Product Details
HD9P6409-9Z - CMOS Manchester Encoder/Decoder
HD9P6409-9Z from Renesas Electronics is a 1-Mbps Manchester encoder/decoder for synchronous serial links, supplied in a 20-lead wide SOIC package.
Technical details follow the Renesas exact-part page and HD-6409 data sheet; stock and price observations follow the exact DigiKey listing.
Overview
The HD-6409 is a CMOS Manchester encoder-decoder (MED) that can convert nonreturn-to-zero (NRZ) serial data to Manchester code and recover NRZ data from a Manchester stream. In converter mode it supports a serial line with clock recovery and no DC component; repeater mode reconstructs received Manchester data using its digital phase-locked loop. The device is intended for links where reliable timing recovery and noise tolerance matter.
Key Advantages
Combines NRZ-to-Manchester encoding and Manchester-to-NRZ decoding in one IC.
A digital phase-locked loop recovers timing from the received Manchester stream.
Converter and repeater modes support link endpoints and regenerated links.
The exact -9Z option is specified from −40 C to +85 C.
Feature Summary
The -9Z ordering grade is specified for up to 1 Mbps operation.
Independent encoder and decoder blocks can be used in serial-link designs.
The coded stream has no DC component, allowing transformer-coupled link designs where properly engineered.
Renesas describes approximately 50 mW at the maximum 1-Mbps rate under stated conditions; verify the electrical table for design limits.
Package & Footprint
The exact HD9P6409-9Z is a 20-lead wide SOIC device, identified by Renesas as SOICW / M20.3 and shipped in tubes. The catalog's dimension-qualified package entry normalizes to 20-SOIC; DigiKey describes a 0.295-inch (7.50-mm) wide 20-SOIC case. Use the current Renesas M20.3 drawing and the board assembly rules for final land-pattern dimensions and moisture handling.

Pin Functions
Functional grouping only. Confirm the numbered 20-lead top-view pinout and signal polarities in the Renesas HD-6409 data sheet before board layout.

Replacement Considerations
No direct internal replacement has been verified for this exact order code. The reel-suffixed HD9P6409-9Z96 is an ordering/packaging variant in the Renesas data sheet, but it is not asserted here as an in-stock or automatically interchangeable catalog product. For any alternative, verify the full order code, package drawing, data-rate grade, operating temperature, interface timing, and procurement status before qualification.
Manufacturer Information
Renesas lists HD9P6409-9Z as an active member of its HD-6409 Manchester encoder-decoder family. The exact-part page describes a 20-lead SOICW tube option. Renesas and DigiKey inventory displays are snapshots and can differ; use a current distributor quote to confirm stock, lead time, and order terms before purchasing.
Applications
Encodes and decodes synchronous Manchester serial streams with recovered clock timing.
Reconstructs incoming Manchester signaling when configured in repeater mode.
The zero-DC Manchester waveform can suit appropriately designed isolation or magnetic-coupling links.
Quality & Authenticity
Match the full HD9P6409-9Z marking and Renesas documentation to the tube label, lot records, and 20-lead SOICW package. Confirm the ordered temperature and 1-Mbps grade and follow MSL 3 handling and reflow guidance. The tape-and-reel -9Z96 suffix should not be silently substituted in purchase documentation.
FAQ
What does HD9P6409-9Z convert?
It converts NRZ data to Manchester code and decodes Manchester input back to NRZ in converter mode.
Can it operate as a repeater?
Yes. Renesas describes a repeater mode that reconstructs the Manchester stream using recovered timing.
What is the orderable package?
The -9Z tube option is a 20-lead wide SOIC, normalized in this catalog as 20-SOIC.
Is this page ready to publish?
No. The required local package JPG is missing.
Engineering Notice
Use the current Renesas HD-6409 data sheet for pin numbers, logic levels, timing, electrical limits, and reset/clock configuration. Validate transformer or line coupling in the complete link, and recheck distributor availability and price at the time of purchase.
