The MAX3187CAX is a full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 4.5V to 5.5V supply and supports data rates up to 230kbps. The device features a receiver hysteresis of 650mV for noise immunity and functions within an industrial temperature range of 0°C to 70°C.
Verify the specific suffix 'CAX' against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels and interface requirements before integration.
Select this component for applications requiring reliable full-duplex RS-232 transmission at moderate speeds. Consider the 650mV hysteresis for noisy environments and verify power supply constraints align with the 4.5V minimum requirement.
This part belongs to the MAX3187 family of RS-232 transceivers. It provides standard serial communication functionality suitable for legacy and industrial interfaces, differing from other Maxim sensors or converters in its specific protocol support.
Consult official substitution lists for compatible RS-232 transceivers. Verify pinout and electrical specifications match when replacing with similar models from Analog Devices or third-party manufacturers.
