Overview
The TL16C554AIPNG4 is an enhanced quadruple version of the TL16C550C asynchronous-communications element (ACE) produced by Texas Instruments. This component integrates four improved TL16C550C ACEs along with steering logic, enabling it to perform serial-to-parallel and parallel-to-serial conversions for data characters. Each channel can operate independently, and the CPU can read the complete status of each channel at any time, including the type and condition of the operation and any error conditions encountered.
