Introduction
The SN75C188DBR is an integrated circuit designed by Texas Instruments for interface applications such as digital and analog data transfer, communication, and control. It is a quad universal asynchronous receiver-transmitter (UART) with digital inputs/outputs (I/O) that has integrated full duplex, bidirectional transmit/receive functions and can drive up to 10 bits with TTL-level user interface compatibility. It is ideally suited for OEMs, developers, and end-users alike in a variety of industries.
Features
The SN75C188DBR has a variety of features which make it useful for interface applications:
- Up to 10 bits of user interface compatibility
- Low power dissipation
- Programmable baud rate
- High-impedance inputs/outputs
- Internal parity generation/checking
- Fully compatible with industry-standard UARTs
- Efficient Input/Output port interface
- Functionally compatible with several industry-standard ICs
- Robust design for high-temperature and EMI operation
Applications
The SN75C188DBR is suitable for a range of interface applications, including:
- Industrial control systems
- Data communication and networking
- Robotics and automation
- Automotive control systems
- Consumer electronics
- Military applications
Working Principle
The SN75C188DBR utilizes the UART protocol to implement a bidirectional, full duplex data communications system. When used to receive data, the device will listen for a request, upon which it will convert the incoming signal from asynchronous to a synchronous signal by adding mandatory framing, that is by adding start and stop signals. This allows for accurate transfer of data from one device to another. When used as a transmitter, the device will take the asynchronous data stream and convert it into a synchronous signal, adding mandatory framing and transmitting the signal to the receiving end. Both the receiver and transmitter have their respective logic circuits to handle the signal. The device also implements an internal parity generator to ensure quality data transmission. When enabled, the parity generation will calculate a parity bit based on the transmitted or received data byte and append it to the byte before it is sent over the bus. When using even parity, the parity bit will be one if the number of ‘1’s in the transmitted/received byte is an even number, and it will be zero if it is an odd number. This ensures that errors in transmission can be detected, as the parity bit won’t match the transmitted/received byte. The SN75C188DBR is also equipped with a variety of features to improve the reliability of data transfer. It features on-chip power monitoring, adaptive biasing, and current-saving Low-power modes. It also includes bus pirate protection, which disables all outputs when no valid voltage is detected on the bus. Moreover, there is also an internal temperature sensor, allowing the device to shut down when the temperature is too high, protecting the device from damage.
Conclusion
The SN75C188DBR is a highly versatile, low-power UART interface IC designed by Texas Instruments. It is ideally suited for OEMs, developers, and end-users alike in a variety of industries, due to its wide range of features and functionalities, including support for 10 bits of user interface compatibility, programmable baud-rate, robust design, and internal parity generation/checking. It is most suitable for industrial control systems, robotics and automation, data communication and networking, automotive control systems, consumer electronics, and military applications.
