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-
