IN1489A中文资料IKSEMICON数据手册PDF规格书

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
