Product Details

The MAX13234E-MAX13237E are a family of 2 x 2 and 1 x 1 RS-232 and V.28/V.24 transceivers with high speed data rates up to 3Mbps that operate from either a 3.3V or 5V 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 temperature range.
