DESCRIPTION/ORDERING INFORMATION

The SN65C3238E and SN75C3238E consist 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

devices meet the requirements of TIA/EIA-232-F and provide 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 devices include an always-active noninverting output (ROUT1B),

which allows applications using the ring indicator to transmit data while the device is powered down. These

devices operate at data signaling rates up to 1000 kbit/s.

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.

PRODUCT PREVIEW information concerns products in the

formative or design phase of development. Characteristic data and

other specifications are design goals. Texas Instruments reserves

the right to change or discontinue these products without notice.
