HD9P6409-9

Specialized ICS Overview

The Intersil HD9P6409-9 is a CMOS Manchester Encoder/Decoder designed for serial data communication applications. 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 ensures low bit error rates through features such as a digital PLL clock recovery system and an on-chip oscillator. It consumes approximately 50 mW at +5V. The component is housed in a 20-SOIC package with a width of 7.50 mm, suitable for surface-mount installation.

Specialized ICS Feature Summary

• CMOS Manchester Encoder/Decoder with independent encoder and decoder operation
• Supports converter mode (NRZ to Manchester) and repeater mode
• Digital PLL clock recovery for high noise immunity
• Low operating power consumption of 50 mW typical at +5V

Specialized ICS Applications

• Security systems
• Environmental control systems
• Serial data links

Specialized ICS Procurement Notes

Verify the specific suffix '9' against official Renesas or Intersil documentation to confirm if it denotes a specific temperature grade, lead finish, or packaging variant distinct from the standard HD9P6409. Confirm RoHS compliance status and moisture sensitivity level prior to ordering, as these parameters can vary by manufacturing site and date code.

Specialized ICS Selection Notes

Select this component when designing serial communication interfaces requiring Manchester coding for DC balance and clock recovery. Ensure the design environment accommodates the 4.5 V to 5.5 V supply voltage range. Verify that the 20-SOIC footprint matches the PCB layout constraints and that the 1 MHz maximum data rate meets the system throughput requirements.

Specialized ICS Part Context

The HD9P6409 belongs to the HD-6409 series of high-speed, low-power Manchester encoders and decoders manufactured using self-aligned silicon gate technology. It is part of the broader portfolio of logic ICs used for converting Nonreturn-to-Zero (NRZ) codes to Manchester codes, facilitating reliable data transmission in noisy environments.

Specialized ICS Replacement Considerations

The HD-6408 is a related device in the same family offering similar Manchester encoding/decoding capabilities. Verify pin compatibility and functional equivalence before substitution. Other generic Manchester encoders may require additional external components for clock recovery.
