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 guaran-
teed 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 dis-
abled but all receivers are active, allowing unidirection-
al 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 pack-
age, and in a smaller footprint shrink small-outline
package (SSOP).
