TL16C752CIRHB

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C752CIRHB is a dual universal asynchronous receiver-transmitter (UART) integrated circuit manufactured by Texas Instruments. It features two independent UART channels, each equipped with a 64-byte FIFO buffer to enhance data throughput and reduce processor overhead. The device supports high-speed serial communication with a maximum data rate of 3 Mbps. It operates within a wide supply voltage range of 1.62 V to 5.5 V, ensuring compatibility with various logic levels. The component is housed in a 32-VQFN package measuring 5x5 mm, designed for surface-mount assembly. Key protocol support includes RS-485, and it integrates automatic flow control, IrDA encoding/decoding, modem control signals, and false start bit detection capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the exact suffix against official Texas Instruments documentation, as variations such as CIPFBRG4 or CIRHBR indicate specific packaging or revision differences. Confirm moisture sensitivity level and reflow soldering profile requirements prior to assembly. Ensure the source provides valid RoHS compliance statements and check for any product change notifications that may affect long-term availability or pinout consistency.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual independent UART channels with substantial FIFO depth are required. The wide voltage range makes it suitable for both 3.3 V and 5 V systems. Consider the 32-VQFN package size for space-constrained designs. Verify that the 3 Mbps speed meets application needs and that IrDA or RS-485 features align with interface requirements.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the TL16C752 family of dual UART controllers from Texas Instruments. It is an evolution of earlier single-channel UARTs, offering increased parallelism through dual channels and larger buffers. The family is commonly used in legacy system replacements and modern embedded designs requiring robust serial connectivity without external FIFO controllers.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C752CIRHBRG4 is listed as a parameter-equivalent substitute. Verify pin compatibility and electrical specifications before substitution. Other family members like TL16C752B may offer similar functionality but differ in FIFO size or speed.
