Description

The HFA-0003/0003L are monolithic, ultra high speed,

voltage comparators. These comparators combine a low

input offset voltage (1.0mV) with a low propagation delay

(2.0ns) to achieve a large dynamic input range. The low off-

set voltage also makes these comparators ideally suited for

high speed, precision analog-to-digital processing applica-

tions. The circuits have differential analog inputs, and pro-

vide complementary, ECL compatible (10K and 100K) logic

outputs. The outputs are capable of supplying the current

required by terminated 50Ω transmission lines. Both outputs

are open emitter structures, requiring external pull-down

resistors. The recommended circuit is 50Ω connected to -

2.0V, but any equivalent ECL termination circuit may be

used.

The HFA-0003L is a latched version of the HFA-0003. The

latch function allows the HFA-0003L to operate in sample-

hold or track-hold modes, when synchronous detection is

required. The Latch Enable (LE) input can be driven by a

standard ECL gate. See the Applications section for more

information on this feature.

The HFA-0003L also has an additional feature, user

programmable hysteresis. By connecting a resistor from the

HYS pin to GND the user can select up to 20mV of input

hysteresis. See the Applications section for more informa-

tion on this feature.

The HFA-0003 is pin compatible with the MAX9690, and

SP9680 while providing improved performance. The HFA-

0003L is pin compatible with the MAX9685, AD96685,

SP9685, HCMP96850, and the VC7695 while providing

improved performance.

... Applications Information HFA-0003L Latch Functionality The Latch Enable (LE) pin of the HFA-0003L controls the function of the on chip latch. When the LE input ECL Logic 1, the latch is open (transparent) and the comparator functions normally. When the LE input switches to a Logic 0, the outputs are latched in unambiguous states dependant on the current input state, providing the set-up and hold times are met ...
