the FST series of bus switches designed by Fairchild Semiconductor, now part of ON Semiconductor. The series focuses on high-speed, low-power switching solutions for digital signal paths. The FST16862 specifically offers a higher bit count compared to smaller variants, making it suitable for wider data buses in compact electronic designs.

Replacement Considerations

Check for equivalent parts within the FST16xxx series from ON Semiconductor. Verify pinout compatibility before substituting with other 48-pin bus switches. Ensure the replacement supports the same 4V-5.5V operating voltage and temperature range.
