LT1715 Independent Input/Output Supplies FEATURES

1 LT171511715fa TYPICAL APPLICATION DESCRIPTION4ns, 150 MHz Dual Comparator with Independent Input/Output SuppliesThe LT 1715 is an UltraFast dual comparator optimized for low voltage operation. Separate Supplies allow Independent analog input ranges and output logic levels with no loss of performance. The input voltage range extends from 100mV below VEE to below VCC. Internal hysteresis makes the LT1715 easy to use even with slow moving input signals. The rail-to-rail outputs directly interface toTTL and CMOS. The symmetric output drive results in similar rise and fall times that can be harnessed for analog applications or for easy translation to other single supply logic LT1715 is available in the 10-pin MSOP package.

2 The pinout of the LT1715 minimizes parasitic effects by placing the most sensitive inputs away from the outputs, shielded by the power a dual/quad single supply comparator with simi-lar propagation delay, see the LT1720/LT1721. For a single comparator with similar propagation delay, see the Dual Differential Line ReceiverL, LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
