1711/LT1712 are UltraFast
TM
4.5ns comparators
featuring rail-to-rail inputs, rail-to-rail complementary out-
puts and an output latch. Optimized for 3V and 5V power
supplies, they operate over a single supply voltage range
from 2.4V to 12V or from
鹵2.4V
to
鹵6V
dual supplies.
The LT1711/LT1712 are designed for ease of use in a
variety of systems. In addition to wide supply voltage
flexibility, rail-to-rail input common mode range extends
100mV beyond both supply rails, and the outputs are
protected against phase reversal for inputs extending
further beyond the rails. Also, the rail-to-rail inputs may be
taken to opposite rails with no significant increase in input
current. The rail-to-rail matched complementary outputs
interface directly to TTL or CMOS logic and can sink 10mA
to within 0.5V of GND or source 10mA to within 0.7V of V
+
.
The LT1711/LT1712 have internal TTL/CMOS compatible
latches for retaining data at the outputs. Each latch holds
data as long as the latch pin is held high. Latch pin
hysteresis provides protection against slow moving or
noisy latch signals. The LT1711 is available in the 8-pin
MSOP package. The LT1712 is available in the 16-pin
narrow SSOP package.
