description/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 is suited ideally for party-line (data-bus) systems.
The SN74LS2323 has a common reference-voltage pin and a common strobe.
