SEMICONDUCTOR TECHNICAL DATA
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.
Supply Voltage Range = 3.0 Vdc to 18 Vdc
Capable of Driving Two Low–power TTL Loads or One Low–power
Schottky TTL Load over the Rated Temperature Range
Double Diode Protection on All Inputs
Can Be Used to Replace MC14069UB
For Greater Hysteresis, Use MC14106B which is Pin–for–Pin
Replacement for CD40106B and MM74Cl4

EQIVALENT CIRCUIT SCHEMATIC
(1/6 OF CIRCUIT SHOWN)
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
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.
