The NTE75189 is a monolithic low−power Schottky quadruple line receiver in a 14−lead DIP-type package designed to satisfy the requirements of the standard interface between data terminal equipment and data communication equipment as defined by EIA Standard RS−232−C. A separate response control pin is provided for each receiver. A resistor or a resistor and bias voltage source can be connected between this pin and GND to shift the input threshold levels. An external capacitor can be connected between this pin and GND to provide input noise filtering.
Response control provides: Input threshold shifting Input noise filtering
Absolute Maximum Ratings: (TA= 0 to +70°C unless otherwise specified)
Supply voltage VCC: 10V
Input voltage: ±30V
Output current: 20mA
Continuous total dissipation (TA ≤ +25°C) PD: 1025mW
Operating ambient temperature range TA: 0 to +70°C
Storage temperature range Tstg: -65° to + 150°C
Lead temperature (during soldering 1/16" (1.6mm) from case, 60 sec Max) TL: +300°C
All voltage values are with respect to the network GND pin
