Establishing Static Logic Inputs
The true pin of an input pair is internally biased to ground
through a 75k
resistor. The complement pin of an input
pair is internally biased to V
CC/2 through an internal voltage
divider consisting of two 75k
resistors. Since some logic
functions necessitate an output to be connected to two
inputs, SY55851/A inputs have no internal terminations.
Typically, one resistor between the true and complement
input is all that is required, as per Figure 3. To keep an

input at static logic zero at V
CC ≥ 3.0V, leave both inputs
unconnected or tie the complement input to V
CC. For VCC <
3.0V applications, connect the complement input to V
CC
and leave the true input unconnected. To make an input
static logic one, connect the true input to V
CC, and leave
the complement input unconnected. These are the only safe
ways to cause inputs to be at a static value. In particular,
no input pin should be directly connected to ground. All NC
(no connect) pins should be unconnected.
