ordering information This device consists of a dual single-ended line receiver with TTL-compatible strobes and outputs. The reference voltage (switching threshold) is applied externally and can be adjusted from 1.5 V to 3.4 V, making it possible to optimize noise immunity for a given system design. Due to the low input current (less than 100 µA), the device .
