詳細說明
Meet your differential line driver needs with the SN65LBC172A16DWR. Whether you're working with TIA/EIA-485 (RS-485), TIA/EIA-422 (RS-422), or ISO 8482 applications, this device has you covered. Its 3-state outputs and optimized design allow for balanced multipoint bus transmission at signaling rates up to 30 million bits per second. Additionally, the device features current limiting and thermal-shutdown circuitry, making it suitable for high-speed multipoint data transmission applications, especially in noisy environments. The use of LinBiCMOS™ technology ensures low power consumption and robustness, while the G and G inputs provide driver enable control using either positive or negative logic. When disabled or powered off, the driver outputs present a high-impedance to the bus, reducing system loading. With operating temperature ranges of 0°C to 70°C or -40°C to 85°C, the SN65LBC172A16DWR is a versatile and reliable choice for your application

常見問題解答
What is SN65LBC172A16DWR?
The SN65LBC172A16DWR is a 3.3-V, low-power, data transceiver designed to meet TIA/EIA-485 and TIA/EIA-422-B standards for balanced communication. It is ideal for applications requiring high-speed and half-duplex data transmission over long cable lengths, such as industrial automation, instrumentation, and point-of-sale terminals.
How Does SN65LBC172A16DWR Work?
The SN65LBC172A16DWR works by converting TTL/CMOS-level signals into differential TIA/EIA-485 and TIA/EIA-422-B signals for robust data communication. It features a high common-mode voltage range and a 1/5 unit load capability, allowing multiple transceivers to be connected on the bus. The transceiver is designed to withstand harsh electrical environments, making it suitable for industrial applications.
How Many Pins does SN65LBC172A16DWR have and What are the Functions of the Pinout Configuration?
The SN65LBC172A16DWR is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:
- A, B: Differential bus connection pins.
- GND: Ground pin.
- DE, /RE: Driver output enable and receiver output enable pins.
- VCC: Power supply pin.
- /RE, /DE: Active-low input control pins for receiver and driver, respectively.
- Y, Z: Receiver and driver output pins.
What are the Pros and Cons of SN65LBC172A16DWR?
