Product details
Overview
74LV14AT14-13 from Diodes Incorporated is a hex Schmitt-trigger inverter IC in TSSOP-14 package, operating from 2.0V to 5.5V supply, delivering 12mA output drive at 4.5V, with 5.5V-tolerant inputs and IOFF partial-power-down protection-used for signal conditioning and voltage translation in mixed-voltage digital interfaces.
For engineers reviewing the 74LV14AT14-13 datasheet, 74LV14AT14-13 pinout, 74LV14AT14-13 application, or 74LV14AT14-13 equivalent, key selection criteria include input hysteresis (0.5–2.0V), propagation delay (5.1–19.7ns), IOFF leakage (<5μA), rail-to-rail input tolerance, and TSSOP-14 thermal and layout constraints.
Technical Context
This device implements six independent inverters, each with Schmitt-trigger inputs providing noise-immune switching via defined VT+ (1.31–3.5V) and VT− (0.75–3.05V) thresholds across VCC = 2.5V/3.3V/5.0V. Hysteresis ranges from 0.25V to 2.0V, enabling robust edge detection in noisy environments.
The IOFF circuit disables outputs during power-down, preventing backflow current when VCC = 0V while inputs remain at up to 5.5V-critical for hot-swap and partial-power-down systems. Input clamp current is rated ±20mA, and latch-up immunity exceeds 100mA per JESD78 Class I.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0V to 5.5V - supports direct interface with 2.5V, 3.3V, and 5V logic domains |
| Input Voltage Tolerance | Up to 5.5V - enables use as level shifter without external components |
| Output Drive Current | ±12mA at VCC = 4.5V - sufficient to drive multiple CMOS loads or small capacitive traces |
| Propagation Delay | 5.1ns (min) to 10ns (max) at 5.0V, CL = 15pF - ensures timing predictability in high-speed control paths |
| Hysteresis Width | 0.5V to 2.0V (VCC-dependent) - rejects noise spikes up to specified amplitude on slow or noisy signals |
| IOFF Leakage | <5μA at VI/VO = 0–5.5V - prevents bus contention during system sleep or reset states |
| ESD Robustness | 2kV HBM, 1kV CDM, 200V MM - meets industrial-grade handling requirements without additional protection |
Pinout & Package
TSSOP-14 package: 4.9mm × 4.4mm body, 0.65mm pitch, 1.2mm height, exposed pad optional, JEDEC MO-153 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (1A–6A) | Schmitt-trigger input per inverter stage; accepts 0–5.5V regardless of VCC |
| 2, 4, 6, 8, 10, 12 | Output (1Y–6Y) | Push-pull CMOS output; sinks or sources up to 12mA at VCC = 4.5V |
| 7 | GND | Ground reference for all logic and power domains; must be low-impedance return path |
| 14 | VCC | Primary supply rail; powers internal logic and output drivers; IOFF active when VCC = 0V |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs per gate | Enables reliable waveform shaping of slow-rise or noisy signals without external RC networks |
| IOFF partial-power-down support | Prevents destructive back-current flow when VCC is off but bus lines remain live |
| 5.5V-tolerant I/O | Allows direct connection to 5V buses while operating from 2.5V or 3.3V supplies |
| Low dynamic power consumption | ICC ≤ 20μA at VCC = 5.5V - reduces quiescent load in battery-backed or always-on subsystems |
| Industry-standard TSSOP-14 footprint | Ensures drop-in compatibility with existing PCB layouts and reflow profiles |
Applications
| Industrial Sensor Interface | USB Peripheral Power Control |
|---|---|
Use Scenario: Conditioning analog sensor outputs (e.g., thermistor, potentiometer) before ADC sampling in PLC modules. IC Role / Device Role / Timing Role: Signal conditioner converting slow, noisy analog-derived logic edges into clean square waves for microcontroller GPIO capture. Use Value: Hysteresis (≥0.5V at 5V) eliminates chatter from EMI-coupled sensor wiring without software debouncing. | Use Scenario: Enabling/disabling USB VBUS power to downstream peripherals based on host controller commands. IC Role / Device Role / Timing Role: Level-shifting and inverting enable signal between 3.3V host MCU and 5V power switch FET gate driver. Use Value: 5.5V-tolerant inputs accept 5V USB status signals; IOFF prevents backfeed when host sleeps. |
| Embedded System Reset Sequencing | Legacy Bus Signal Isolation |
Use Scenario: Debouncing and synchronizing mechanical reset button inputs in automotive infotainment head units. IC Role / Device Role / Timing Role: First-stage hardware debouncer feeding cleaned signal to reset supervisor IC or MCU reset pin. Use Value: VT+ / VT− thresholds ensure stable transition despite contact bounce duration >10ms and ESD transients. | Use Scenario: Isolating legacy parallel bus (e.g., ISA, LPC) signals between powered-down and active subsystems. IC Role / Device Role / Timing Role: Bidirectional isolation buffer with IOFF-enabled tri-state behavior during power domain transitions. Use Value: IOFF leakage <5μA prevents unintended logic state corruption on shared bus lines during partial shutdown. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LV14APW | Same function, SOIC-14 package; higher ICC (30μA typical); no IOFF specification | Lacks IOFF - unsuitable for partial-power-down systems requiring back-current prevention | Select when board space allows SOIC and power-down isolation is not required |
| 74LVC14ABQ | 14-pin DHVQFN; IOFF supported; 1.65–5.5V range; lower hysteresis (0.2–1.2V) | Narrower hysteresis reduces noise margin in high-EMI environments | Prefer for ultra-compact designs where thermal performance and fine-pitch assembly are prioritized |
Compared with SN74LV14APW and 74LVC14ABQ, the 74LV14AT14-13 uniquely balances TSSOP-14 compactness, full IOFF protection, and wide hysteresis (up to 2.0V), making it optimal for mixed-voltage industrial control boards needing both noise resilience and safe power sequencing.

FAQ
Can 74LV14AT14-13 operate reliably at 2.0V supply?
Yes. The device is fully characterized down to 2.0V: propagation delay remains within 22ns (max), output drive sustains ≥2mA, and Schmitt thresholds (VT+ = 1.75V, VT− = 0.75V at 2.5V) scale predictably. Input hysteresis stays functional, ensuring noise rejection even at minimum VCC.
Does 74LV14AT14-13 require external pull-up resistors on inputs?
No. Unused inputs must be tied to VCC or GND per datasheet Note 5 to prevent floating states and increased ICC. Internal structure does not include weak pull-ups; external biasing is mandatory only for unconnected pins-not for normal operation of driven inputs.
What is the maximum capacitive load this device can drive?
The datasheet specifies timing with CL = 15pF and 50pF loads. While not explicitly rated beyond 50pF, output drive capability (±12mA) supports moderate trace capacitance. For >50pF, verify setup/hold margins and consider adding series termination to limit ringing and ensure clean edges.
Is thermal pad connection required for TSSOP-14 package?
No. The TSSOP-14 variant (T14) used in 74LV14AT14-13 has no exposed thermal pad per Diodes' AP02002 outline. Standard soldering per IPC-7095 is sufficient; no thermal via or pad grounding is needed or recommended for this specific package variant.
