MAX211
- RS-232 bus-pin ESD protection exceeds ±15kv using human-body model (HBM)
- Meets or exceeds the requirements of TIA/EIA-232-F and ITU v.28 standards
- Operates at 5V V CC supply
- Four drivers and five receivers
- Operates up to 120kbit/s
- Low supply current in shutdown mode: 5µA typical
- External capacitors: 4 × 0.1µF
- Latch-up performance exceeds 100mA per JESD 78, class II
The MAX211 device consists of four line drivers, five line receivers, and a dual charge-pump circuit with ±15kV ESD protection pin to pin (serial-port connection pins, including GND). The device meets the requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector. The charge pump and four small external capacitors allow operation from a single 5V supply. The devices operate at data signaling rates up to 120kbit/s and a maximum of 30V/µs driver output slew rate.
The MAX211 has both shutdown (SHDN) and enable control (EN). In shutdown mode, the charge pumps are turned off, V+ is pulled down to VCC, V− is pulled to GND, and the transmitter outputs are disabled. This reduces supply current typically to 1µA. EN is used to put the receiver outputs into the high-impedance state to allow wired-OR connection of two RS-232 ports. It has no effect on the RS-232 drivers or the charge pumps.
