DS1633 Datasheet | National Semiconductor

Description The DS1631 series of dual peripheral drivers was designed to be a universal set of interface ponents for CMOS circuits Each circuit has CMOS patible 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 m A The outputs are Darlington connected transistors This allows high current operation (300 m A 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 m W with both outputs ON VCC operating range is 4 5V to 15V The circuit also 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 patible at VCC e 5V Features Y CMOS patible inputs Y High impedance inputs PNP’s Y High output voltage breakdown 56V min Y High output current capability 300 m A max Y Same pin-outs and logic functions as DS75451 and DS75461 series circuits Y Low VCC power dissipation (28 m W both outputs ‘‘ON’’ at 5V) Connection Diagrams (Dual-In-Line and Metal Can Packages) TL F 5816- 1 Top View Order Number DS1631J-8 or DS3631N TL F 5816 - 2 TL F 5816 - 3 Top View Top View Order Number DS1632J-8 Order Number DS1633J-8 or DS3632N or DS3633N See NS Package Number J08A or N08E TL F 5816 - 4 Top View Order Number DS1634J-8 or DS3634N TL F 5816- 5 Top View (Pin 4 is electrically connected to the...
