TPT7742F-SSAR

Overview

The TPT7742F-SSAR is a high-performance four-channel digital isolator from 3PEAK, designed for robust signal transmission across isolation barriers. It features a 3750-Vrms isolation rating per UL 1577 when housed in the SOP16 or QSOP16 package. The device supports data rates up to 150Mbps and offers a common-mode transient immunity (CMTI) of 150kV/µs. Operating within a wide temperature range of −40°C to +125°C, it ensures reliable performance in demanding environments.

Feature Summary

• Provides four independent digital isolation channels for efficient signal routing
• Delivers high common-mode transient immunity to maintain signal integrity under noise
• Supports high-speed data transmission with low propagation delay characteristics

Applications

• Industrial automation systems requiring galvanic isolation
• Automotive electronic control units (ECUs)
• Communication interfaces such as RS-485 and CAN networks

Procurement Notes

Verify the specific suffix SSAR confirms the QSOP16 package type and tape-and-reel delivery format. Ensure the procurement documentation explicitly states the 3750-Vrms UL 1577 rating appropriate for the selected package variant. Cross-reference the manufacturer's latest datasheet to confirm compliance with current safety standards and operating temperature ranges before finalizing orders.

Selection Notes

Select this component when four isolated channels are required within a compact footprint. The 150Mbps data rate suits moderate-speed industrial protocols. Consider the 150kV/µs CMTI for noisy environments. Compare against the TPT7740 series if different channel configurations or higher voltage ratings in WSOP16 packages are needed for specific application constraints.

Part Context

This part belongs to the TPT774x family of digital isolators from 3PEAK, which utilizes proprietary isolation IP technology. The family includes variants like TPT7740 and TPT7741, offering flexibility in channel directionality. These devices are engineered for automotive and industrial sectors, emphasizing reliability, low power consumption, and compliance with stringent international safety certifications.

Replacement Considerations

Direct substitutes include other TPT774x variants such as TPT7740F-SSAR or TPT7741F-SSAR, depending on the required input-output directionality. Verify pin compatibility and isolation voltage ratings match the original design requirements before substitution.
