DESCRIPTIO

The LT

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 LT1016, LT1116 and LT1671,

this comparator has complementary outputs designed to

interface directly to TTL or CMOS logic. The LT1394 may

operate from either a single 5V supply or dual 5V supplies.

Low offset voltage specifications and high gain allow the

LT1394 to be used in precision applications.

The LT1394 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-conduc-

tion current. Unlike other fast comparators, the LT1394

remains stable even for slow transitions through the active

region, which eliminates the need to specify a minimum input

slew rate.

The LT1394 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.
