Overview
The TS864IYDT is a rail-to-rail micropower BiCMOS quad comparator manufactured by STMicroelectronics. It operates within a supply voltage range of 2.7 V to 10 V and supports an operating temperature range from -40 °C to +85 °C. The device features four differential channels with push-pull outputs, consuming 6 μA per comparator at 2.7 V. Key electrical parameters include a response time of 2 μs, a propagation delay of 1.5 μs, and an input offset voltage of 15 mV. Each channel provides an output current capability of 5 mA, while the maximum power dissipation is rated at 830 mW.
Feature Summary
- Rail-to-rail CMOS inputs enable full signal swing compatibility across the supply range.
- Push-pull output stage allows direct connection to microcontrollers without external pull-up resistors.
- Ultra-low current consumption optimizes performance for battery-powered systems.
- Integrated ESD protection and latch-up immunity ensure robust operation in harsh environments.
Applications
- Battery-powered portable electronic devices
- Microcontroller interface circuits
- Signal conditioning applications
Procurement Notes
Verify the specific suffix 'IYDT' against official STMicroelectronics documentation to confirm the industrial temperature grade, SOIC-14 package, and tape-and-reel packaging configuration. Ensure that the ordering information matches the exact part number required for your design specifications, as suffixes define critical physical and environmental attributes.
Selection Notes
Select this component when designing low-power systems requiring multiple comparators with rail-to-rail input capabilities. The push-pull output simplifies circuit design by eliminating the need for external pull-up resistors. Consider the 2.7 V minimum supply voltage and 6 μA quiescent current per channel when evaluating power budgets for battery-operated applications.
Part Context
The TS864IYDT 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 excellent speed-to-power ratios and availability in compact packages such as SOT23-5, SO-8, SO-14, TSSOP-8, and TSSOP-14. The TS864IYDT specifically utilizes the SOIC-14 package format.
Replacement Considerations
Compatible alternatives within the same family include TS861IDT, TS862IDT, and TS864IDT, which share similar electrical characteristics but differ in channel count or package type. Verify pinout compatibility and thermal performance when substituting parts with different package footprints.
