Details

Devices in the MAX3483E family (MAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E) are ±15kV ESD-protected, +3.3V, low-power transceivers for RS-485 and RS-422 communications. Each device contains one driver and one receiver. The MAX3483E and MAX3488E feature slew-rate-limited drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission at data rates up to 250kbps. The partially slew-rate-limited MAX3486E transmits up to 2.5Mbps. The MAX3485E, MAX3490E, and MAX3491E transmit at up to 12Mbps.

    FAQs

    What is MAX3491EESD?

    The MAX3491EESD is a high-speed, slew-rate-limited RS-485/RS-422 transceiver designed by Maxim Integrated. It is ideal for applications requiring high-speed data communication, such as industrial automation, telecommunications, and networking.

    How Does MAX3491EESD Work?

    The MAX3491EESD works by providing a robust interface for high-speed data transmission over twisted-pair cables. It includes slew-rate limiting to reduce electromagnetic interference (EMI) and to support longer cable lengths. The transceiver also features fail-safe circuitry to ensure a valid bus state in case of a floating or shorted input condition.

    How Many Pins does MAX3491EESD have and What are the Functions of the Pinout Configuration?

    The MAX3491EESD is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

    • DE, /RE: Driver output and receiver output enables, respectively.
    • A, B: Noninverting and inverting receiver inputs, respectively.
    • GND: Ground pin.
    • B: Noninverting driver input.
    • A: Inverting driver input.
    • VCC: Positive power supply pin.
    • Y, Z: Noninverting and inverting driver outputs, respectively.
    • GND: Ground pin.

    What are the Pros and Cons of MAX3491EESD?

    Pros:

    • High-Speed Data Transmission: Supports high-speed RS-485/RS-422 communication.
    • Slew-Rate Limiting: Helps reduce EMI and enables longer cable lengths.
    • Fail-Safe Circuitry: Ensures a valid bus state in case of input floating or shorting.
    • Robustness: Provides robust interface protection for industrial and harsh environments.
    • Wide Operating Temperature Range: Suitable for applications requiring extended temperature operation.

    Cons:

    • Power Consumption: May have higher power consumption compared to lower-speed transceivers.
    • Package Size: The 14-pin SOIC package may be larger than other form factors in space-constrained designs.
    • Complexity: Requires proper termination and grounding for optimal performance.

    Are There Any Equivalents/Alternatives to MAX3491EESD for Recommendation?

    • The SN65HVD78 from Texas Instruments is an alternative RS-485/RS-422 transceiver with similar features.
    • Similar alternatives to the MAX3491EESD include the LTC2857 from Analog Devices and the ST485B from STMicroelectronics.
