TS864AIDT

Overview

The TS864AIDT is a quad comparator from STMicroelectronics, housed in a 14-SOIC 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 input bias current of 300pA at 5V, a typical CMRR of 70dB, and a maximum propagation delay of 2µs. It supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Rail-to-rail CMOS inputs enable full signal swing compatibility across the supply range.
• Push-pull output stage allows direct interfacing with microcontrollers without additional components.
• Ultra-low power consumption design optimizes efficiency for battery-powered applications.

Applications

• Battery-powered systems requiring low quiescent current
• Direct microcontroller interface circuits
• Signal conditioning in portable electronic devices

Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors. Confirm RoHS3 compliance and check for obsolete status indicators, as availability may vary. Ensure the 14-SOIC package matches your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits that require multiple comparators with minimal power draw. The push-pull output simplifies logic level translation, while the wide supply voltage range accommodates various battery chemistries. Consider thermal dissipation limits within the SO-14 package for high-density layouts.

Part Context

This part belongs to the TS86x family, which includes single, dual, and quad variants. The family is characterized by its BiCMOS technology, offering a balance between speed and power efficiency. It is designed for general-purpose comparison tasks in consumer and industrial electronics where space and energy constraints are critical.

Replacement Considerations

Check for equivalent quad comparators with similar supply ranges and output types. Verify pinout compatibility if substituting directly into existing designs. Ensure replacement parts meet the same temperature and electrical specifications.
