EL2252C

Dual 50 MHz Comparator Pin Receiver

General Description

The EL2252 dual comparator replaces the traditional input

buffer

tor circuit blocks used in digital equipment The EL2252 pro-

vides a quick 7 ns propagation delay while complying with

tained even with input signal Slew Rates as great as 4000 V

The EL2252 can run on supplies as low as

comply with ECL and CMOS inputs or use supplies as great as

The EL2252 has a TTL pin which when grounded restricts

the output V

When left open the output V

level

The comparators are well behaved and have little tendency to

oscillate over a variety of input and output source and load

impedances They do not oscillate even when the inputs are

held in the linear range of the device To improve output stabili-

ty in the presence of input noise an internal 60 mV of hystere-

sis is available by connecting the HYS pin to V

Elantec’s products and facilities comply with MIL-I-45208A

and other applicable quality specifications For information on
