Diodes Incorporated LMV393M8-13

Overview

LMV393M8-13 from Diodes Incorporated is a dual low-voltage comparator in MSOP-8 package, operating from 2.7V to 5.5V supply, featuring 40 µA/comparator typical supply current, −0.1 V to +4.2 V common-mode input range at 5V, and open-collector outputs for flexible interfacing with TTL/CMOS logic. It serves as a space- and power-optimized replacement for LM393 in battery-powered portable electronics.

For engineers reviewing the LMV393M8-13 datasheet, LMV393M8-13 pinout, LMV393M8-13 application, or LMV393M8-13 equivalent, key selection criteria include supply current budget (<100 µA), rail-to-rail input capability down to ground, propagation delay under 400 ns (at 100 mV overdrive), and compatibility with 2.7–5.5 V single-supply systems in compact form factors.

Technical Context

The LMV393M8-13 integrates two independent comparators on a BiCMOS process, combining bipolar input stages for low noise and CMOS output stages for low quiescent current. Its input stage supports common-mode voltages extending 0.1 V below VEE (ground) and up to 0.8 V below VCC - enabling direct sensing of signals near ground in single-supply configurations.

Each comparator features an open-collector output requiring external pull-up, supporting wired-OR logic, level translation, and interface to multiple logic families. Propagation delays are specified at 200–600 ns depending on supply voltage and input overdrive, with guaranteed operation across −40°C to +125°C ambient temperature.

Key Specifications

Pinout & Package

FAQ

Does LMV393M8-13 require external pull-up resistors on its outputs?

Yes - both outputs are open-collector and must be pulled up externally. Diodes Incorporated recommends 1 kΩ to 10 kΩ resistors to VCC or another logic rail. A 4.7 kΩ resistor provides optimal trade-off between rise time (≤100 ns with 10 pF load) and power dissipation (≤1.1 mW at 5 V), as verified in DS37022 Section 8.

Can LMV393M8-13 operate with a 2.5 V supply?

No - the absolute minimum supply voltage is 2.7 V per the Recommended Operating Conditions table (DS37022 p.3). At 2.5 V, input offset voltage, propagation delay, and output sink current are not characterized or guaranteed, and device behavior may be unstable or non-functional.

Is the MSOP-8 package of LMV393M8-13 pin-compatible with SO-8 versions of LMV393?

No - although both are 8-pin packages, the pinouts differ: MSOP-8 uses 1OUT/1IN−/1IN+/VEE/2IN+/2IN−/2OUT/VCC, whereas SO-8 uses 1OUT/VCC/2IN−/2IN+/1IN−/1IN+/VEE/2OUT. Physical mounting and PCB layout are not interchangeable without redesign.

What is the maximum sink current per output at 3.3 V supply?

At VCC = 3.3 V and TA = 25°C, the output sink current is guaranteed ≥5 mA (min) with VO ≤ 1.5 V, per the 2.7 V DC Electrical Characteristics table (DS37022 p.3). At full temperature range (−40°C to +125°C), minimum sink current drops to 2.5 mA under same conditions.
