What are the key features of LM393APE4?
- Dual independent comparator channels in one 8-pin PDIP package for space-efficient designs
- Open-collector output compatible with TTL, CMOS, and wired-AND logic configurations
- Low input bias current of 0.05 µA typical at 25°C minimizing source loading errors
- Wide supply range from 2V to 36V single or ±1V to ±18V dual supply operation
- 2000 µV maximum input offset voltage ensuring accurate threshold detection across temperature
What is LM393APE4 used for?
The LM393APE4 is widely used in window comparator circuits, zero-crossing detectors, and level-shifting applications where two independent voltage comparisons are needed simultaneously. Battery management systems rely on it to detect over-voltage and under-voltage thresholds with open-collector outputs driving LED indicators or relay drivers directly. Industrial sensor signal conditioning, motor speed detection, and analog-to-digital conversion front ends also use this device for reliable analog threshold comparison.

Frequently Asked Questions
How does the open-collector output of LM393APE4 enable wired-AND logic in multi-comparator systems?
Each LM393APE4 output is open-collector, meaning multiple outputs can be wire-tied to a single pull-up resistor without bus contention. If any comparator output pulls low, the shared bus goes low, implementing an AND condition. This saves discrete logic gates in fault detection circuits where 2 or more threshold violations must all be clear for a system-safe signal.
What supply voltage range does LM393APE4 support and how does that affect circuit flexibility?
The LM393APE4 operates on a single supply from 2V to 36V or a dual supply from ±1V to ±18V, accommodating 3.3V, 5V, 12V, and 24V rail systems without redesign. This wide range allows the same part to be used in automotive 12V circuits, industrial 24V PLC inputs, and low-power 3.3V embedded sensor boards, streamlining component inventory management.
For precision threshold detection, how does LM393APE4 input offset voltage affect accuracy?
The LM393APE4 has a maximum input offset voltage of 2000 µV (2 mV), meaning the switching point can deviate by up to 2 mV from the ideal threshold. For a 5V reference divided down to 1V trip point, this 2 mV offset represents only 0.2% error, which is acceptable for most battery monitor and level detector applications without trimming.
How many comparator functions does LM393APE4 integrate and when does that matter for PCB layout?
LM393APE4 integrates 2 independent comparator functions in a single 8-pin PDIP package, halving the component count versus two single-comparator ICs. For through-hole prototype boards and DIP socket applications, this dual integration reduces the number of sockets and decoupling capacitors needed, simplifying layout and cutting assembly time for low-volume industrial and educational designs.
