TL3116IPW

Comparators Overview

The TL3116IPWR is a single-channel ultra-fast precision analog comparator manufactured by Texas Instruments in a TSSOP-8 surface-mount package. It operates from a single 5-V supply or dual ±5-V supplies, drawing a typical positive supply current of 12.7 mA. The device features complementary push-pull outputs and an input common-mode voltage range that includes the negative rail. Key electrical specifications include a maximum propagation delay of 15 ns, an input offset voltage of 3 mV, and a common-mode rejection ratio of 75 dB. It functions within an operating temperature range of -40°C to +85°C.

Comparators Feature Summary

• Ultra-fast operation with a typical propagation delay of 10 ns
• Low power consumption requiring only 12.7 mA typical supply current
• Complementary outputs capable of latching via the LATCH ENABLE terminal
• Input common-mode voltage extends to the negative rail for ground sensing

Comparators Applications

• Direct interfacing with TTL logic circuits
• Ground sensing applications utilizing negative rail input capability

Comparators Procurement Notes

Verify the active production status and specific ordering suffixes such as .A variants on official Texas Instruments channels. Confirm moisture sensitivity levels and peak reflow temperatures during assembly planning. Ensure compatibility with the required tape and reel packaging dimensions for automated handling equipment.

Comparators Selection Notes

Select this component when high-speed response combined with low power dissipation is critical. The TL3116IPWR serves as a functional replacement for the LT1116 while consuming significantly less power. Consider the TSSOP-8 package constraints and thermal derating factors if operating near the upper temperature limits.
