Functional Replacement to the LT1116
description
The TL31 16 is an ultra-fast comparator designed
to interface directly to TTL logic while operating
from either a single 5-V power supply or dual
±5-V supplies. The input common-mode voltage
extends to the negative rail for ground sensing
applications. It features extremely tight offset
voltage and high gain for precision applications. It
has complementary outputs that can be latched
using the LATCH ENABLE terminal. Figure 1
shows the positive supply current of the
comparator. The TL3116 only requires 12.7 mA
(typical) to achieve a propagation delay of 10 ns.
The TL3116 is a pin-for-pin functional replacement for the LT1116 comparator, offering
high-speed operation but consuming much less
power.
