APPLICATIONS INFORMATION Power Supply Confi gurations The LT1715 has separate supply pins for the input and output stages that allow fl exible operation, accommodating separate voltage ranges for the analog input and the output logic. Of course, a single 3V/5V ...
Page 10
LT1715 APPLICATIONS INFORMATION When both input signals are above the positive common mode limit, the input stage will get debiased and the output polarity will be random. However, the internal hysteresis will hold the output to a valid logic level. ...
Page 11
APPLICATIONS INFORMATION The ground trace from Pin 6 runs under the device up to the bypass capacitor, shielding the inputs from the outputs. Note the use of a common via for the LT1715 and the bypass capacitors, which minimizes interference ...

LT1715 APPLICATIONS INFORMATION Unused Comparators If a comparator is unused, its output should be left fl oa- tingto minimize load current. The unused inputs can be tied off to the rails and power consumption can be further minimized if the ...

LT1715 APPLICATIONS INFORMATION Of course, if the V of the LT1715 is the same as the EE ECL negative supply, the GND pin can be tied well and +V grounded. Then the output stage has the same ...

APPLICATIONS INFORMATION ECL, and particularly PECL, is valuable technology for high speed system design, but it must be used with care. With less than a volt of swing, the noise margins need to be evaluated carefully. Note that there is ...

LT1715 APPLICATIONS INFORMATION The bias conditions and signal swings in the output stage are designed to turn their respective output transistors off faster than on. This helps minimize the surge of current from +V to ground that occurs at transitions, ...
Page 17
APPLICATIONS INFORMATION The gain and hysteresis stage of the LT1715 is simple, short and high speed to help prevent parasitic oscillations while adding minimum dispersion. This internal “self-latch” can be usefully exploited in many applications because it occurs early in ...
