Features, Applications

The is a dual line receiver designed to discriminate a worst case logic swing of 2V from 10V common mode noise signal or ground shift. A 1.5V threshold is built into the differential amplifier to offer a TTL compatible threshold voltage and maximum noise immunity. The offset is obtained by use of current sources and matched resistors. The DS9622 allows the choice of output states with the input open, without affecting circuit performance by use A 130 terminating resistor is provided at the input of each line receiver. An enable is also provided for each line receiver. The output is TTL compatible. The output high level can be increased 12V by tying to a positive supply through a resistor. The output circuits allow wired-OR operation.

Note 1: "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices should be operated at these limits. The tables of "Electrical Characteristics" provide conditions for actual device operation. Note 2: Unless otherwise specified Min/Max limits apply across the to +125C temperature range. All typicals are given for VCC = 5V and = 25C. Note 3: All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to ground unless otherwise specified. Note 4: Only one output at a time should be shorted. Note 5: Rating applies to ambient temperatures to +125C. Above 125C ambient, derate linearity at 120C/W.
