EL2252C  
Dual 50 MHz Comparator/Pin Receiver  
Features  
# Fast responseÐ7 ns  
# Inputs tolerate large overdrives  
with no speed nor bias current  
penalties  
General Description  
The EL2252 dual comparator replaces the traditional input  
a
a a  
attenuator ECL comparator ECL to TTL transla-  
tor circuit blocks used in digital equipment. The EL2252 pro-  
buffer  
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.  
# Propagation delay is relatively  
constant with variations of input  
Slew Rate, overdrive,

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  
temperature, and supply voltage  
g
18V for much greater input range.  
# Output provides proper CMOS or  
TTL logic levels  
The EL2252 has a /TTL pin which, when grounded, restricts  
the output V to a TTL swing to minimize propagation delay.

# Large voltage gainÐ8000 V/V

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-
