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 ISO11898 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.

These devices operate at a high-speed CAN data rate, allowing up to 2Mbps on small networks. Maximum speed on large networks may be limited by the number of nodes in a network, the type of cabling used, stub length, and other factors. These transceivers include a dominant timeout to prevent bus lockup caused by controller error or by a fault on the TXD input. When TXD remains in the dominant state (low) for longer than TDOM, the driver is switched to the recessive state, releasing the bus. The MAX33053E features an S pin where it enables and disables the transmitter for applications where you need the transceiver to receive only. The MAX33054E features a STBY pin for 3 modes of operation; standby mode for low-current consumption, normal high-speed mode, or a slow slew rate mode when an external 26.1kΩ is connected between ground and STBY pin.

The MAX33053E and MAX33054E are available in a standard 8-pin SOIC package and operate over the -40°C to +125°C temperature range.
