TS862IPT

Overview

The TS862IPT is a dual-channel analog comparator manufactured by STMicroelectronics, housed in an 8-TSSOP surface-mount package. It operates on a single supply voltage ranging from 2.7 V to 10 V. The device features rail-to-rail CMOS inputs and push-pull outputs capable of sourcing or sinking up to 5 mA. Key electrical specifications include a maximum input offset voltage of 15 mV at 5 V, a maximum input bias current of 300 pA at 5 V, and a typical common-mode rejection ratio of 70 dB. Quiescent current consumption is 16 µA maximum, with a propagation delay of 2 µs maximum. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Rail-to-rail CMOS input stage allows signal detection near both supply rails.
• Push-pull output structure enables direct interfacing with digital logic without external pull-up resistors.
• Ultra-low power consumption suitable for battery-operated applications.

Applications

• Battery-powered portable electronic systems
• Direct microcontroller interface circuits
• Signal conditioning and threshold detection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the package type and tape-and-reel configuration. Ensure the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement specifications.

Selection Notes

Select this component when a low-power, dual-channel solution with rail-to-rail input capability is required. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design. Verify that the 2.7 V minimum supply voltage aligns with the system's power budget and that the TSSOP-8 package fits the available PCB footprint constraints.

Part Context

This part belongs to the TS86x family of MicroPwr BiCMOS comparators, which includes single (TS861), dual (TS862), and quad (TS864) variants. All members share similar electrical characteristics, including low quiescent current and rail-to-rail operation. The TS862 specifically provides two independent comparators in a compact 8-pin package, offering a balance between channel count and board space efficiency.

Replacement Considerations

Compatible alternatives within the same family include TS861IDT (single channel) and TS864IDT (quad channel). These parts share identical electrical specifications but differ in channel count and package pinout. Verify pin compatibility if substituting directly into an existing layout.

FAQ

Does the TS862IPT require external pull-up resistors?

No, the TS862IPT features a push-pull output stage that can actively drive high and low states, allowing direct connection to digital loads without additional pull-up resistors.

What is the input common-mode voltage range?

The TS862IPT utilizes rail-to-rail CMOS inputs, allowing the common-mode voltage to extend to both the positive and negative supply rails.
