ADM1485JRZ-REEL

The ADM1485JRZ-REEL is a high-speed, low-power differential line transceiver designed for high-speed, bidirectional data communication on multi-drop bus transmission lines. Manufactured by Analog Devices Inc. (ADI), this device is fully compliant with the EIA RS-485 and RS-422 standards, making it suitable for a wide range of applications that require balanced data transmission.

Key Features and Specifications:

1. Compliance:
   • Compliant with EIA RS-485 and RS-422 standards.
2. Data Rate:
   • Supports data rates of up to 30 Mbps, enabling high-speed data communication.
3. Power Supply:
   • Operates on a single +5V power supply, providing low power consumption.
4. Differential Line Driver and Receiver:
   • Incorporates both a differential line driver and a differential line receiver.
   • Both the driver and receiver can be independently enabled, with a tri-state output when disabled.
5. High Impedance Output:
   • The driver output enters a high impedance state during fault conditions or when disabled, minimizing load effects on the bus.
6. Thermal Shutdown Protection:
   • Features thermal shutdown protection to prevent excessive power dissipation due to bus contention or output short circuits.
7. Bus Common-Mode Range:
   • Maintains high impedance driver output over a bus common-mode voltage range of -7V to +12V.
8. Receiver with Auto-Fault Function:
   • The receiver includes an auto-fault function that produces a logic high output state when inputs are disconnected (floating).
9. Propagation Delays:
   • Driver propagation delay: 10 ns (typical).
   • Receiver propagation delay: 25 ns (typical).
10. Packaging:
    • Available in an 8-pin DIL/SOIC package, suitable for both commercial and industrial temperature ranges.
11. ESD Protection:
    • All inputs and outputs are protected against ESD (electrostatic discharge).
12. BiCMOS Technology:
    • Fabricated using advanced BiCMOS technology, which combines the low power consumption of CMOS with the fast switching speeds of bipolar transistors.
13. Short-Circuit Protection:
    • Provides short-circuit protection to protect the circuit from damage.

Applications:

The ADM1485JRZ-REEL is ideal for applications such as low-power RS-485 systems, DTE-DCE interfaces, packet-switched networks, local area networks, data concentration, data multiplexers, and integrated services digital networks (ISDN). Its high-speed, low-power design, and compliance with RS-485 and RS-422 standards make it a versatile choice for a wide range of communication systems.

In summary, the ADM1485JRZ-REEL is a high-performance differential line transceiver that offers high-speed data communication, low power consumption, and compliance with industry standards. Its robust features and versatile packaging make it suitable for a wide range of applications in communication systems.
