ICL232 ICL232是美国HARRIS公司生产的一种双RS232收发器。它满足EIA RS232C的技术要求。它的特点是:单5V供电;内部有两个电荷泵电压变换电路,用以产生所需的±V电压;两个驱动器的输入为+5V,输出为±9V,300Ω断电电源阻抗,输出电流受限制,TTL/CMOS兼容;最大的压摆率为30V/μs;两个接收器的输入电压范圃为-30V～30V,输入阻抗3～7kΩ,为改善噪声抑制有0.5V的迟滞。 该器件可应用于任何需要RS-232通信接口的设备,如计算机、计算机外设、便携式仪器、调制解调器及数据采集器等。
ICL232 ICL232 is a kind of double RS232 transceiver produced by HARRIS Company of USA. It meets the technical requirements of EIA RS232C. Its features are: single 5V supply; internal charge pump voltage conversion circuit to produce the required ± V voltage; two drivers input + 5V, the output is ± 9V, 300Ω power supply impedance, the output Current limited, TTL / CMOS compatible; maximum slew rate of 30V / μs; two receiver input voltage range is -30V ~ 30V, the input impedance of 3 ~ 7kΩ, to improve the noise suppression with 0.5V hysteresis. The device can be applied to any device that requires RS-232 communication interface, such as computers, computer peripherals, portable instruments, modems and data acquisition.
