HD9P6409-9Z

Specialized ICS Overview

The HD9P6409-9Z is a Manchester Encoder/Decoder manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 1 MHz. The device is housed in a 20-SOIC surface-mount package with dimensions of 7.50 mm width. It functions as a high-speed, low-power logic IC designed for serial data communication applications.

Specialized ICS Feature Summary

• Manchester Encoding and Decoding: Converts Nonreturn-to-Zero (NRZ) code into Manchester code and vice versa.
• High Data Rate: Supports static operation up to 1 Mbps.
• Low Power Consumption: Typical power dissipation is 50 mW at +5V.
• Digital PLL Clock Recovery: Reconstructs input signals with recovered clock to minimize noise effects.

Specialized ICS Applications

• Security systems
• Environmental control systems
• Serial data links

Specialized ICS Procurement Notes

Verify the specific ordering suffix when purchasing. The 'Z' suffix indicates RoHS compliance. Ensure the required packaging format matches the part number variant; the base model typically ships in tubes, while other suffixes may indicate reel packaging. Confirm availability through authorized distributors as stock levels fluctuate.

Specialized ICS Selection Notes

Select this component for applications requiring Manchester coding with NRZ interface compatibility. It is suitable for environments needing DC component elimination and improved noise immunity. Verify that the operating temperature range (-40°C to +85°C) meets system requirements and that the 20-SOIC package fits the PCB layout constraints.

Specialized ICS Part Context

This device belongs to the HD9P6409 series of encoders and decoders. It is functionally similar to the HD-6408 but operates with slightly different principles. Both are designed for serial data communication where data accuracy is critical, such as in magnetic tape recording or fiber optic communication contexts.

Specialized ICS Replacement Considerations

The HD-6408 is a related Intersil/Renesas Manchester encoder-decoder with similar functionality. Verify pinout compatibility and specific operational differences before substitution. No direct public substitute part numbers are confirmed in the provided documentation.
