TL16C754BFNG4

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C754BFNG4 is a quad universal asynchronous receiver-transmitter (UART) integrated circuit manufactured by Texas Instruments. It features four independent UART channels, each equipped with a 64-byte FIFO buffer to enhance data throughput and reduce processor intervention. The device supports baud rates up to 3 Mbps when driven by a 1.8432 MHz clock source. It operates within a supply voltage range of 2.7 V to 5.5 V and is housed in a 64-pin TSSOP package. The component includes hardware auto-flow control capabilities and is designed for industrial temperature ranges.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates four independent UART channels with dedicated 64-byte receive and transmit FIFOs for efficient data handling.
• Supports high-speed asynchronous communication with baud rates reaching 3 Mbps under standard clock conditions.
• Incorporates hardware auto-flow control logic to manage data flow between the UART and external devices without CPU overhead.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring multiple serial communication ports.
• Embedded controllers managing simultaneous serial data streams.
• Telecommunications equipment utilizing asynchronous interface protocols.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the complete part number including the suffix 'G4' to confirm lead-free and RoHS compliance status. Confirm the specific temperature grade associated with the 'B' suffix against the official datasheet before procurement. Ensure the TSSOP-64 footprint matches the target PCB design constraints.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four independent serial interfaces are required on a single chip. Compare FIFO depth requirements against simpler dual-channel alternatives if fewer ports suffice. Verify that the 2.7V to 5.5V operating voltage aligns with the system power rails. Consider pin count and package size relative to available board space.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the TL16C75x family of quad UARTs from Texas Instruments. It serves as a multi-port serial expansion solution for microcontrollers lacking sufficient built-in UART peripherals. The device replaces discrete UART chips or simpler dual-channel variants in complex embedded designs.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct replacements include other TL16C754 variants with different packages or temperature grades, such as TL16C754BIPNR or TL16C754BPWR. Cross-reference pinouts and electrical characteristics carefully when substituting with non-Texas Instruments quad UARTs.
