Description

The MAX3243 device consists of three line drivers, five line receivers which is ideal for DE-9 DTE interface. ±15kV ESD (HBM) protection pin to pin (serial- port connection pins, including GND). Flexible power features saves power automatically. Special outputs ROUT2B and INVALID are always enabled to allow checking for ring indicator and valid RS232 input.
