FSTD3306MTC

Signal Switches, Multiplexers, Decoders Overview

The FSTD3306MTC is a 2-bit low-power bus switch with level shifting capabilities, manufactured by onsemi. It features ultra-high-speed CMOS FET technology and TTL-compatible active LOW control inputs. The device provides enhanced level-shifting circuitry to facilitate interfacing between 5V and 3.3V logic levels. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to +85°C. The component is housed in an 8-lead Thin Shrink Small Outline Package (TSSOP).

Signal Switches, Multiplexers, Decoders Feature Summary

• Enhanced level-shifting circuitry facilitates seamless interfacing between 5V and 3.3V systems.
• Ultra-high-speed CMOS FET architecture ensures minimal propagation delay through the switch.
• TTL-compatible active LOW control inputs provide robust signal handling.
• Control inputs are over-voltage tolerant, allowing operation up to 5.5V independent of VCC.

Signal Switches, Multiplexers, Decoders Applications

• Interfacing 5V logic devices with 3.3V logic devices.
• High-speed data bus switching applications.
• Portable electronic equipment requiring low power consumption.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific package variant when ordering, as the FSTD3306MTC designation corresponds to the tube packing method in the TSSOP-8 configuration. Confirm that the application environment remains within the specified -40°C to +85°C operating temperature range. Ensure unused logic inputs are held HIGH or LOW to prevent floating states during operation.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for designs requiring bidirectional data transfer between different voltage domains without external level shifters. The integrated level-shifting feature simplifies board layout compared to discrete solutions. Consider the low on-resistance characteristics for maintaining signal integrity in high-frequency bus applications.

Signal Switches, Multiplexers, Decoders Part Context

This component belongs to the family of low-power bus switches designed for portable electronics. It serves as a bridge for connecting buses operating at different voltage levels, such as legacy 5V peripherals to modern 3.3V processors. The device integrates two independent switches controlled by separate enable inputs.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check datasheets for equivalent 2-bit bus switches with level shifting from other manufacturers. Verify pin compatibility and electrical specifications, particularly on-resistance and voltage tolerance, before substituting.
