6N134TXV

Overview

The Broadcom Limited 6N134TXV is a high-speed optocoupler featuring two independent channels within a hermetically sealed ceramic package. It supports data rates up to 10 Mb/s with a current transfer ratio of 100%. The device utilizes an open collector output configuration and provides 1500 Vdc isolation voltage. Key electrical parameters include a forward current of 20 mA, a forward voltage of 1.5 V, and a rise time of 90 ns. Maximum power dissipation is rated at 85 mW, with an operating temperature range spanning from -40°C to +85°C.

Feature Summary

• Dual-channel architecture for simultaneous signal transmission
• Hermetically sealed construction ensuring environmental stability
• High common-mode transient immunity (CMTI) of 1 kV/µs
• Schottky-clamped open collector outputs for fast switching

Applications

• Industrial communication bus interfaces
• Data acquisition systems requiring galvanic isolation
• Power supply feedback control loops
• Signal isolation in noisy electromagnetic environments

Procurement Notes

Verify the specific suffix 'TXV' to confirm the hermetically sealed ceramic package variant, as standard plastic packages differ significantly in thermal and isolation performance. Ensure compatibility with existing PCB footprints designed for dual-channel DIP configurations. Cross-reference datasheet specifications for CMTI ratings against system noise requirements before finalizing procurement orders.

Selection Notes

Select this component when dual-channel isolation is required within a single footprint. The hermetic seal makes it suitable for harsh environments where moisture or gas ingress could compromise standard plastic optocouplers. Compare the 10 Mb/s speed against slower alternatives if bandwidth is critical. Verify that the 1500 Vdc isolation rating meets the safety standards of the target application circuit.

Part Context

The 6N134 series belongs to Broadcom's family of high-speed logic output optocouplers. Unlike single-channel variants such as the 6N137, the 6N134 integrates two isolated channels. The TXV suffix specifically denotes the hermetically sealed ceramic version, distinguishing it from non-hermetic plastic counterparts like the 6N134T. This packaging offers superior reliability for aerospace or industrial applications.

Replacement Considerations

Direct pin-compatible replacements may be limited due to the specific hermetic package requirement. Non-hermetic equivalents like the 6N134T offer similar electrical characteristics but lack the sealed enclosure. Single-channel devices such as the 6N137 require two units to achieve equivalent functionality, increasing board space.
