Complete 230kbps, 2.7V to 5.25V Serial Interface for Notebook Computers

The MAX562 is designed specifically for notebook and palmtop computers that need to transfer data quickly. It runs at data rates up to 230kbps, and has a guaranteed 4V/µs slew rate. This device meets the new EIA/TIA-562 standard that guarantees compatibility with RS-232 interfaces.

The MAX562 has low-power shutdown and keep-awake modes. In keep-awake mode, the transmitters are disabled but all receivers are active, allowing unidirectional communication. In shutdown mode, the entire chip is disabled and all outputs are in a high-impedance state.

The MAX562 is available in a standard 28-pin SO package, and in a smaller footprint shrink small-outline package (SSOP).
