MAX3238E datasheet

Description :

DESCRIPTION/ORDERING INFORMATION
The MAX3238E consists of five line drivers, three line receivers, and a dual charge-pump circuit with ±15-kV ESD (HBM) protection on the driver output (DOUT) and receiver input (RIN) terminals. The device meets the requirements of TIA/EIA-232-F and provides the electrical interface between notebook and subnotebook computer applications. The charge pump and four small external capacitors allow operation from a single 3-V to
5.5-V supply. In addition, the device includes an always-active noninverting output (ROUT1B), which allows applications using the ring indicator to transmit data while the device is powered down. This device operates at data signaling rates up to 250 kbit/s and a maximum of 30-V/µs driver output slew rate.
