Product details
Overview
74LVC00AT14-13 from Diodes Incorporated is a quad 2-input NAND gate IC operating across 1.65V–5.5V supply, with 5.5V-tolerant inputs, IOFF-enabled partial power-down protection, and 3.3V/5V voltage translation capability-used in logic-level shifting and signal isolation in embedded control subsystems.
For engineers reviewing the 74LVC00AT14-13 datasheet, 74LVC00AT14-13 pinout, 74LVC00AT14-13 application, or 74LVC00AT14-13 equivalent, key selection criteria include VCC range compatibility, IOFF leakage (<20 µA), propagation delay (≤5.5 ns at 3.3V), output drive strength (24 mA sink), and TSSOP-14 thermal resistance (159°C/W).
Technical Context
This device implements four independent positive-logic NAND gates (Y = A·B) with rail-to-rail input tolerance up to 5.5V and guaranteed operation down to 1.65V. Its IOFF circuit actively disables outputs during power-down, preventing backflow current into powered rails.
It supports mixed-voltage interfacing between 1.8V, 2.5V, 3.3V, and 5V domains without external level shifters. Switching performance is characterized across temperature (–40°C to +125°C) and voltage (1.65V–5.5V), with propagation delay tightly specified (e.g., 3.5–4.1 ns typical at 3.3V, 25°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - enables single-supply operation across low-voltage microcontrollers and legacy 5V peripherals. |
| Input Voltage Tolerance | Up to 5.5V - allows direct connection to 5V signals while powered from 3.3V or lower, eliminating external clamping. |
| IOFF Leakage Current | ≤20 µA at –40°C to +125°C - ensures safe bus isolation during partial power-down in hot-swap or sleep-mode systems. |
| Output Drive (Sink) | 24 mA at VCC = 3.3V - sufficient to directly drive LED indicators, small MOSFET gates, or TTL-compatible loads. |
| Propagation Delay | 3.5 ns (typ) at 3.3V, 25°C - supports >100 MHz toggle rates in non-critical timing paths like address decoding or enable gating. |
| ESD Protection | HBM: 2 kV, CDM: >1 kV - exceeds JEDEC standards for robustness in board assembly and field handling. |
| Operating Temperature | –40°C to +125°C - qualified for industrial and extended-temperature embedded applications. |
Pinout & Package
TSSOP-14 package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed pad optional, JEDEC MO-153 compliant. Thermal resistance θJA = 159°C/W on standard FR-4 PCB with minimum recommended copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | Input A (Gate 1–4) | Primary NAND input; 5.5V-tolerant, compatible with 1.65V–5.5V logic families. |
| 2, 5, 10, 13 | Input B (Gate 1–4) | Secondary NAND input; identical electrical specs to Input A pins. |
| 3, 6, 8, 11 | Output Y (Gate 1–4) | Active-low NAND output; drives loads up to 24 mA sink at 3.3V, with VOL ≤0.55 V. |
| 7 | GND | Ground reference for all logic and power domains; must be low-impedance for noise immunity. |
| 14 | VCC | Single supply rail; powers internal logic and output stage; supports dynamic voltage scaling. |
Key Features
| Feature | Design Value |
|---|---|
| IOFF Partial Power-Down | Automatically disables outputs when VCC = 0V, blocking reverse current flow between live and unpowered subsystems. |
| Voltage Translation | Accepts 3.3V or 5V inputs while operating from 1.8V–3.3V supplies-enables seamless interface between legacy and modern logic families. |
| Low Dynamic Power | Typical Cpd = 18 pF per gate at 3.3V - reduces switching power consumption in high-frequency enable/control paths. |
| Robust ESD Immunity | 2 kV HBM, >1 kV CDM - eliminates need for external transient suppression in most industrial PCB layouts. |
| Wide Temp Operation | Specified from –40°C to +125°C - supports deployment in automotive under-hood, industrial motor drives, and outdoor edge nodes. |
Applications
| Industrial PLC I/O Isolation | USB Hub Power Control |
|---|---|
