MOTOROLA 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 ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎSchottky TTL Load Over the Rated Temperature Range ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ• Resistor Adjustable Trigger Levels ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎMAXIMUM RATINGS* (Voltages Referenced to VSS) ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎSymbol Parameter Value Unit VDD Vin, Vout Iin, Iout DC Supply Voltage Input or Output Voltage (DC or Transient) Input or Output Current (DC or Transient), per Pin – 0.5 to + 18.0 – 0.5 to VDD + 0.5 ± 10 V V mA PD Power Dissipation, per Package† 500 mW Tstg Storage Temperature – 65 to + 150 _C TL Lead Temperature (8–Second Soldering) 260 _C * Maximum Ratings are those values beyond which damage to the device may occur. †Temperature Derating: Plastic “P and D/DW” Packages: – 7.0 mW/_C From 65_C To 125_C Ceramic “L” Packages: – 12 mW/_C From 100_C To 125_C LOGIC DIAGRAM POSITIVE A NEGATIVE A 65 7 COMMON A Ain 9 4 Aout 3–STATE OUTPUT DISABLE 13 11 Aout 14 EXCLUSIVE OR Bin 15 1 COMMON B 23 POSITIVE B2 NEGATIVE B REV 3 1/94 ©MMOotoTrOolaR, IOncL.
