FEATURES
SPT9693
WIDE INPUT V O LTA GE, JFET COMPARATOR
TECHNICAL DATA
MARCH 1, 2001
APPLICATIONS
• Common mode range –3.0 to +8.0 V
• Low input bias current <100 pA
• Propagation delay 1.5 ns (max)
• Low offset ±25 mV
• Low feedthrough and crosstalk
• Differential latch control
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.

TEST LEVEL CODES
All electrical characteristics are subject to the
following conditions:
All parameters having min/max specifications
are guaranteed. The Test Level column indicates the specific device testing actually performed during production and Quality Assurance inspection. Any blank section in the data
column indicates that the specification is not
tested at the specified condition.
LEVEL TEST PROCEDURE
I 100% production tested at the specified temperature.
II 100% production tested at TA = +25 °C, and sample tested at the
specified temperatures.
III QA sample tested only at the specified temperatures.
IV Parameter is guaranteed (but not tested) by design and characteri-
zation data.
V Parameter is a typical value for information purposes only.
VI 100% production tested at TA = +25 °C. Parameter is guaranteed
over specified temperature range.
