(1)Input signal level
All the input signals are at the TTL level. "HIGH" level : 2.0 V at minimum "LOW" level : 0.8 V at maximum
(2)Output signal level
All the output signals are at the TTL level. "HIGH" level : 2.4 V at minimum "LOW" level : 0.4 V at maximum
(3)Input and output conditions
All the input signals are pulled up with a 3.3 kΩ resistor.
