description/ordering information
The ’C3238 devices consist of five line drivers, three line receivers, and a dual charge-pump circuit with 15-kV
ESD protection pin to pin (serial-port connection pins, including GND). The charge pump and four small external
capacitors allow operation from a single 3-V to 5.5-V supply. In addition, these 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 1 Mbit/s and at an increased
slew-rate range of 24 V/µs to 150 V/µs.
