Overview
The LM193 MD8 is a dual precision voltage comparator manufactured by Texas Instruments, supplied as a bare die in the DIESALE (Y) package. It operates from a single power supply ranging from 2.0 VDC to 36 VDC or split supplies of ±1.0 VDC to ±18 VDC. The device features an input common-mode voltage range that includes ground and outputs compatible with TTL, DTL, ECL, MOS, and CMOS logic systems. Key electrical characteristics include a maximum input offset voltage of 5.0 mV, typical supply current of 1.0 mA at 5 V, and response times of 5.0 µs for low overdrive and 0.8 µs for high overdrive.
Feature Summary
- Dual independent precision comparators designed for wide single-supply operation
- Input common-mode voltage range includes ground potential
- Output voltage levels compatible with standard digital logic families
- Low power supply current drain independent of supply voltage magnitude
Applications
- Limit comparators
- Simple analog-to-digital converters
- Pulse and squarewave time delay generators
- Wide range voltage-controlled oscillators
- MOS clock timers
Procurement Notes
Verify the specific ordering suffix against the Package Option Addendum to confirm the DIESALE (Y) configuration and JEDEC tray carrier specifications. Ensure compatibility with the intended substrate assembly process for bare die mounting. Confirm RoHS compliance status and moisture sensitivity level ratings prior to procurement.
Selection Notes
Select this component when radiation tolerance or military qualification is not required but high precision and low power are needed. The LM193 series offers reduced offset voltage drift over temperature compared to standard comparators. Verify that the application circuit provides adequate protection against negative input voltages exceeding -0.3 VDC.
Part Context
The LM193 series consists of two independent low voltage comparators designed specifically for single-supply operation. This family includes variants such as the LM193A, LM293, LM393, and LM2903. The LM193 MD8 represents the bare die version of this architecture, offering the same functional performance in a form factor suitable for hybrid microelectronics or custom packaging solutions.

FAQ
Can the differential input voltage exceed the positive supply voltage?
Yes, positive excursions of the input voltage may exceed the power supply level without damaging the device, provided the other input remains within the common-mode range.
Is bypassing required across the power supply line?
It is usually unnecessary to use a bypass capacitor across the power supply line for this device.
How should unused comparators be handled?
All input pins of any unused comparators should be tied to the negative supply.
