PC16550DV/NOPB

Overview

The PC16550DV/NOPB is a single-channel Universal Asynchronous Receiver/Transmitter (UART) manufactured by Texas Instruments. It supports data rates up to 1.5 MBd and operates with a typical supply voltage of 5 V. The device features 16-byte transmit and receive FIFOs, along with counters for both buffers. It is housed in a 40-pin MDIP package designed for through-hole mounting. Physical dimensions are 52.58 mm in length, 13.97 mm in width, and 4.19 mm in height. The operational temperature range spans from 0°C to +70°C.

Feature Summary

Integrated 16-byte transmit and receive FIFOs with dedicated counters
Supports high-speed serial communication up to 1.5 MBd
Compatible with standard 5 V logic systems

Applications

Serial communication controller interfaces
Industrial control system I/O expansion
Embedded hardware development boards

Procurement Notes

Verify the component authenticity by checking the manufacturer marking against official Texas Instruments documentation. Confirm the specific suffix NOPB indicates lead-free compliance. Ensure the MDIP package type matches the required through-hole mounting specifications for the target PCB design before finalizing procurement.

Selection Notes

Select this UART when a single channel with moderate speed requirements is needed. The 16-byte FIFOs help manage data throughput efficiently. Consider the physical size constraints of the 40-pin MDIP package. Verify that the 0°C to +70°C operating range meets the environmental conditions of the intended application environment.

Part Context

This component belongs to the PC16550 family of UARTs. It serves as a functional equivalent to standard 16550-compatible devices but includes enhanced FIFO capabilities. The DV suffix typically denotes a specific package variant within the broader product line. It is commonly used in legacy system upgrades or new designs requiring reliable asynchronous serial connectivity.
