ST16C2450IJ44

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C2450IJ44 is a dual universal asynchronous receiver/transmitter (UART) integrated circuit manufactured by Sipex. It features two independent serial I/O channels capable of data transmission rates up to 0.1875 MBps. The device operates on a CMOS process and supports asynchronous communication protocols with NRZ data encoding. It is housed in a 44-pin plastic J-Lead Surface Mount Package (SOP). The component includes an internal clock generator and programmable baud rate generators for each channel, allowing flexible interface configurations without external timing components.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'IJ44' to confirm the 44-pin surface mount package variant. Ensure compatibility with the required operating voltage range and temperature specifications for the target application environment. Cross-reference the manufacturer part number against current distributor catalogs to confirm availability and authenticity from authorized sources.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual independent serial interfaces are required in a compact surface-mount form factor. Compare pin counts and package dimensions against board layout constraints. Verify that the maximum data rate of 0.1875 MBps meets the throughput requirements of the connected devices. Consider thermal dissipation characteristics if operating at high ambient temperatures.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This device belongs to the ST16C450 family of dual UARTs, designed to replace older TTL-level serial controllers with more flexible CMOS alternatives. The 'I' designation typically indicates industrial temperature range operation, while 'J44' specifies the 44-lead SOP package. It serves as a direct upgrade path for legacy designs requiring enhanced integration and lower power usage.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for pin-compatible alternatives within the same family, such as the ST16C450 series variants. Verify electrical parameter equivalence, particularly supply voltage ranges and logic levels. Confirm package footprint compatibility before substituting to avoid PCB redesign requirements.
