OUTA (Pin 1):
Open-Collector Output of Comparator Sec-
tion A. This pin provides drive for up to 40mA of load
current. Off-state voltage may be as high as 18V above
GND (Pin 2), regardless of V
S
used.
GND (Pin 2):
Ground. This pin is also the low side return
of the internal 400mV reference.
INA (Pin 3):
External Input for Comparator Section A. The
voltage on this pin can range from –0.3V to 18V with
respect to GND (Pin 2) regardless of V
S
used. The input is
noninverting for the LT6700-1 and LT6700-3, and invert-
ing for the LT6700-2. The other section A comparator
input is internally connected to the 400mV reference.
INB (Pin 4):
External Input for Comparator Section B. The
voltage on this pin can range from –0.3V to 18V with
respect to GND (Pin 2) regardless of V
S
used. The input is
noninverting for the LT6700-3, and inverting for the
LT6700-1 and LT6700-2. The other section B comparator
input is internally connected to the 400mV reference.

OUTB (Pin 6):
Open-Collector Output of Comparator Sec-
tion B. This pin provides drive for up to 40mA of load
current. Off-state voltage may be as high as 18V above
GND (Pin 2), regardless of V
S
used.

ELECTRICAL CHARACTERISTICS
Note 1:
Absolute Maximum Ratings are those beyond which the life of the
device may be impaired.
Note 2:
A heat sink may be required to keep the junction temperature
below the absolute maximum rating when the output is shorted
indefinitely.
Note 3:
The inputs are protected by ESD diodes to the ground. If the input
voltage exceeds –0.3V below ground, the input current should be limited
to less than 10mA.
Note 4:
The LT6700CS6-1/-2/-3 and LT6700IS6-1/-2/-3 are guaranteed
functional over the operating temperature range of –40
°
C to 85
°
C. The
LT6700HS6-1/-2/-3 are guaranteed functional over the operating
temperature range of –40
°
C to 125
°
C.
Note 5:
The LT6700CS6-1/-2/-3 are guaranteed to meet the specified
performance from 0
°
C to 70
°
C. The LT6700CS6-1/-2/-3 are designed,
characterized and expected to meet specified performance from –40
°
C to
85
°
C but are not tested or QA sampled at these temperatures. The
LT6700IS6-1/-2/-3 are guaranteed to meet specified performance from
–40
°
C to 85
°
C. The LT6700HS6-1/-2/-3 are guaranteed to meet specified
performance from –40
°
C to 125
°
C.
