PC16550DN

Overview

The PC16550DN is a single-channel Universal Asynchronous Receiver/Transmitter (UART) manufactured by Texas Instruments. It supports data rates up to 1.5 MBd and operates at a typical supply voltage of 5 V. The device features 16-byte transmit and receive FIFOs with counters, housed in a 40-pin MDIP package for through-hole installation. Physical dimensions are 52.58 mm in length, 13.97 mm in width, and 4.19 mm in height. It functions within an operating temperature range of 0°C to +70°C.

Feature Summary

Integrated 16-byte transmit and receive FIFOs with counters to reduce CPU overhead
Supports asynchronous communication protocols with baud rates up to 1.5 MBd
Compatible with standard 16550 UART software interfaces

Applications

Serial computer interface connections
Modem interface circuits
Industrial serial communication systems

Procurement Notes

Verify the component marking against the official Texas Instruments datasheet for part number PC16550DN/NOPB. Confirm the package type is MDIP and pin count is 40. Ensure the manufacturer identification matches Texas Instruments or its authorized predecessor entities to avoid counterfeit components.

Selection Notes

Select this component when a through-hole UART solution is required for 5V logic systems. It is suitable for designs needing 16-byte FIFO buffering to handle high-speed serial data without excessive CPU intervention. Verify that the 40-pin MDIP footprint fits the PCB layout constraints.

Part Context

This part belongs to the 16550 family of UARTs, widely used for serial communication. The PC prefix typically indicates a specific manufacturing line or revision within the Texas Instruments portfolio. It serves as a drop-in replacement for legacy 16550 designs while offering enhanced FIFO capabilities.

Replacement Considerations

PC16550DN/NOPB is the direct equivalent with lead-free compliance. Other 16550-compatible UARTs from different manufacturers may require pinout verification.
