MC14583B
The MC14583B is a dual Schmitt trigger constructed with complementary
P–channel and N–channel MOS devices on a monolithic silicon substrate.
Each Schmitt trigger is functionally independent except for a common
3–state input and an internally–connected Exclusive OR output for use in
line receiver applications. Trigger levels are adjustable through the positive,
negative, and common t erminals with the u se of external resistors.
Applications include the speed–up of a slow waveform edge in interface
receivers, level detectors, etc.
• Diode Protection on All Inputs
• Supply Voltage Range = 3.0 Vdc to 18 Vdc
• Single Supply Operation
• Capable of Driving Two Low–power TTL Loads or One Low–power
Schottky TTL Load Over the Rated Temperature Range
• Resistor Adjustable Trigger Levels

**The formulas given are for the typical characteristics only at 25_C.
†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 = 0.005.
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
V
out
should be constrained to the range VSS ≤ (Vin or V
out
) ≤ 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.
