RF803D

Overview

The RF803D is an 8-pin decoder integrated circuit from the RF800 series, designed for remote control and radio telemetry applications. It decodes data streams from compatible RF transmitters to drive three digital outputs (OP1-OP3). The device supports a supply voltage range of 2.5V to 5.5V with typical standby current below 1µA. It features an 'easy learn' pairing function allowing up to 15 transmitter pairings per receiver. Outputs can be configured as momentary or latching via the SD/ML pin. A serial data output provides encoder status, including battery level and input states, at 9.6K baud.

Feature Summary

• Supports up to 15 unique transmitter pairings with easy learn/erase functionality
• Provides 3 configurable digital outputs (OP1-OP3) with momentary or latching modes
• Outputs serial data stream containing encoder serial number, input states, and battery status
• Compatible with FireFly, FireBlade, and 205 series transmitters

Applications

• Remote control systems
• Radio telemetry
• RFID applications

Procurement Notes

Verify package type availability; datasheet lists both SOIC and PDIP options while local fields specify Tube packaging. Confirm that the specific ordering suffix corresponds to the required physical footprint before procurement. Ensure power supply stability meets the <10mV ripple requirement for reliable operation.

Selection Notes

Select the RF803D when a decoder solution with multiple configurable outputs and serial monitoring is required. Choose this over the RF803E, which functions as the encoder counterpart. Consider the SD/ML pin configuration requirements for momentary versus latching output behavior during schematic design.

Part Context

The RF803D belongs to the RF800 series chipset, which includes the RF803E encoder. This family allows for flexible system design where any RF800 part can be used with off-the-shelf counterparts from the manufacturer. The series utilizes Manchester encoded data protocols for reliable radio links.

Replacement Considerations

No direct replacement part numbers are documented in the provided source material. Custom versions of the RF803E/RF803D chipset may be available for OEM applications through the manufacturer's sales department.
