SN75LBC173 Features

* high input impedance, input hysteresis for increased noise immunity, and input sensitivity of ± 200 mV over a common-mode input voltage range of 12 V to

* 7 V. Fail-safe design ensures that if the inputs are open circuited, the output is always high. Both devices are designed using the Texas
