HD3-6408-9Z

Encoders, Decoders, Converters Overview

The HD3-6408-9Z is a CMOS Universal Asynchronous Receiver Transmitter (UART) manufactured by Renesas Electronics. It operates on a single +5V supply and features CMOS/TTL compatible inputs. The device supports programmable word lengths of 5, 6, 7, or 8 bits, with selectable odd or even parity. Stop bits can be configured as one, two, or one-and-a-half bits for 5-bit codes. The receiver converts serial start, data, parity, and stop bits, while the transmitter adds these bits automatically to parallel data.

Encoders, Decoders, Converters Procurement Notes

Verify the specific suffix '9Z' against official Renesas documentation to confirm RoHS compliance and anneal status. Ensure the package type matches the required SOICW footprint. Confirm lead availability through authorized distributors as this component may have limited stock due to its specialized nature.

Encoders, Decoders, Converters Selection Notes

Select this UART when interfacing microprocessors to asynchronous serial channels requiring low power consumption. Consider the operating frequency requirements; the standard version supports up to 2.0MHz, while military-grade variants may support higher speeds. Ensure the system voltage aligns with the single +5V requirement.

Encoders, Decoders, Converters Part Context

This component belongs to the HD-6400 series of UARTs, designed for reliable serial communication in embedded systems. It utilizes advanced scaled SAJI IV CMOS process technology to reduce power dissipation significantly compared to older NMOS counterparts, making it suitable for battery-operated or heat-sensitive applications.

Encoders, Decoders, Converters Replacement Considerations

The HD3-6402R is a related variant within the same family, offering an 8.0MHz operating frequency. Verify pin compatibility and electrical specifications before substitution. No direct cross-manufacturer equivalents are confirmed in public datasheets without detailed parameter matching.
