The MC34152/MC33152 are dual noninverTIng high speed driversspecifically designed for applicaTIons that require low current digitalsignals to drive large capaciTIve loads with high slew rates. Thesedevices feature low input current making them CMOS/LSTTL logiccompaTIble, input hysteresis for fast output switching that isindependent of input transition time, and two high current totem poleoutputs ideally suited for driving power MOSFETs. Also included isan undervoltage lockout with hysteresis to prevent system erraticoperation at low supply voltages.Typical applications include switching power supplies, dc−to−dcconverters, capacitor charge pump voltage doublers/inverters, andmotor controllers.This device is available in dual−in−line and surface mount packages.Features• Pb−Free Packages are Available• Two Independent Channels with 1.5 A Totem Pole Outputs• Output Rise and Fall Times of 15 ns with 1000 pF Load• CMOS/LSTTL Compatible Inputs with Hysteresis• Undervoltage Lockout with Hysteresis• Low Standby Current• Efficient High Frequency Operation• Enhanced System Performance with Common Switching RegulatorControl ICs• NCV Prefix for Automotive and Other Applications Requiring Siteand Control Changes
