Output Latch Capability

Available in 8-Lead MSOP and SO Packages

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.
