SN75C3238 3V 至 5.5V 多通道 RS-232 线路驱动器/接收器
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/us to 150 V/us.
Flexible control options for power management are featured when the serial-port and driver inputs are inactive
