TS864IPT

Overview

The TS864IPT is a quad analog comparator manufactured by STMicroelectronics, housed in a 14-TSSOP surface-mount package. It operates on a single or dual supply voltage ranging from 2.7V to 10V. The device features rail-to-rail CMOS inputs and push-pull outputs, eliminating the need for external pull-up resistors. Key electrical specifications include a maximum propagation delay of 2µs, a typical CMRR of 70dB, and a maximum input offset voltage of 15mV at 5V. Quiescent current consumption is limited to 16µA maximum, with an input bias current of 300pA at 5V. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Rail-to-rail CMOS input stage allows signal detection across the full supply voltage range.
• Push-pull output structure enables direct interfacing with microcontrollers without additional components.
• Ultra-low power consumption design suitable for battery-powered applications.
• Integrated ESD protection and latch-up immunity for enhanced reliability.

Applications

• Battery-powered portable systems requiring low quiescent current
• Direct interface circuits with microcontrollers and digital logic
• General-purpose signal conditioning and threshold detection

Procurement Notes

Verify the specific ordering suffix to ensure the correct tape and reel configuration matches your assembly requirements. Confirm that the 14-TSSOP package dimensions align with your PCB footprint constraints. Check the latest datasheet for any updates regarding moisture sensitivity levels or recommended soldering profiles before finalizing procurement.

Selection Notes

Select this component when a quad comparator with rail-to-rail input capability is required in a compact surface-mount package. It is appropriate for designs needing push-pull outputs to simplify circuit topology. Consider the 2.7V minimum supply voltage and 16µA current consumption limits against system power budgets. Ensure the 2µs propagation delay meets the timing requirements of the application.

Part Context

The TS864IPT belongs to the TS86x family of rail-to-rail micropower BiCMOS comparators, which includes single (TS861), dual (TS862), and quad (TS864) variants. This family is characterized by an excellent speed-to-power ratio, making it ideal for energy-efficient designs. The TS864 specifically integrates four independent comparators within a single 14-pin TSSOP package to save board space.

Replacement Considerations

Compatible alternatives within the same family include the TS861, TS862, and TS864 in various packages such as SOT23-5, SO-8, and SO-14. Verify pinout compatibility and package dimensions when substituting with other members of the TS86x series or similar quad comparators from other manufacturers.
