directly to TTL/CMOS logic while operating off either ±5V

or single 5V supplies. Tight offset voltage specifications

and high gain allow the LT1016 to be used in precision

applications. Matched complementary outputs further

extend the versatility of this comparator.

A unique output stage provides active drive in both direc-

tions for maximum speed into TTL/CMOS logic or passive

loads, yet does not exhibit the large current spikes found

in conventional output stages. This allows the LT1016 to

remain stable with the outputs in the active region which,

greatly reduces the problem of output “glitching” when

the input signal is slow moving or is low level.

The LT1016 has a LATCH pin which will retain input data

at the outputs, when held high. Quiescent negative power

Linear Technology offers a wide range of comparators

in addition to the LT1016 that address different applica-

tions. See the Related Parts section on the back page of
