KK1489A

www.DataSheet4U.com TECHNICAL DATA KK1489A Qudruple Line Receivers The KK1489A is a monolithic quadruple line receivers designed to satisfy the requirements of the standard interface between data terminal equipment and data communication equipments as defined by EIA standard RS-232C. A separate response control terminal is provided for each receiver. A resistor or a resistor and bias voltage can be connected between this terminal and ground to shift the input threshold voltage levels. An external capacitor can be connected from this terminal to ground to provide input noise filtering. Input Resistance ... 3 kΩ to 7kΩ Input Signal Range ... ±30 V Operates from Single 5 V Supply Built-IN Input Hysteresis (Double Thresholds) Response Control Provides: Input Tresold Shifting Input Noise Filtering Satisfies Requirements of EIA RS-232C ORDERING INFORMATION KK1489AN Plastic KK1489AD SOIC TA = -10° to 70° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs A L H Output Y H L PIN 14 =VCC PIN 7 = GND 1 www.DataSheet4U.com KK1489A MAXIMUM RATINGS* Symbol VCC VIN IO Tstg * Parameter Supply Voltage Input Voltage Output Current Storage Temperature Range Value 6 ±25 10 -65 to +150 Unit V V mA °C Maximum Ratings are those values beyond which damage to the device may occur.
