Overview
The LM239DTBR2G is a quad comparator from onsemi, housed in a TSSOP-14 package. It operates on a single supply of 3.0 V to 36 V or split supplies of ±1.5 V to ±18 V. Key electrical characteristics include a typical input bias current of 25 nA and an input offset voltage of ±5.0 mV at +25 °C. The device features open-collector outputs capable of sinking up to 16 mA. Large signal response time is typically 1.3 µs. Operating temperature range extends from -25 °C to +85 °C.
Feature Summary
- Supports single supply operation from 3.0 V to 36 V and split supply operation from ±1.5 V to ±18 V.
- Features low input bias current of 25 nA (typical) and low input offset voltage.
- Outputs are TTL and CMOS compatible with open-collector configuration.
- Includes ESD clamps on inputs to increase reliability without affecting device operation.
Applications
- Level detection
- Low-level sensing
- Memory applications
Procurement Notes
Verify the specific suffix DTBR indicates the TSSOP-14 package and tape & reel shipping format. Confirm RoHS compliance and lead-free status as stated in the ordering information. Ensure the operating temperature range matches the LM239 specification (-25 °C to +85 °C) rather than the commercial LM339 variant. Check for any automotive-specific requirements if NCV prefix parts are needed instead.
Selection Notes
Select this component when four independent comparators are required in a compact surface-mount package. The LM239 variant offers extended low-temperature performance compared to the LM339. Consider the open-collector output requirement for interfacing with different logic families. Verify that the input common mode voltage range extending to ground meets circuit design needs.
Part Context
This part belongs to the LM239/LM339 family of single supply quad comparators manufactured by onsemi. It shares functional similarities with the LM339 but differs in specified operating temperature ranges. The DTBR suffix denotes the TSSOP-14 package type and reel packaging. It is distinct from the SOIC-14 version (DR2G suffix).
Replacement Considerations
LM239DR2G is a pin-compatible alternative in the SOIC-14 package. LM339DTBR2G is functionally similar but has a different operating temperature range (0 °C to +70 °C). STMicroelectronics LM239APT is a comparable quad comparator in TSSOP-14.
FAQ
What is the input common mode voltage range?
The input common mode voltage range extends from 0 V to VCC minus 1.5 V.
Can differential input voltages exceed the supply voltage?
Yes, differential input voltages may be larger than supply voltages without damaging the inputs, provided they do not go more negative than -300 mV.
