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.

Product Lifecycle Production
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Evaluation Kits (1)
The MAX13235E evaluation kit (EV kit) provides a proven design to evaluate the MAX13235E, a 3Mbps RS-232 transceiver with low-voltage interface and enhanced electrostatic discharge (ESD) protection. This EV kit demonstrates the MAX13235E in a 20-pin TSSOP package. The MAX13235E is also available in a 20-pin TQFN package with an exposed pad, but that package is not compatible with this EV kit.
The MAX13235E EV kit PCB comes with a MAX13235EEUP+ installed, which is the 3Mbps data-rate version. The MAX13235E EV kit can also be used to evaluate the MAX13234E (250kbps data-rate version). Contact the factory for free samples of the pin-compatible MAX13234EEUP+ to evaluate this device.
