Integral IN1489AD Qudruple line receiver Datasheet

TECHNICAL DATA
IN1489A
Qudruple Line Receivers
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
