General Description

The DS1631 series of dual peripheral drivers was designed to be a universal set of interface components for CMOS circuits Each circuit has CMOS compatible inputs with thresholds that track as a function of VCC (approximately VCC) The inputs are PNPs providing the high impedance necessary for interfacing with CMOS Outputs have high voltage capability minimum breakdown voltage is 56V at 250 mA The outputs are Darlington connected transistors This allows high current operation (300 mA max) at low internal VCC current levels since base drive for the output transistor is obtained from the load in proportion to the required loading conditions This is essential in order to minimize loading on the CMOS logic supply Typical VCC e 5V power is 28 mW with both outputs ON VCC operating range is 4 5V to 15V The circuit also

Key Features

  • output transistor protection if the VCC supply is lost by forcing the output into the high impe- dance OFF state with the same breakdown levels as when VCC was applied Pin-outs are the same as the respective logic functions found in the following popular series of circuits DS75451 DS75461 This feature allows direct conversion of present systems to the MM74C CMOS family and DS1631 series circuits with great power savings The DS1631 series is also TTL compatible at VCC e 5V Features Y CMOS comp.
