Overview
The TS864IDT is a rail-to-rail micropower BiCMOS quad comparator from STMicroelectronics, characterized for operation between 2.7 V and 10 V over -40 °C to +85 °C. It features an ultra-low current consumption of 6 μA per comparator at 2.7 V and a response time of 500 ns at 2.7 V for a 100 mV overdrive. The device includes ESD protection rated at 2 kV and latch-up immunity (Class A). It utilizes push-pull outputs for direct microcontroller interfacing without pull-up resistors and is available in the SO-14 package.
Feature Summary
- Rail-to-rail CMOS inputs with push-pull output structure
- Ultra-low power consumption suitable for battery-powered systems
- Integrated ESD protection and Class A latch-up immunity
Applications
- Battery-powered electronic systems
- Direct microcontroller signal interfacing
- General-purpose voltage comparison circuits
Procurement Notes
Verify the specific suffix 'IDT' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and quantity. Ensure the operating temperature range and supply voltage specifications align with your system requirements before finalizing procurement decisions.
Selection Notes
Select this component when low power consumption and rail-to-rail input/output capabilities are required. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design. Verify that the 500 ns propagation delay meets the timing constraints of your application.
Part Context
This part belongs to the TS86x family, which includes single, dual, and quad comparator variants. The family shares common characteristics such as BiCMOS technology, rail-to-rail operation, and micropower performance. Other members may differ in channel count or package type while maintaining similar electrical profiles.
Replacement Considerations
Consult the manufacturer's official documentation for verified substitute part numbers within the TS86x family or equivalent series. Do not assume functional compatibility with other generic quad comparators without verifying pinout and electrical parameter alignment.
