UPD8243HC Description

Short technical summary and product information.

The NEC UPD8243HC is a 4-bit input/output (I/O) expander IC. Manufactured by NEC, this component is designed to extend the I/O capabilities of microcontrollers and other digital systems.

 

Key specifications include a nominal operating voltage range of 4.75V to 5.25V, making it suitable for standard logic level applications. It provides 20 I/O pins, offering significant expansion potential. The device operates across a temperature range of 0°C to 70°C.

 

Packaged in a DIP (Dual In-line Package), the UPD8243HC is designed for through-hole mounting. Its 24 terminals facilitate easy integration into breadboard or PCB designs. This component is useful in applications requiring additional digital input or output lines beyond the native capabilities of a primary processor.

 

While compliance data like RoHS, REACH, and MSL are listed, they are currently unverified and should be treated with low confidence. Further verification from official documentation is recommended.
