Overview
The AS339GTR-E1 is a quad low-power voltage comparator from Diodes Incorporated, housed in a TSSOP-14 package. It operates on a single supply of 2.0V to 36V or dual supplies of ±1.0V to ±18V. Key electrical parameters include a typical input offset voltage of 2.0mV, supply current drain of 0.9mA at 5V, and an open-collector output capable of sinking up to 16mA. The device functions within a temperature range of -40°C to +85°C.
Feature Summary
- Four independent precision comparators with low power consumption
- Wide single and dual supply voltage operation capability
- Open collector outputs compatible with various logic families
- Input common mode voltage includes ground potential
Applications
- Battery charger circuits
- Cordless telephone systems
- Switching power supply control
- DC-DC module regulation
- PC motherboard monitoring
Procurement Notes
Verify the specific ordering suffix E1 confirms RoHS compliance and lead-free status as defined by Diodes Incorporated standards. Confirm the TSSOP-14 package designation matches the required footprint for the target PCB layout. Ensure the component status aligns with long-term availability requirements, noting that this specific variant may be classified as Not Recommended for New Design.
Selection Notes
Select this component when four independent comparators are required in a compact surface-mount form factor. The wide supply voltage range supports both low-voltage battery applications and higher voltage industrial systems. Verify that the open-collector output configuration suits the downstream logic interface requirements without needing additional pull-up components.
Part Context
This part belongs to the AS339/339A series of low-power, low-offset voltage quad comparators. The 'G' suffix indicates the TSSOP-14 package, while 'E1' denotes RoHS compliance. The series is designed to be compatible with industry standard 339 pinouts, facilitating drop-in replacements in existing designs requiring multiple comparison functions.
Replacement Considerations
AS339GTR-G1 is the confirmed alternative offering Green molding compound properties.
