Function
No Connect. Leave pin unconnected.
One of two complementary outputs for channel
A. QA will be at logic HIGH if the analog
voltage at the NONINVERTING INPUT is
greater than the analog voltage at the
INVERTING INPUT (provided the
comparator is in the “compare” mode). See
LATCH ENABLE channel A for additional
information
One of two complementary outputs for channel
A. /QA will be at logic LOW if the analog
voltage at the NONINVERTING INPUT is
greater than the analog voltage at the
INVERTING INPUT (provided the
comparator is in the “compare” mode). See
LATCH ENABLE channel A for additional
information.
Analog ground.
One of two complementary inputs for channel
A Latch Enable. In the “compare” mode
(logic HIGH), the output will track changes at
the input of the comparator. In the “l(fā)atch”
mode (logic LOW), the output will reflect the
input state just prior to the comparator being
placed in the “l(fā)atch” mode. /LEA must be
driven in conjunction with LEA.
No Connect. Leave pin unconnected.
One of two complementary inputs for channel
A Latch Enable. In the “compare” mode
(logic LOW), the output will track changes at
the input of the comparator. In the “l(fā)atch”
mode (logic HIGH), the output will reflect the
input state just prior to the comparator being
placed in the “l(fā)atch” mode. LEA must be
driven in conjunction with /LEA.
Negative Supply Terminal
Inverting analog input of the differential input
stage for channel A. The INVERTING A
INPUT must be driven in conjunction with the
NONINVERTING A INPUT.
Noninverting analog input of the differential
input stage for channel A. The
NONINVERTING A INPUT must be driven
in conjunction with the INVERTING A
INPUT.
No Connect. Leave pin unconnected.
Noninverting analog input of the differential
input stage for channel B. The
NONINVERTING B INPUT must be driven in
conjunction with the INVERTING B INPUT.
Inverting analog input of the differential input
stage for channel B. The INVERTING B
INPUT must be driven in conjunction with the
NONINVERTING B INPUT.
