UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes
This component is officially discontinued and no longer manufactured by Texas Instruments. Procurement is limited to existing stock held by distributors or third-party suppliers. Buyers should verify the authenticity and condition of available units carefully, as availability is unpredictable and subject to market fluctuations without guaranteed future supply.
UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes
Designers seeking a direct replacement must consider that this part is end-of-life. The manufacturer recommends the TL16C750EPFBR as an alternative. Engineers should evaluate pin compatibility, electrical specifications, and software driver support when migrating from the TL16C451FN to newer UART interface solutions to ensure system continuity.
UARTs (Universal Asynchronous Receiver Transmitter) Part Context
The TL16C451FN belongs to the TL16C45x family of asynchronous communication elements. This series provides standard UART functionality with additional modem control lines. The specific 'FN' suffix indicates the 68-pin PLCC package variant. The device serves as a dedicated interface chip for converting parallel data to serial format and vice versa in embedded systems.
UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations
Texas Instruments recommends the TL16C750EPFBR as a manufacturer-approved substitute. Verify functional equivalence regarding channel count, FIFO depth, and pinout compatibility before integration into existing designs.
