EL2019C

EL2019C 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 g 15V supplies  Wide input common mode voltage range g 12V  Precision input stage VOS e 1 5 mV  Low input bias current 100 nA  Low input offset current 30 nA  g 4 5V to g 18V 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 shutdown mode  Input and flip-flop remain active in shutdown mode 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 positive 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 common 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 glit...
