LT1712 - Dual 4.5ns Rail-to-Rail Comparators

The LT1712 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. Latch pin hysteresis provides protection against slow moving or noisy latch signals. The LT1712 is available in the 16-pin narrow SSOP package.
