NJU3730R-TE1

Serializers, Deserializers Overview

The NJU3730R-TE1 is an I2C to parallel converter IC manufactured by Nisshinbo Micro Devices. It converts serial I2C data into three bits of parallel output data (DO0, DO1, DO2). The device supports selectable slave addresses via the SEL terminal, allowing up to three units on a single bus. Operating voltage ranges from 2.4V to 5.5V with a maximum clock frequency of 100 kHz. It utilizes CMOS technology and is housed in a VSP8 package.

Serializers, Deserializers Procurement Notes

Verify the specific ordering suffix TE1 against the manufacturer's current documentation to confirm reel packaging specifications. Ensure the selected component matches the required VSP8 package outline and electrical characteristics defined in the official datasheet before finalizing procurement orders.

Serializers, Deserializers Selection Notes

Select this component when an I2C interface requires expansion into multiple discrete parallel control lines. Verify that the system voltage falls within the 2.4V to 5.5V operating range. Confirm that the SEL pin configuration aligns with the desired slave address to prevent bus conflicts if multiple converters are used.

Serializers, Deserializers Part Context

This part belongs to the NJU3730 series of specialized interface ICs designed for serial-to-parallel conversion. It serves as a bridge between microcontrollers using I2C protocols and peripheral devices requiring parallel input signals, facilitating simplified wiring in audio and video equipment architectures.

Serializers, Deserializers Replacement Considerations

Consult the official Nisshinbo Micro Devices cross-reference documentation for verified substitute part numbers. Do not assume functional compatibility with other I2C converters without verifying pinout, voltage ratings, and timing specifications.

Serializers, Deserializers FAQ

How many NJU3730 devices can be connected to the same I2C bus?

A maximum of three NJU3730 devices can be connected to the same I2C bus, distinguished by selecting different slave addresses via the SEL terminal.

What determines the slave address of the NJU3730?

The slave address is determined by the logic level or state of the SEL terminal: Low Level sets one address, Open sets another, and High Level sets the third.

Is the NJU3730 capable of transmitting data back to the master?

No, the NJU3730 is a receive-only slave device and does not support general call addresses or data transmission back to the master.
