EL2018 pdf datasheet (Fast, Hi

The EL2018 represents a quantum
leap forward in comparator speed,
accuracy and functionality.
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 the part
maintains 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 glitches. When the output is disabled, the supply
current consumption drops by 50%, but the input stage and
latch remain active.
Elantec facilities comply with MIL-I-45208A and other
applicable quality specifications. For information on Elantec's
