IN1489A

Qudruple Line Receivers TECHNICAL DATA IN1489A The IN1489A 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 IN1489AN Plastic IN1489AD SOIC TA = -10° to 70° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT PIN 14 =VCC PIN 7 = GND ...
