MAX33053EASA+

The MAX33053E and MAX33054E are +3.3V CAN (Control Area Network) transceivers with integrated protection for industrial applications. These devices have extended ±65V fault protection for equipment where overvoltage protection is required. It also incorporates high ±25kV ESD HBM and an input common mode range (CMR) of ±25V, exceeding the ISO 11898 specification of -2V to +7V. This makes these parts well-suited for applications that are in electrically noisy environments where the ground planes are shifting relative to each other. This family features a variety of options to address common CAN application requirements; logic-level supply input VL for interfacing with 1.62V to 3.6V logic, low-current standby mode, silent-mode to disable the transmitter, and a slow slew rate to minimize EMI.
