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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
