The LT
1671 is a low power 60ns comparator with comple-
mentary outputs and latch. The input common mode
range extends from 1.5V below the positive supply down
to the negative supply rail. Like the LT1394, LT1016 and
LT1116, this comparator has complementary outputs
designed to interface directly to TTL or CMOS logic. The
LT1671 may operate from either a single 5V supply or dual
±5V supplies. Low offset voltage specifications and high
gain allow the LT1671 to be used in precision applications.
The LT1671 is designed for improved speed and stability
for a wide range of operating conditions. The output stage
provides active drive in both directions for maximum
speed into TTL, CMOS or passive loads with minimal
cross-conduction current. Unlike other fast comparators,
the LT1671 remains stable even for slow transitions
through the active region, which eliminates the need to
specify a minimum input slew rate.
The LT1671 has an internal, TTL/CMOS compatible latch
for retaining data at the outputs. The latch holds data as
long as the LATCH pin is held high. Device parameters
such as gain, offset and negative power supply current are
not significantly affected by variations in negative supply
voltage.
