Product details
Overview
74LVC1G00SE-7 from Diodes Incorporated is a single 2-input positive NAND gate in SOT353 package, operating from 1.65V to 5.5V supply, with ±24mA output drive at 3.3V, 5.5V-tolerant inputs, and IOFF partial power-down protection. It serves as a level-shifting logic gate in mixed-voltage I/O interfaces of portable computing peripherals.
For engineers reviewing the 74LVC1G00SE-7 datasheet, 74LVC1G00SE-7 pinout, 74LVC1G00SE-7 application, or 74LVC1G00SE-7 equivalent, key selection criteria include supply voltage flexibility (1.65–5.5V), 3.3V-compatible output drive strength, IOFF-enabled signal isolation during power sequencing, and SOT353 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements standard positive-logic NAND Boolean function (Y = A·B) using CMOS technology, with push-pull output stage enabling direct TTL-level interfacing. Its IOFF circuit actively disables outputs when VCC = 0V, preventing back-current flow in partial-power-down systems.
Input tolerance up to 5.5V allows safe connection to higher-voltage buses while powered from lower supplies (e.g., 1.8V or 3.3V), and propagation delay ranges from 0.5ns (min) to 6.0ns (max) at 3.3V across –40°C to +125°C, supporting reliable timing in high-speed digital control paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G00DBVR | Same logic function and IOFF, but in SOT23-5 (3.0×2.8mm); 204°C/W θJA vs. 371°C/W for SOT353 | Higher thermal performance suits continuous 24mA drive in ambient >85°C environments | Select when board layout permits larger footprint and thermal management is critical |
| 74LVC1G00Z-7 | Identical electrical specs, but in smaller SOT553 (1.6×1.6mm, 0.5mm pitch); 231°C/W θJA | Better space efficiency for ultra-dense mobile PCBs where 0.65mm pitch is prohibitive | Select when miniaturization outweighs rework accessibility and thermal derating needs |
Compared with SN74LVC1G00DBVR, the 74LVC1G00SE-7 trades thermal headroom for 30% smaller area; versus 74LVC1G00Z-7, it offers superior solder joint reliability at 0.65mm pitch while maintaining identical logic behavior and voltage tolerance.

FAQ
Can 74LVC1G00SE-7 operate reliably at 1.65V supply?
Yes. The device is fully characterized down to 1.65V, with guaranteed VOL ≤0.45V and VOH ≥0.95V at –40°C to +85°C under 4mA load. Propagation delay remains within 8.0ns max at this voltage, supporting functional operation in ultra-low-power subsystems.
What is the purpose of the NC pin on SOT353?
Pin 6 is internally unconnected and must be left floating or tied to GND per Diodes' layout recommendations. It is not a thermal pad or test point; routing copper to it may cause parasitic coupling or solder wicking issues without electrical benefit.
Does IOFF functionality require external biasing?
No. IOFF activates automatically when VCC drops below ~0.8V - no external control signal or pull-up/down is needed. The output enters high-impedance state with leakage limited to ±10μA, protecting downstream circuits during power ramp-down.
How does 74LVC1G00SE-7 compare to older 74HC logic in mixed-voltage systems?
Unlike 74HC, which fails above 6V and lacks 5.5V-tolerant inputs, the 74LVC1G00SE-7 safely interfaces 5V signals while powered from 1.8V or 3.3V. Its IOFF feature also eliminates the need for external isolation MOSFETs required by HC-series in partial-power-down scenarios.
