com APPLICATIONS • • • • • • • • Automated test equipment High-speed instrumentation Window comparators High-speed timing Line receivers High-speed triggers Threshold detection Peak detection GENERAL DESCRIPTION The SPT9693 is a high-speed, wide common mode voltage, JFET input, dual comparator.
It is designed for applications that measure critical timing parameters in which wide common mode input voltages of –3.
0 to +8.
0 V are required.
Propagation delays are constant for overdrives greater than 50 mV.
JFET inputs reduce the input bias currents to the nanoamp level, eliminating the need for input drivers and buffers in most applications.
The device has differential analog inputs and complementary logic outputs compatible with ECL systems.
Each comparator has a complementary latch enable control that can be driven by standard ECL logic.
The SPT9693 is available in 20-contact LCC and 20-lead PLCC packages over the commercial temperature range.
It is also available in die form.
