RS232C LINE DRIVER/RECEIVER GENERAL DESCRIPTION The NJU54028 is a RS232C line driver/receiver composed of 3drivers convert the input of TTL level signals into RS232C lever signals and limit the slew rate below 30V/US. The receivers accept the input levels both of RS-232C standard minimum requirement level(+-3V)and TTL level. Furthermore,the hysteresis circuit and noise filter incorporated on each receiver ensures noise-freeoperation. FEATURES Based on the RS232C Standard 3 Drivers and 3 Receivers Low Operating Current Driver Output Voltage---_+25V Receiver lnput Voltage---_+27V Output lmpedance at power-off(Driver) www.m448中国最大的欧亿·体育（中国）有限公司库下载
