Diodes Incorporated 74LVC1G00W5-7

Overview

74LVC1G00W5-7 from Diodes Incorporated is a single 2-input positive NAND gate in SOT25 package, operating from 1.65V to 5.5V supply, delivering ±24mA output drive at 3.3V, with 5.5V-tolerant inputs and IOFF partial power-down protection. It serves as a level-shifting logic gate in mixed-voltage digital interfaces of portable computing and consumer electronics.

For engineers reviewing the 74LVC1G00W5-7 datasheet, 74LVC1G00W5-7 pinout, 74LVC1G00W5-7 application, or 74LVC1G00W5-7 equivalent, key selection criteria include supply voltage flexibility (1.65–5.5V), 5.5V input tolerance for inter-rail compatibility, IOFF-enabled power-down isolation, propagation delay ≤4.7ns at 3.3V, and SOT25 footprint suitability for space-constrained PCB layouts.

Technical Context

This device implements standard positive-logic NAND functionality (Y = A·B) using CMOS technology with push-pull outputs. Its IOFF circuit actively disables output terminals during power-down, preventing back-current flow when VCC = 0V while inputs remain biased.

Input voltage tolerance up to 5.5V enables direct interfacing between 3.3V logic and 5V peripherals without external level shifters. The device meets JESD22 ESD specifications: >2000V HBM, >1000V CDM, and >200V MM, and exceeds 100mA latch-up immunity per JESD78 Class I.

FAQ

Can 74LVC1G00W5-7 operate reliably at 1.65V supply?

Yes. The device is fully specified down to 1.65V VCC, with guaranteed VOL ≤0.45V and VOH ≥0.95V at -40°C to +85°C under 4mA load. Propagation delay increases to 8.0ns at 1.8V, but remains functional and compliant per datasheet limits.

Does the SOT25 package include an exposed thermal pad?

No. The SOT25 package for 74LVC1G00W5-7 has standard gull-wing leads without an exposed thermal pad. Thermal resistance is θJA = 204°C/W on FR-4 with minimum recommended copper pour; no solder paste or thermal via design is required.

What is the maximum capacitive load this NAND gate can drive?

Based on measured Cpd = 23pF at 3.3V and tPD = 4.7ns, the gate reliably drives ≤30pF loads while maintaining timing integrity. For heavier loads (>50pF), propagation delay increases nonlinearly and output rise/fall times degrade; external buffering is recommended beyond that point.

Is IOFF functionality active when VCC = 0.5V?

Yes. IOFF activates when VCC drops below approximately 0.8V, disabling the output stage and limiting leakage to ±10μA even with inputs held at 5.5V. This behavior is verified across -40°C to +125°C and ensures safe operation during brown-out or controlled power-down sequences.
