OUTA: Open-Collector Output of Comparator Section A.

This pin provides drive for up to 40mA of load current. Off-

state voltage may be as high as 18V (36V for LT6700HV)

above GND, regardless of VS used.

GND: Ground. This pin is also the low side return of the

internal 400mV reference.

INA: External Input for Comparator Section A. The volt-

age on this pin can range from –0.3V to 18V (36V for

LT6700HV) with respect to GND regardless of VS used.

The input is noninverting for the LT6700-1/LT6700HV-1

and LT6700-3/LT6700HV-3, and inverting for the LT6700-2/

LT6700HV-2. The other section A comparator input is

internally connected to the 400mV reference.

INB: External Input for Comparator Section B. The volt-

age on this pin can range from –0.3V to 18V (36V for

LT6700HV) with respect to GND regardless of VS used.

The input is noninverting for the LT6700-3/LT6700HV-3,

and inverting for the LT6700-1/LT6700HV-1 and LT6700-2/

LT6700HV-2. The other section B comparator input is

internally connected to the 400mV reference.

VS: Comparator Core Supply Voltage. The parts are char-

acterized for operation with 1.4V ≤ VS ≤ 18V with respect

to GND.

OUTB: Open-Collector Output of Comparator Section B.

This pin provides drive for up to 40mA of load current. Off-

state voltage may be as high as 18V (36V for LT6700HV)

above GND, regardless of VS used.
