The MAX13234E–MAX13237E are +3V to +5.5V powered EIA/TIA-232 and V.28/V.24 communications interfaces with high data-rate capabilities (up to 3Mbps), a flexible logic voltage interface, and enhanced electrostatic discharge (ESD) protection. All receiver inputs and transmitter outputs are protected to ±15kV IEC 61000–4-2 Air Gap Discharge, ±8kV IEC 61000-4-2 Contact Discharge, and ±15kV Human Body Model.
The MAX13234E/MAX13235E have two receivers and two transmitters, while the MAX13236E/MAX13237E have a single receiver and transmitter. The transmitters have a low-dropout transmitter output stage, delivering true RS-232 performance from a +3V to +5.5V supply based on a dual charge pump. The charge pump requires only four small 0.1µF capacitors for operation from a +3.3V supply.
All devices achieve a 1µA supply current using Maxim's AutoShutdown Plus™ feature. These devices automatically enter a low-power shutdown mode when the RS-232 cable is disconnected or the devices driving the transmitter and receiver inputs are inactive for more than 30s.
The MAX13234E–MAX13237E are available in space-saving TQFN and TSSOP packages and operate over the -40°C to +85°C extended temperature range.
