SEMICONDUCTOR TECHNICAL DATA
Dual Schmitt Trigger
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 terminals with the use 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
