FST16232MTD

Overview

The FST16232MTD is a synchronous 16-bit to 32-bit multiplexer/demultiplexer bus switch manufactured by Fairchild Semiconductor. It belongs to the CBT/FST/QS/5C/B series and utilizes CMOS technology with TTL-compatible inputs. The device features one functional unit with sixteen input lines and thirty-two output lines, providing true output polarity. It operates within a supply voltage range of 4 V to 5.5 V, with a nominal voltage of 5 V. The component is supplied as an uncased chip die in a rectangular package form.

Feature Summary

• Enables connection between two separate datapaths without adding propagation delay or generating additional ground bounce noise
• Provides low on-resistance switch connections between ports for efficient signal transmission
• Utilizes synchronous control select pins clocked on the rising edge of the clock signal when the enable pin is low

Applications

• High-speed data routing in digital systems
• Multiplexing multiple data sources onto a single path
• Demultiplexing a single data path into separate outputs

Procurement Notes

Verify that the specific procurement request matches the bare die configuration rather than a standard packaged IC. Confirm the manufacturer origin aligns with Fairchild Semiconductor specifications. Ensure the application environment supports the required 4 V to 5.5 V supply voltage range. Check compatibility with the synchronous control logic requirements involving CLK and CLKEN signals.

Selection Notes

Select this component when designing circuits requiring high-speed synchronous data switching with minimal signal distortion. It is suitable for applications needing to route sixteen input lines to thirty-two output lines efficiently. Consider its CMOS construction and TTL compatibility for integration with standard logic families. Evaluate the need for synchronous control mechanisms using clock edges for precise timing management.

Part Context

This part is part of the FST series of high-speed CMOS bus switches designed for performance-critical digital applications. It shares functional similarities with other devices in the CBT/FST/QS/5C/B family but offers specific 16-to-32 bit routing capabilities. The synchronous nature distinguishes it from asynchronous alternatives, allowing for controlled data flow based on clock signals.
