Package  
description  
The TL16PIR552 has a dual-channel universal asynchronous receiver/transmitter (UART). The UART is similar  
to the TL16C550C. The device serves two serial input/output ports simultaneously in microcomputer or  
microprocessor-based systems. Each channel performs serial-to-parallel conversion on data characters  
received from peripheral devices or modems and parallel-to-serial conversion on data characters transmitted  
by the CPU. The complete status of each channel of the dual UART can be read by the CPU at any time during  
functional operation. The information obtained includes the type and condition of the transfer operation being  
performed and the error condition.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

testing of all parameters.
