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.
Analog Devices 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.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Input offset voltage is defined as the average of the two voltages
measured by forcing first one output, then the other to 1.4V. Input offset
current is defined in the same way.
Note 3: Input bias current (IB) is defined as the average of the two input
currents.
Note 4: tPD and ∆tPD cannot be measured in automatic handling equipment
with low values of overdrive. The LT1016 is sample tested with a 1V step
and 500mV overdrive. Correlation tests have shown that tPD and ∆tPD
limits shown can be guaranteed with this test if additional DC tests are
performed to guarantee that all internal bias conditions are correct. For low
overdrive conditions VOS is added to overdrive. Differential propogation
delay is defined as: ∆tPD = tPDLH – tPDHL
Note 5: Electrical specifications apply only up to 5.4V.
Note 6: Input voltage range is guaranteed in part by CMRR testing and
in part by design and characterization. See text for discussion of input
voltage range for supplies other than ±5V or 5V.
Note 7: This parameter is guaranteed to meet specified performance
through design and characterization. It has not been tested.
