Texas Instruments LMV339IPWRG4

Overview

LMV339IPWRG4 from Texas Instruments is a quad low-voltage open-collector comparator operating from 2.7V to 5.5V, delivering 100μA typical supply current, 150mV typical output saturation voltage, and input common-mode range extending to ground. It serves as a space- and power-efficient replacement for LM339 in portable consumer and industrial monitoring circuits.

For engineers reviewing the LMV339IPWRG4 datasheet, LMV339IPWRG4 pinout, LMV339IPWRG4 application, or LMV339IPWRG4 equivalent, key selection criteria include its TSSOP-14 package compatibility, guaranteed operation down to –40°C, and verified 200ns propagation delay at 5V with 100mV overdrive - critical for level-shifting, power sequencing, and threshold-detection designs.

Technical Context

The LMV339IPWRG4 implements four independent PNP-input comparators with open-drain NPN outputs, enabling flexible logic-level translation via external pull-up resistors. Its input stage supports rail-to-rail common-mode operation down to GND (–0.1V min), while output sinking capability reaches 23mA at 2.7V and 84mA at 5V.

Propagation delays are supply- and overdrive-dependent: at VCC = 5V and 100mV overdrive, tPHL = 200ns and tPLH = 300ns; at VCC = 2.7V and same overdrive, tPHL = 350ns and tPLH = 400ns. Input offset voltage remains ≤7mV (typ) across 25°C and ≤9mV (max) over –40°C to 125°C.

FAQ

What is the maximum operating temperature for LMV339IPWRG4?

The LMV339IPWRG4 is specified for continuous operation from –40°C to +125°C ambient temperature. This rating is validated per TI's thermal testing protocol and applies to the full electrical performance envelope, including propagation delay, input offset, and supply current - making LMV339IPWRG4 suitable for under-hood automotive and industrial control environments where thermal stress is critical.

Does LMV339IPWRG4 support rail-to-rail input operation?

LMV339IPWRG4 does not support true rail-to-rail input: its common-mode input range extends from –0.1V to VCC–0.7V at 25°C, meaning the upper limit is ~0.7V below VCC due to PNP input stage V_BE. However, the lower bound includes ground, enabling accurate detection of 0V-referenced signals - a key differentiator from standard rail-to-rail comparators that cannot sense at GND.

Can LMV339IPWRG4 outputs be wire-OR'd together?

Yes - all four outputs of LMV339IPWRG4 are open-drain, allowing direct connection to a shared pull-up resistor. This enables wired-OR logic for consolidated fault signaling (e.g., any comparator asserting low triggers system shutdown). No additional components or isolation are required, and the 23mA sink capability at 2.7V ensures robust drive strength even with multiple outputs active.

What is the recommended bypass capacitor for LMV339IPWRG4?

A 0.1μF X7R ceramic capacitor placed as close as possible between the VCC+ (Pin 11) and GND (Pin 8) pins is mandatory for stable operation. This capacitor suppresses supply noise that could modulate the input common-mode range or induce false triggering. TI's layout guidelines specify no capacitor between GND pin and system ground in single-supply configurations - only the VCC-to-GND bypass is required.

Is LMV339IPWRG4 pin-compatible with LM339DR?

No - LMV339IPWRG4 uses TSSOP-14 packaging with 0.65mm pitch, while LM339DR uses SOIC-14 with 1.27mm pitch. Although both have identical pin functions and numbering (per TI's pinout diagrams), their physical footprints, thermal characteristics, and solder reflow profiles differ significantly. Direct PCB substitution requires layout revision; however, schematic-level functional replacement is straightforward due to matching electrical behavior at 5V.
