DS3886AVFN

Overview

The DS3886AVFN is a full-duplex RS-232 transceiver manufactured by Rochester Electronics, LLC. It supports data rates up to 1 Mb/s and operates with supply voltages of 3 V and 5.5 V. The device features BTL (Balanced Transmitter Line) drivers and includes 9-bit latching functionality for data integrity. It provides ESD protection rated at 4 kV and 15 kV. The component is available in various packages including SOIC-16, QFN-16, and PDIP-16, supporting both surface mount and through-hole installation styles.

Feature Summary

• Full-duplex RS-232 communication capability
• 9-bit latching mechanism for enhanced data reliability
• Balanced Transmitter Line (BTL) driver configuration
• Integrated electrostatic discharge (ESD) protection

Applications

• Industrial control systems requiring reliable serial communication
• Test and measurement equipment interfaces
• Embedded systems utilizing RS-232 protocols
• Legacy system maintenance and replacement scenarios

Procurement Notes

Verify the specific package variant and date code upon order confirmation, as Rochester Electronics supplies lifecycle components. Confirm that the received unit matches the requested pinout and electrical specifications. Request documentation regarding manufacturing origin and testing standards to ensure compliance with project requirements. Validate part authenticity through official channels provided by the supplier.

Selection Notes

Select this component when a robust RS-232 transceiver with latching capabilities is required for industrial or embedded applications. Consider the availability of multiple package options for flexible PCB layout designs. Evaluate the need for BTL drivers if balanced transmission line performance is critical. Ensure compatibility with existing 3 V or 5.5 V power domains within the target system architecture.

Part Context

Rochester Electronics specializes in authorized continuing source solutions for end-of-life and obsolete semiconductors. The DS3886AVFN represents a lifecycle management product, often serving as a replacement for original manufacturer parts no longer in active production. This approach ensures supply chain continuity for critical infrastructure and long-term industrial deployments.

Replacement Considerations

Consult official datasheets to verify pin-to-pin compatibility with original design specifications. Confirm that voltage levels and signal integrity requirements are met by the Rochester Electronics version. Review mechanical dimensions to ensure fit within existing enclosures or PCB footprints.
