Overview

Data Rate Up to 3Mbps for Faster Throughput
Saves Board Space
- Integrated Low-Voltage Logic for Easy Interface with ASICs and Microcontrollers
- Integrated ±15kV HBM ESD Protection
- Integrated Charge-Pump Circuitry Requiring Only Four External 0.1µF Capacitors for 3.3V Operation
+3V to +5.5V Supply Voltage
AutoShutdown Plus Achieves 1µA Shutdown Current Reduces Power Consumption
Available in 20-pin TSSOP, TQFN-EP, and 16-pin TQFN
-40°C to +85°C Operating Temperature

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 Details

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.
