Overview
The LT1016IS8#TRPBF is a single-channel ultra-fast precision comparator manufactured by Analog Devices Inc. It operates on single 5V or ±5V supplies and features complementary outputs compatible with TTL/CMOS logic. Key electrical specifications include a typical propagation delay of 10ns, an input offset voltage of 1mV, and a common mode rejection ratio of 96dB. The device draws 25mA positive supply current and 3mA negative supply current. It is housed in an 8-lead plastic SO package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Ultra-fast response time with tight offset voltage specifications for precision applications
- Complementary output stage provides active drive in both directions without large current spikes
- LATCH pin capability retains input data at the outputs when held high
- Operates stably in the linear region to reduce output glitching with slow-moving signals
Applications
- High Speed A/D Converters
- Zero-Crossing Detectors
- Crystal Oscillators
- Fast Pulse Height/Width Discriminators
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging distinct from tube variants. Confirm the IS8 designation corresponds to the industrial temperature grade (-40°C to +85°C) rather than commercial grades. Ensure compatibility with the required 8-lead SOIC footprint during procurement planning.
Selection Notes
Select this component for designs requiring nanosecond-level response times and direct interface to digital logic families. Consider the low quiescent negative supply current if utilizing resistive dividers for negative rail generation. Evaluate the complementary output configuration against single-ended requirements to maximize versatility.
Part Context
This part belongs to the LT1016 series of ultra-fast comparators designed for high-speed signal processing. It shares architectural similarities with other members of the family but is distinguished by its specific temperature rating and surface-mount packaging format suitable for automated assembly processes.

FAQ
How does the LATCH pin function?
The LATCH pin retains input data at the outputs when held high. To guarantee data retention, the input signal must be valid for at least 5ns before the latch goes high.
What is the common mode input voltage range?
With ±5V supplies, the common mode range is -3.75V to 3.5V. Generally, it is 1.25V above the negative supply and 1.5V below the positive supply.
