Applications
The TS393ID dual comparator is ideal for battery-powered monitoring circuits, threshold detectors, and window comparator designs where the 0.0006 µA bias current minimizes quiescent power drain. Its open-drain output structure makes it suitable for level-shifting interfaces and wired-OR bus configurations in industrial and consumer electronics. The SOIC-8 package fits standard 8-pin footprints, simplifying integration into existing board designs.

Frequently Asked Questions
How low is the input bias current of TS393ID and why does it matter for battery-powered designs?
The TS393ID has a maximum input bias current of just 0.0006 µA at 25°C, which is extremely low and ensures negligible loading on high-impedance sensor sources, significantly extending battery life in portable threshold-detection and voltage monitoring circuits.
What supply voltage range does TS393ID support and how does its open-drain output simplify system design?
The TS393ID operates with a negative supply voltage limit of -18V, supporting a wide range of supply configurations. Its open-drain output allows direct interface to different logic voltage levels and enables wired-OR connections between multiple comparator outputs without additional level-shifting circuitry.
For a window comparator circuit monitoring a 3.3V signal, how does TS393ID's dual configuration help?
The TS393ID integrates 2 independent comparators in a single SOIC-8 package, so one unit provides both the upper and lower threshold comparisons needed for a window comparator, saving board space and reducing component count compared to using 2 separate single comparator ICs.
When is TS393ID a suitable alternative to LM393 in micropower designs?
The TS393ID is preferable to standard LM393 variants when bias current must be minimized below 1 µA, since TS393ID's 0.0006 µA specification is orders of magnitude lower, making it the better choice for high-impedance inputs and energy-harvesting systems where every microamp of quiescent current matters.
