General Description
The EL2252 dual comparator replaces the traditional input
buffer a attenuator aECL comparator aECL to TTL transla-
tor circuit blocks used in digital equipment The EL2252 pro-
vides a quick 7 ns propagation delay while complying with
g
10V inputs Input accuracy and propagation delay is main-
tained even with input signal Slew Rates as great as 4000 V
ms
The EL2252 can run on supplies as low as b52V and a9V and
comply with ECL and CMOS inputs or use supplies as great as
g
18V for much greater input range
The EL2252 has a
TTL pin which when grounded restricts
the output VOH to a TTL swing to minimize propagation delay
When left open the output VOH increases to a valid CMOS
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 Vb
Elantec’s products and facilities comply with MIL-I-45208A
and other applicable quality specifications For information on
