EL2019C Fast High Voltage Comparator with Master Slave Flip-Flop Features Comparator cannot oscillate Fast response 5 ns data to clock setup 20 ns clock to output Wide input differential voltage range 24V on g15V supplies Wide input common mode voltage range g12V Precision input stage VOS e 1 5 mV Low input bias current 100 nA Low input offset current 30 nA g4 5V to g18V supplies 3 State TTL compatible output No supply current glitch during switching 103 dB voltage gain (Low input uncertainty 30 mV) 50% power reduction in shut- down mode Input and flip-flop remain active in shutdown mode Applications Analog to digital converters ATE pin receiver Zero crossing detector Window detector ‘‘Go no-go’’ detector Ordering Information Part No Temp Range Pkg Outline EL2019CN b40 C to a85 C P-DIP MDP0006 General Description The EL2019 offers a new feature previously unavailable in a comparator before a master slave edge triggered flip-flop The comparator output will only change output state after a posi- tive going clock edge is applied Thus the output can’t feed back to the input and cause oscillation Manufactured with Elantec’s proprietary Complementary Bipolar process this device uses fast PNP and NPN transistors in the signal path A unique circuit design gives the inputs the ability to handle large com- mon mode and differential mode signals yet retain high speed and excellent accuracy Careful design of the front end insures speed and accuracy when operating with a mix of small and large signals The three-state output stage is designed to be TTL compatible for any power supply combination yet it draws a constant current and does not generate current glitches When the output is disabled the supply current consumption drops by 50% but the input stage and master slave flip-flop remain active Elantec facilities comply with MIL-I-45208A and other applica- ble quality specifications For information on Elantec’s process- ing see QRA1 Elantec’s Processing-Monolithic Products Connection Diagrams 8-Pin Plastic DIP Top View 2019 – 2 Note All information contained in this data sheet has been carefully checked and is believed to be accurate as of the date of publication however this data sheet cannot be a ‘‘controlled document’’ Current revisions if any to these specifications are maintained at the factory and are available upon your request We recommend checking the revision level before finalization of your design documentation 1989 Elantec Inc Free Datasheet http://www.datasheetlist.com/ 1 page EL2019C Fast High Voltage Comparator with Master Slave Flip-Flop Typical AC Performance Curves Contd Input Bias Current vs Differential Input Voltage Input Bias Current vs Temperature Input Bias Current vs Common Mode Voltage VO VI Transfer Characteristics Supply Current vs Supply Voltage Supply Current vs Temperature 2019 – 4 5 Free Datasheet http://www.datasheetlist.com/ 5 Page EL2019C Fast High Voltage Comparator with Master Slave Flip-Flop Burn-In Circuit Pin numbers are for DIP packages All packages use the same schematic Equivalent Schematic 2019 – 12 11 2019 – 13 Free Datasheet http://www.datasheetlist.com/ 11 Page
