Overview
The AS393P-E1 is a dual precision voltage comparator manufactured by Diodes Incorporated in an 8-pin PDIP package. It operates from a single supply of 2V to 36V or split supplies of ±1.0V to ±18V. The device features a typical input offset voltage of 1.0mV, low supply current drain of 0.6mA, and open-collector outputs. It supports ground-sensed inputs and differential input voltages equal to the power supply voltage.
Feature Summary
- Dual independent precision voltage comparators with high gain
- Wide operating supply voltage range for single or split configurations
- Low power consumption with supply current independent of voltage magnitude
- Open-collector output structure compatible with various logic families
Applications
- Battery chargers
- Cordless telephones
- Switching power supplies
- DC-DC modules
- PC motherboards
Procurement Notes
Verify component authenticity through authorized Diodes Incorporated channels. Confirm RoHS compliance status and check for End-of-Life (EOL) designation prior to procurement. Ensure packaging specifications match design requirements as PDIP-8 variants are marked EOL without replacements.
Selection Notes
Select this part for applications requiring wide supply voltage operation and low offset voltage. Verify that the open-collector output configuration meets system interface needs. Consider thermal resistance characteristics for PCB layout planning. Evaluate alternative packages if surface-mount technology is required.
Part Context
This component belongs to the AS393/393A series of low-power, low-offset voltage dual comparators. It is designed to be compatible with industry standard 393 devices. The PDIP-8 package variant is specifically designated as End-of-Life (EOL) with no direct replacement provided by the manufacturer.
Replacement Considerations
The AS393P-E1 is listed as End-of-Life (EOL) with no official replacement part numbers available. Designers must evaluate alternative components or redesign circuits to accommodate discontinued inventory constraints.
