LT1016IS8

Overview

The LT1016IS8#PBF is a single-channel ultra-fast precision comparator manufactured by Analog Devices Inc. It operates on a single 5V supply or ±5V dual supplies within an 8-lead plastic SOIC package. The device features complementary outputs compatible with TTL and CMOS logic, offering a typical propagation delay of 10ns and a maximum input offset voltage of 3.5mV. It includes a latch enable pin for data retention and maintains stability in the linear region without output glitching.

Feature Summary

• Ultra-fast response time with tight offset voltage specifications for precision applications
• Complementary outputs directly interface with TTL/CMOS logic families
• Active drive output stage prevents current spikes and reduces output glitching
• Latch capability retains input data at outputs when the control pin is held high

Applications

• High-speed A/D converters
• Crystal oscillators
• Zero-crossing detectors
• Fast pulse height/width discriminators

Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and RoHS compliance. Confirm the IS8 designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure the 8-lead Plastic SO package matches the PCB footprint requirements. Check for availability through designated sales channels if tape and reel quantities are required instead of tube packaging.

Selection Notes

Select this component when low propagation delay and high gain are critical for signal integrity. The device is suitable for applications requiring operation from a single 5V supply or dual ±5V rails. Consider the latch feature if data retention during input transitions is necessary. Verify that the input source impedance remains low to prevent instability caused by stray capacitance.

Part Context

The LT1016 series represents a family of ultra-fast comparators designed for high-speed digital interfacing. The IS8 variant specifically denotes the industrial temperature grade housed in a surface-mount SOIC package. This part bridges the gap between general-purpose comparators and specialized high-speed logic gates, offering precise analog threshold detection with digital output compatibility.

Replacement Considerations

LT1016CS8#PBF: Commercial temperature version (0°C to 70°C).

FAQ

How does the LATCH pin function?

Holding the LATCH pin high retains the input data at the outputs. 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 extends 1.25V above the negative supply and 1.5V below the positive supply.
