DS91C176TMA/NOPB

The DS91C176TMA/NOPB is a high-speed, low-power, differential line transceiver designed for use in various communication applications, particularly in the context of RS-485 and RS-422 standards. Manufactured by Texas Instruments, this device is optimized for data transmission over long distances and in electrically noisy environments, making it suitable for industrial automation, process control, and other data communication systems.

Key Features:

1. Differential Signaling: The DS91C176TMA/NOPB utilizes differential signaling to enhance noise immunity and reduce electromagnetic interference (EMI). This is particularly beneficial in environments where signal integrity is critical.

2. Data Rate: The transceiver supports high data rates, typically up to 10 Mbps, allowing for fast communication between devices.

3. Low Power Consumption: Designed for efficiency, the device operates with low power consumption, making it suitable for battery-powered applications and helping to reduce overall system power requirements.

4. Wide Supply Voltage Range: The device can operate over a wide supply voltage range, typically from 3.0V to 5.5V, providing flexibility in various system designs.

5. Temperature Range: The DS91C176TMA/NOPB is rated for operation over an extended temperature range, making it suitable for industrial applications where temperature fluctuations can occur.

6. Integrated Features: The transceiver includes built-in features such as thermal shutdown protection and short-circuit protection, enhancing reliability and robustness in demanding environments.
