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, Vin and

Vout should be constrained to the range VSS ≤ (Vin or Vout) ≤ VDD.

Unused inputs must always be tied to an appropriate logic voltage

level (e.g., either VSS or VDD). Unused outputs must be left open.

†To calculate total supply current at loads other than 50 pF:

IT(CL) = IT(50 pF) + (CL – 50) Vfk

where: IT is in µA (per package), CL in pF, V = (VDD – VSS) in volts, f in kHz is input frequency, and k = 0.001.

‡VH = VT+ – VT– (But maximum variation of VH is specified as less than VT + max – VT – min).
