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/ µ s driver output slew rate.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
