资 源 简 介

The EL2252 dual comparator replacesthe tradiTIonal input buffer + attenuator+ECL comparator +ECL to TTLtranslator circuit blocks used in digital equipment. TheEL2252 provides a quick 7ns propagaTIon delay whilecomplying with ±10V inputs. Input accuracy and propagaTIondelay is maintained even with input signal Slew Rates asgreat as 4000V/μs. The EL2252 can run on supplies as lowas -5.2V and +9V and comply with ECL and CMOS inputs,or use supplies as great as ±18V for much greater inputrange.The EL2252 has a /TTL pin which, when grounded, restrictsthe output VOH to a TTL swing to minimize propagaTIondelay. When left open, the output VOH increases to a validCMOS level.
