Description
TheLT®1016 isanUltraFast10ns comparator that interfaces
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
supply current is only 3mA. This allows the negative supply
pin to be driven from virtually any supply voltage with a
simple resistive divider. Device performance is not affected
by variations in negative supply voltage.
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
the data sheet.
