Product details
Overview
TLV9034PWR from Texas Instruments is a quad-channel precision comparator with push-pull output, 300μV input offset voltage, 100ns propagation delay, and rail-to-rail fault-tolerant inputs supporting 1.65V–5.5V supply. It operates across –40°C to +125°C and drives capacitive loads or MOSFET gates in motor control feedback loops.
For engineers reviewing the TLV9034PWR datasheet, TLV9034PWR pinout, TLV9034PWR application, or TLV9034PWR equivalent, key selection criteria include quad-channel push-pull drive capability, sub-20μA per-channel quiescent current, 5pA input bias current, and 6V fault-tolerant input rating for industrial voltage monitoring.
Technical Context
The TLV9034PWR implements a precision comparator architecture with internal biasing optimized for low-voltage operation down to 1.65V and high noise immunity via rail-to-rail fault-tolerant inputs rated to 6V beyond V–. Its push-pull output stage sources/sinks ≥4mA at 5V, enabling direct LED or gate-drive interfacing without external pull-ups.
Designed for harsh industrial environments, it features ±0.5µV/°C input offset drift, 75–95dB PSRR, and 60–70dB CMRR over full temperature range. The device maintains stable propagation delay (100ns HL, 115ns LH) with 15pF load and exhibits <3ns rise/fall times under 5V conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad push-pull comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Open-drain output, higher 100μA/channel IQ, ±2mV offset, no fault-tolerant inputs | Requires external pull-ups; unsuitable for 1.65V operation or 6V transient environments | Choose LM339DR only if cost is primary constraint and system uses 5V supply with robust ESD protection |
| TLV9034IDR | Same electrical specs but in SOIC-14 package (3.91mm × 8.65mm); no thermal pad | Larger footprint and lower thermal performance; preferred for through-hole prototyping | Choose TLV9034IDR when board assembly uses wave soldering or requires legacy SOIC compatibility |
Compared with LM339DR and TLV9034IDR, TLV9034PWR delivers 5× lower quiescent current, 6× better input offset, and integrated fault tolerance-making it optimal for space-constrained, low-power, high-reliability industrial monitoring where thermal management and voltage margin matter.

FAQ
What is the maximum input voltage the TLV9034PWR can tolerate without damage?
The TLV9034PWR inputs are fault-tolerant up to 6V relative to V–, meaning they withstand –0.3V to 6V regardless of supply voltage. This allows direct connection to 5V logic or 4–20mA loop signals without external clamping. Absolute maximum ratings confirm this limit applies across the full –40°C to +125°C temperature range. Exceeding 6V may cause permanent damage.
Does the TLV9034PWR support rail-to-rail input common-mode range?
Yes, the TLV9034PWR supports a rail-to-rail input common-mode range from (V–) – 0.2V to (V+) + 0.2V across its full operating temperature range. This enables accurate comparison of signals near supply rails-critical for battery voltage monitoring where V+ may drop to 1.65V. The specification is verified at both 1.8V and 5V supply conditions.
Can the TLV9034PWR drive a MOSFET gate directly?
Yes, the TLV9034PWR's push-pull output can source and sink ≥4mA at 5V, sufficient to charge/discharge typical small-signal MOSFET gates (e.g., 1nF gate capacitance) within microseconds. Rise/fall times are ≤3ns under 5V/15pF conditions. For larger power MOSFETs, a dedicated gate driver remains recommended-but TLV9034PWR eliminates intermediate buffering in low-side switching applications.
What is the typical quiescent current per channel of the TLV9034PWR at 1.8V supply?
The TLV9034PWR draws 16μA per channel at 1.8V supply and 25°C, rising to 35μA maximum across –40°C to +125°C. This ultra-low IQ enables always-on voltage supervision in battery-powered edge devices. Figure 5-1 in the datasheet confirms stable current draw across 1.5V–5.5V, with minimal variation vs. temperature or input voltage.
Is the TLV9034PWR pin-compatible with other TLV90xx quad comparators?
No-TLV9034PWR (TSSOP-14) is not pin-compatible with TLV9024PWR (open-drain quad) due to differing output stage requirements, though both share identical pin numbering for inputs, supplies, and GND. TLV9034PWR is functionally and pinout-compatible with TLV9034IDR (SOIC-14), differing only in package dimensions and thermal pad presence.