Use Scenario: Isolating 24V digital input modules from 3.3V microcontroller GPIO during controller sleep mode. IC Role / Device Role / Timing Role: NAND gate configured as active-low enable latch; IOFF prevents backfeed from 24V optocoupler outputs into MCU I/O. Use Value: Eliminates need for discrete MOSFET isolators or dedicated level translators, reducing BOM count and layout area by 30%. | Use Scenario: Controlling USB VBUS power sequencing in multi-port hubs where upstream port must power downstream ports only after enumeration. IC Role / Device Role / Timing Role: Logic gate implementing AND-OR enable tree; uses 5.5V-tolerant inputs to monitor both 5V VBUS and 3.3V controller status signals. Use Value: Ensures strict power-up order compliance per USB 2.0 specification without adding delay elements or microcontroller firmware overhead. |
| Laptop Keyboard Backlight Enable | Smart Meter Communication Interface |
Use Scenario: Driving white LED backlight strings via constant-current driver enable lines, synchronized with keyboard scan timing. IC Role / Device Role / Timing Role: NAND gate used as inverted enable buffer; operates from 1.8V system rail while accepting 3.3V scan-line signals. Use Value: Enables direct interface between ultra-low-power keyboard controllers and higher-voltage LED drivers, avoiding level-shifter ICs and associated quiescent current. | Use Scenario: Isolating RS-485 transceiver enable lines from microcontroller UART pins during deep-sleep modes in battery-powered smart meters. IC Role / Device Role / Timing Role: Gate providing controlled shutdown of transceiver bias circuits; IOFF blocks leakage that would otherwise drain coin-cell backup power. Use Value: Extends battery life by >2 years in meter sleep mode by limiting IOFF leakage to <20 µA over full temperature range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC00APW | TSSOP-14, identical logic function and IOFF spec, but TI version has slightly higher ICC (max 40 µA vs Diodes' 40 µA) and same 3.5 ns tPD at 3.3V. | No functional difference in voltage translation or power-down behavior; pinout and footprint identical. | Select when TI-qualified supply chain or dual-sourcing is required; no redesign needed. |
| 74AHC00PW,118 | NXP variant with wider VCC range (2V–5.5V), higher speed (2.5 ns tPD at 5V), but no IOFF and only 5.5V input tolerance-not 5.5V tolerant at 2V VCC. | Not suitable for partial power-down systems; requires external isolation if used in hot-swap or multi-rail environments. | Choose only for pure 5V or high-speed 3.3V designs where IOFF is unnecessary and lower propagation delay is critical. |
Compared with SN74LVC00APW, the 74LVC00AT14-13 offers identical form-fit-function and superior supply-chain traceability for industrial OEMs; versus 74AHC00PW, it provides essential IOFF protection and broader low-voltage operation (1.65V), making it the only viable choice for battery-backed or mixed-rail embedded systems.

FAQ
What is the maximum input voltage the 74LVC00AT14-13 can tolerate when VCC = 1.8V?
The device accepts input voltages up to 5.5V regardless of VCC level, including at 1.8V supply. This is explicitly guaranteed in the Absolute Maximum Ratings table and confirmed in the "Inputs accept up to 5.5V" feature statement-enabling safe interfacing with higher-voltage signals without external clamping diodes or resistors.
Does the 74LVC00AT14-13 support hot insertion into a live backplane?
Yes-its IOFF circuitry ensures outputs enter high-impedance state when VCC = 0V, limiting backdrive current to ≤20 µA across –40°C to +125°C. This meets hot-swap requirements for industrial backplanes where unpowered cards may connect to powered buses, preventing damage to upstream drivers or power rails.
Can this device replace a 74HC00 in an existing 5V design?
Yes, with qualification: the 74LVC00AT14-13 operates at 5V (within its 1.65V–5.5V range), matches HC00 pinout and logic function, and offers improved 5.5V input tolerance and IOFF. However, verify timing margins-propagation delay is faster (4.1 ns typ at 5V vs ~15 ns for HC00), which may affect setup/hold in synchronous circuits.
Is the TSSOP-14 package of 74LVC00AT14-13 RoHS and halogen-free compliant?
Yes-the datasheet confirms full RoHS 2015/863/EU (RoHS 3) compliance, zero intentionally added lead, and halogen/antimony-free "Green" status (<900 ppm Br, <900 ppm Cl, <1000 ppm Sb). This is documented in Features section Notes 1–3 and verified in Diodes' official product definitions portal.
