Product details
Overview
74LVCE1G02FZ4 from Diodes Incorporated is a single 2-input positive NOR gate in DFN1410 package, operating from 1.4V to 5.5V supply, with ±24mA output drive at 3.3V, 5.5V-tolerant inputs, and IOFF-enabled partial power-down protection-used for voltage level shifting between mixed-voltage logic domains in portable consumer electronics.
For engineers reviewing the 74LVCE1G02FZ4 datasheet, 74LVCE1G02FZ4 pinout, 74LVCE1G02FZ4 application, or 74LVCE1G02FZ4 equivalent, key selection criteria include supply voltage flexibility (1.4–5.5V), 5.5V input tolerance, IOFF leakage <10μA, propagation delay ≤2.9ns at 3.3V/15pF, and DFN1410 thermal resistance (θJA = 430°C/W).
Technical Context
This CMOS NOR gate implements the Boolean function Y = A + B (positive-logic NOR) with totem-pole output stage and integrated IOFF circuitry that disables outputs during power-down to prevent backflow current. It supports mixed-voltage interfacing via 5.5V-tolerant inputs while powered from as low as 1.4V.
Switching performance is characterized across five supply voltages (1.5V–5V); at 3.3V/15pF, tPD is 0.6–2.9ns. Input transition rate is specified up to 20ns/V (VCC ≤3V), and Cpd is 23pF at 10MHz-enabling low-power, high-speed operation in battery-constrained designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4V to 5.5V - enables direct interface with 1.8V, 2.5V, 3.3V, and 5V logic families |
| Input Voltage Tolerance | Up to 5.5V - allows safe connection to higher-voltage signals without level shifters |
| Output Drive Strength | ±24mA at VCC = 3.3V - sufficient to drive multiple LVC/LVCE loads or small capacitive traces |
| Propagation Delay | ≤2.9ns at VCC = 3.3V, CL = 15pF - supports >300MHz toggle rates in clean signal paths |
| IOFF Leakage Current | <10μA at VI/VO = 5.5V - prevents damaging back-current during partial power-down sequencing |
| ESD Protection | 2kV HBM, 200V MM - exceeds JEDEC JESD22-A114/A115 requirements for board-level robustness |
| Operating Temperature | –40°C to +85°C - qualified for commercial and industrial ambient environments |
Pinout & Package
DFN1410 (1.4mm × 1.0mm, 0.5mm pitch, 6-pin) with exposed thermal pad. Pin 2 and Pin 5 are internally connected (NC and GND tie). Package complies with RoHS and uses halogen-free molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Data Input | Primary logic input; 5.5V-tolerant, compatible with TTL and CMOS thresholds across full VCC range |
| B | Data Input | Secondary logic input; identical electrical specs to Pin A; both must be terminated to VCC or GND if unused |
| GND | Ground Reference | Return path for supply and signals; connects to internal substrate and thermal pad for heat dissipation |
| Y | Data Output | Inverting NOR output (Y = NOT(A OR B)); drives loads up to ±24mA with rail-to-rail swing |
| VCC | Power Supply | Core supply input; supports 1.4–5.5V; powers internal logic and output stage |
| NC | No Connect | Pin 6 is unconnected; electrically isolated and not bonded-must remain floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Extended VCC range (1.4–5.5V) | Enables single logic device to bridge 1.8V microcontrollers and 5V peripherals without external translators |
| IOFF partial power-down support | Prevents current backflow when VCC = 0V while inputs remain active-critical for hot-swap and multi-rail systems |
| 30% speed improvement over LVC at 1.8V | Reduces propagation delay to ~1.3ns (vs ~1.8ns for LVC), improving timing margin in low-voltage FPGA/CPLD interfaces |
| ±24mA drive at 3.3V | Drives 10+ LVC inputs or 15pF trace capacitance with <3ns delay-eliminates need for buffer stages in compact layouts |
| 5.5V-tolerant inputs | Accepts 5V signals while powered from 1.4V–3.3V rails-simplifies interconnect in mixed-supply SoC subsystems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G02DBVR | Same 5-pin SOT-23 package; VCC range 1.65–5.5V; no IOFF; 24mA drive at 3.3V; 3.5ns max tPD @3.3V/15pF | Lacks IOFF-unsuitable for partial power-down systems; requires external isolation for hot-swap use cases | Select when board-level power sequencing is fully controlled and cost is prioritized over safety-critical isolation |
| 74AUP1G02GW,125 | DFN1010-6 package; VCC 0.8–3.6V; 4mA drive at 3.3V; 3.8ns tPD @3.3V/15pF; IOFF supported | Lower drive strength and narrower VCC range limits use to ultra-low-power 1.8V/3.3V-only systems | Select only for battery-powered devices requiring <1μA ICC and where 4mA drive suffices for local gating |
Compared with SN74LVC1G02DBVR and 74AUP1G02GW,125, the 74LVCE1G02FZ4 uniquely combines wide VCC (1.4–5.5V), 5.5V input tolerance, IOFF, and ±24mA drive-making it the only option for mixed-voltage, hot-swap-capable NOR logic in space-constrained DFN layouts.

FAQ
What is the maximum input voltage the 74LVCE1G02FZ4 can tolerate when VCC = 1.4V?
The device accepts input voltages up to 5.5V regardless of VCC level, enabling safe connection to higher-voltage signals even when powered from 1.4V. This is achieved via internal input protection clamps and verified per JESD22-A114 (2kV HBM) and absolute maximum ratings (VI = –0.5V to 6.5V).
Does the DFN1410 package of the 74LVCE1G02FZ4 require solder paste stencil adjustments compared to SOT25?
Yes-the DFN1410 (1.4mm × 1.0mm, 0.5mm pitch) requires a 0.12mm-thick stencil with 0.25mm × 0.35mm apertures for the six perimeter pads and a 0.40mm × 0.40mm aperture for the thermal pad. Diodes' AP02001 recommends 50% area ratio for reliable reflow and void minimization.
How does IOFF functionality behave during VCC ramp-up or ramp-down transitions?
IOFF activates automatically when VCC drops below ~0.8V and deactivates when VCC rises above ~1.0V. During this transition window, output leakage remains <10μA, preventing back-current into powered-down sections-verified under partial power-down test conditions per JEDEC JESD78 Class II latch-up testing.
Can the 74LVCE1G02FZ4 drive a 50pF load at 3.3V while maintaining <5ns propagation delay?
Yes-propagation delay is 0.8–3.6ns at VCC = 3.3V ± 0.3V with CL = 50pF (per Figure 2 test condition), well within the 5ns requirement. The ±24mA drive capability ensures adequate slew rate into 50pF, and Cpd = 23pF confirms low dynamic power consumption at 10MHz.
