MC14584B
Hex Schmitt Trigger
The MC14584B Hex Schmitt Trigger is constructed with MOS
Pchannel and Nchannel 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 Lowpower TTL Loads or One Lowpower
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 PinforPin
Replacement for CD40106B and MM74Cl4

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
highimpedance circuit. For proper operation, V

and V
out
should be constrained
to the range V

Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
either V

or V

). Unused outputs must be left open.
