TECHNICAL DATA
IW4093B
Quad 2-Input NAND Schmitt Triggers
High-Voltage Silicon-Gate CMOS
The IW4093B consists of four Schmitt-trigger circuits. Each circuit
functions as a two-input NAND gate with Schmitt-trigger action on
both inputs. The gate switches at different points for positive- and
negative- going signals. The difference between the positive voltage
(V
P
) and the negative voltage (V
N
) is defined as hysteresis voltage (V
H
)
(see Fig.1).

This device contains protection circuitry to guard against damage due to high static voltages or electric
fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated
voltages to this high-impedance circuit. For proper operation, V
IN
and V
OUT
should be constrained to the range
GND≤(V
IN
or V
OUT
)≤V
CC
.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V
CC
).
Unused outputs must be left open.
