Overview
The TS393CD is a dual micropower CMOS voltage comparator manufactured by Taiwan Semiconductor Corporation. It operates within a supply voltage range of 2.7 V to 16 V and draws a typical operating current of 20 uA per device. The component features a response time of 2.5 us, an input offset voltage of 5 mV, and an input bias current of 600 pA. Each channel provides an output current capability of 20 mA. Designed for surface-mount applications, it is housed in an SOIC-8 package and functions across a temperature range from 0 C to +70 C.
Feature Summary
- Micropower CMOS architecture designed for low energy consumption
- Dual differential voltage comparison functionality
- CMOS logic-compatible output stage
Applications
- Battery-powered monitoring systems
- Over-voltage protection circuits
- Threshold detection applications
Procurement Notes
Verify the manufacturer designation as Taiwan Semiconductor Corporation against official datasheets. Confirm the SOIC-8 package type and commercial temperature range specifications. Ensure the part number matches the specific dual comparator configuration required for the design.
Selection Notes
Select this component when low quiescent current is critical for battery life. The CMOS output interface suits digital logic integration. Verify that the 2.7 V minimum supply voltage aligns with the system power rails and that the 20 mA sink capability meets load requirements.
Part Context
This device belongs to the TS393 series of analog comparators. It serves as a low-power alternative to bipolar comparators, offering reduced standby current while maintaining standard voltage comparison performance in a compact surface-mount form factor.
Replacement Considerations
Cross-reference with LM393 or TL393 variants for pin-compatible alternatives. Verify that substitute parts support the required 2.7 V minimum supply voltage and CMOS output characteristics.
