Overview
The FST16861MTDX is a dual 10-bit bus driver manufactured by onsemi, formerly Fairchild Semiconductor. It operates within a supply voltage range of 4V to 5.5V and features true outputs. The device is housed in a 48-TSSOP package with dimensions of 6.10mm width. It supports an operating temperature range from -40°C to +85°C. The component is classified as a bus switch with two independent circuits. Moisture Sensitivity Level (MSL) is rated at 2.
Feature Summary
- Dual 10-bit configuration for high-density data routing
- True output logic state preservation
- Surface mount TSSOP-48 packaging for compact integration
Applications
- High-speed data bus switching
- Memory interface buffering
- Parallel data line isolation
Procurement Notes
Verify the manufacturer status carefully, as this part is associated with Rochester Electronics distribution and may be obsolete or end-of-life. Confirm the specific suffix 'X' indicates tape and reel packaging if required for automated assembly. Cross-reference the RoHS compliance status with the current datasheet revision before finalizing procurement plans.
Selection Notes
Select this component when a dual 10-bit bus driver is required for 5V logic systems. Ensure the design accommodates the 48-pin TSSOP footprint and the specified thermal operating range. Verify that the single power supply requirement aligns with the system's voltage rails and that the true output characteristic meets the signal integrity needs.
Part Context
This device belongs to the FST series of fast bus switches. It is designed for applications requiring low on-resistance and high bandwidth. The component serves as a bridge between different logic domains, facilitating efficient data transfer across parallel buses while maintaining signal fidelity in high-speed digital environments.
Replacement Considerations
The SN74CBT16861DGVR from Texas Instruments is listed as a similar substitute. Verify pin compatibility and electrical specifications against the original datasheet before substitution.
