Overview
The TS339ID is a micropower quad CMOS voltage comparator manufactured by STMicroelectronics. It features an extremely low supply current of 9 μA per comparator and operates on a wide single supply range from 2.7 V to 16 V or dual supplies (±1.35 V to ±8 V). The device exhibits an input bias current of 1 pA typical, high input impedance of 10^12 Ω, and a fast response time of 1.5 μs for 5 mV overdrive. It is housed in a 14-SOIC package with an industrial temperature range of -40 °C to +125 °C.
Feature Summary
- Pin-to-pin and functionally compatible with the bipolar LM339 device
- Input common-mode voltage range includes ground potential
- High input impedance characteristic
Applications
- General-purpose signal conditioning
- Voltage monitoring circuits
- Threshold detection systems
Procurement Notes
Verify the specific suffix 'ID' corresponds to the SO14 package and industrial temperature grade (-40°C to +125°C) as defined in the official datasheet ordering table. Confirm that the component status is active production data and check for any environmental compliance markings such as ECOPACK specifications relevant to the manufacturing batch.
Selection Notes
Select this component when a direct replacement for the LM339 is required with significantly lower power consumption. Ensure the application supports open-drain outputs and requires operation within the specified 2.7 V to 16 V supply range. Verify that the 1.5 μs response time meets the system timing requirements for the intended signal frequencies.
Part Context
The TS339 series represents a family of micropower CMOS comparators designed to offer performance similar to the legacy bipolar LM339 while consuming approximately 20 times less current. The TS339ID specifically denotes the industrial grade variant packaged in a 14-pin small outline integrated circuit format, suitable for standard surface-mount assembly processes.
Replacement Considerations
Direct substitutes include the TS339CDT and TS339IPT variants which share functional compatibility but differ in packaging type.
FAQ
What is the maximum differential input voltage allowed?
The absolute maximum rating for differential input voltage is ±18 V.
Does the input common-mode voltage range extend to negative voltages?
No, the input common-mode voltage range starts at ground (0 V).
