Product details
Overview
TLV3404CDR from Texas Instruments is a quad nanopower open-drain comparator with 470 nA per channel supply current, rail-to-rail input range (–0.1 V to VCC + 5 V), and operation across 2.5 V to 16 V supply. It delivers ultra-low power sensing in battery-critical systems such as portable medical monitors and wireless security sensors.
For engineers reviewing the TLV3404CDR datasheet, TLV3404CDR pinout, TLV3404CDR application, or TLV3404CDR equivalent, key selection criteria include its 4-channel open-drain output architecture, –40°C to +125°C industrial temperature rating, and compatibility with high-impedance pull-up networks for flexible logic-level interfacing.
Technical Context
The TLV3404CDR implements four independent comparators in a single SOIC-14 package, each featuring an open-drain CMOS output stage requiring external pull-up for logic-level translation. Its input stage supports common-mode voltages beyond the positive rail-up to VCC + 5 V-enabling high-side voltage monitoring without level-shifting circuitry.
Designed for nanopower operation, the device maintains stable performance across 2.5 V–16 V supplies and exhibits low input bias current (80 pA typ), low input offset voltage (250 µV typ), and propagation delays ranging from 30 µs (high overdrive) to 300 µs (low overdrive), making it suitable for precision threshold detection where quiescent current dominates system budget.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current per Channel | 470 nA typical - enables multi-year battery life in coin-cell-powered devices |
| Supply Voltage Range | 2.5 V to 16 V - supports single-supply operation from Li-ion to industrial 12 V rails |
| Input Common-Mode Range | –0.1 V to VCC + 5 V - allows direct high-side sensing above VCC without clamping diodes |
| Input Offset Voltage | 250 µV typical - ensures accurate threshold detection at sub-millivolt levels |
| Propagation Delay (tPHL) | 30 µs typical at 50 mV overdrive - balances speed and power for low-frequency event detection |
| Output Type | Open-drain CMOS - enables wired-OR logic, I²C-compatible bus sharing, and flexible voltage translation |
| Operating Temperature | –40°C to +125°C - qualified for automotive cabin, industrial control, and outdoor embedded use |
Pinout & Package
TLV3404CDR is housed in a 14-pin SOIC (D package) with 8.65 mm × 3.91 mm body size and standard JEDEC MS-012AC footprint. The package supports automated assembly and provides thermal resistance RθJA = 83.8°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | 1OUT / 2OUT / 3OUT / 4OUT | Open-drain outputs - require external pull-up resistors; sink current only; support wired-AND logic |
| 2, 6, 9, 13 | 1IN– / 2IN– / 3IN– / 4IN– | Inverting inputs - accept signals up to VCC + 5 V; enable high-side reference comparison |
| 3, 5, 10, 12 | 1IN+ / 2IN+ / 3IN+ / 4IN+ | Noninverting inputs - used for threshold detection against stable references (e.g., REF3312) |
| 4 | VCC | Positive supply pin - powers all four comparators; decoupling capacitor required at pin |
| 11 | GND | Analog ground reference - must connect to low-noise PCB ground plane; shared return for all channels |
Key Features
| Feature | Design Value |
|---|---|
| Nanopower consumption | 470 nA per channel - reduces total system standby current below 2 µA for 4-channel monitoring |
| Rail-to-rail input range | –0.1 V to VCC + 5 V - eliminates need for external level shifters in high-side voltage sense circuits |
| Reverse battery protection | Withstands –18 V on VCC - prevents damage during incorrect battery insertion in field-deployed devices |
| Open-drain output stage | CMOS-compatible sink capability - enables interface with 1.8 V, 3.3 V, or 5 V logic domains via pull-up selection |
| Industrial temperature grade | –40°C to +125°C operation - meets AEC-Q100 Class 0 stress requirements for under-hood and factory-floor use |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3404IDR | Same electrical specs but rated for –40°C to +125°C (I-suffix); TLV3404CDR is C-suffix (0°C to +70°C) | Required for extended temperature deployments (e.g., outdoor gateways, automotive cabins) | Select TLV3404IDR when operating outside 0°C–70°C ambient; otherwise TLV3404CDR suffices for indoor consumer-grade use |
| TLV3604DR | Higher supply current (1.2 µA/ch), faster propagation (1.1 µs), rail-to-rail output - not open-drain | Used where speed > power savings (e.g., motor commutation feedback, fast ADC windowing) | Choose TLV3604DR only if system requires sub-microsecond response; TLV3404CDR remains optimal for <1 µA/channel budgets |
Compared with TLV3404IDR, TLV3404CDR offers identical functionality at lower cost for commercial-temperature applications, while TLV3604DR trades 2.5× higher current for 30× faster switching-making TLV3404CDR the sole choice when nanopower is non-negotiable.

FAQ
What is the maximum supply voltage for TLV3404CDR?
The absolute maximum supply voltage for TLV3404CDR is 17 V, but the recommended operating range is 2.5 V to 16 V. Exceeding 16 V risks violating reliability specifications, even though the device may function temporarily. TI specifies performance parameters only within the 2.5–16 V range, and operation above 16 V voids warranty and accelerates parametric drift over time. Always refer to Section 7.1 Absolute Maximum Ratings in the SLCS135B datasheet for TLV3404CDR.
Does TLV3404CDR support rail-to-rail input operation?
Yes, TLV3404CDR supports rail-to-rail input operation with a common-mode range from –0.1 V to VCC + 5 V. This means inputs can safely exceed the positive supply rail by up to 5 V, enabling direct high-side sensing without external level-shifting components. However, the input voltage must not exceed VCC + 5 V or 20 V (whichever is smaller), per Section 7.1 of the TLV3404CDR datasheet.
What pull-up resistor value is recommended for TLV3404CDR outputs?
Texas Instruments fully specifies TLV3404CDR performance with a 1-MΩ pull-up resistor to VCC. This value balances output rise time, power dissipation, and noise immunity. Lower values (e.g., 10 kΩ) reduce rise time but increase quiescent current; higher values (e.g., 10 MΩ) minimize current but degrade switching speed and noise margin. For TLV3404CDR, 1 MΩ is the validated design point referenced in all electrical characteristics tables.
Is TLV3404CDR pin-compatible with other TLV340x variants?
No, TLV3404CDR is not pin-compatible with TLV3401 or TLV3402 due to differing channel counts and pin assignments. TLV3404CDR uses a 14-pin SOIC package with dedicated pins for four independent inputs and outputs, whereas TLV3402 uses 8-pin packages and TLV3401 uses 5- or 8-pin layouts. Pin mapping is unique to each variant; migration requires PCB redesign. Always verify pin functions in Section 6 of the TLV3404CDR datasheet.
What is the input offset voltage specification for TLV3404CDR?
The input offset voltage for TLV3404CDR is specified as 250 µV typical and 3600 µV maximum at TA = 25°C, with a full-range maximum of 4400 µV across –40°C to +125°C (for I-suffix). The C-suffix TLV3404CDR has a full-range max of 3600 µV. This parameter directly affects threshold accuracy in precision detection circuits and is measured under VIC = VCC/2, RS = 50 Ω, RP = 1 MΩ conditions per Section 7.7 of the TLV3404CDR datasheet.
