GENERAL DESCRIPTION
The SPT9693 is a high-speed, wide common mode volt-
age, JFET input, dual comparator. It is designed for appli-
cations that measure critical timing parameters in which
wide common mode input voltages of 鈥?.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 com-
patible 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.
