MC14584B
Hex Schmitt Trigger
The MC14584B Hex Schmitt Trigger is constructed with MOS
P–channel and N–channel enhancement mode devices in a single
monolithic structure. These devices find primary use where low power
dissipation and/or high noise immunity is desired. The MC14584B
may be used in place of the MC14069UB hex inverter for enhanced
noise immunity to “square up” slowly changing waveforms.

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 V
SS
(V
in
or V

)
V

.
Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
either V
SS
or V
DD
). Unused outputs must be left open.
