FIN1531MTCX

Overview

The FIN1531MTCX is a 5V LVDS 4-Bit High Speed Differential Driver manufactured by onsemi. It translates 5V TTL/CMOS signal levels to LVDS levels with a typical differential output swing of 350 mV. The device supports data rates greater than 400 Mbps and operates within a supply voltage range of 4.5V to 5.5V. Key electrical parameters include a maximum propagation delay of 2.0 ns, a maximum differential pulse skew of 400 ps, and a power supply current of up to 26 mA under load. It features power-off protection and meets the TIA/EIA-644 LVDS standard. The component is housed in a 16-lead TSSOP package.

Feature Summary

• Translates 5V TTL/CMOS inputs to LVDS outputs for high-speed interconnects
• Provides low EMI and ultra-low power dissipation at high frequencies
• Includes power-off protection to prevent bus contention during shutdown
• Pin-compatible with equivalent RS-422 and PECL devices

Applications

• High-speed transfer of clock signals
• High-speed transfer of data signals
• Low voltage differential signaling (LVDS) interconnects

Procurement Notes

Verify the specific ordering suffix 'X' indicates tape and reel packaging when sourcing this component. Confirm the manufacturer origin, as the datasheet references Fairchild Semiconductor, which was acquired by onsemi. Ensure the procurement matches the TSSOP-16 package variant required for the design. Check for RoHS compliance status if environmental regulations apply to the target application.

Selection Notes

Select the FIN1531MTCX when a 5V supply is available and TTL/CMOS to LVDS translation is required. This driver is suitable for applications needing less than 2.0 ns propagation delay. Consider pairing it with the companion FIN1532 receiver or other compatible LVDS receivers. Verify that the 400ps skew specification meets the system timing requirements for multi-channel synchronization.

Part Context

The FIN1531 belongs to the LVDS driver family designed for high-speed serial communication. It serves as the transmitting counterpart to receivers like the FIN1532. The device is part of a broader portfolio of interface solutions aimed at reducing electromagnetic interference while maintaining high data throughput in digital systems.

Replacement Considerations

Direct pin-compatible replacements may include other 5V LVDS quad drivers from various manufacturers. Ensure any substitute maintains the 5V operating voltage and LVDS output standards. Verify that the replacement device offers similar propagation delay and skew characteristics to avoid timing violations in the existing circuit design.
