General Description

The EL2252 dual comparator replaces the traditional input buffer a attenuator aECL comparator +ECL to TTL translator circuit blocks used in digital equipment. The EL2252 provides a quick 7 ns propagation delay while complying with ±10V inputs. Input accuracy and propagation delay is maintained even with input signal Slew Rates as great as 4000 V/μs. The EL2252 can run on supplies as low as -5.2V and +9V and comply with ECL and CMOS inputs, or use supplies as great as ±18V for much greater input range.
