Diodes Incorporated 74LVC1G00Z-7

Overview

74LVC1G00Z-7 from Diodes Incorporated is a single 2-input positive NAND gate in SOT553 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 compact portable electronics requiring low-voltage compatibility and signal isolation during sleep modes.

For engineers reviewing the 74LVC1G00Z-7 datasheet, 74LVC1G00Z-7 pinout, 74LVC1G00Z-7 application, or 74LVC1G00Z-7 equivalent, key selection criteria include its 1.65–5.5V VCC range, 0.5mm pitch SOT553 footprint, IOFF-enabled power-down isolation, and 4.7ns max propagation delay at 3.3V for timing-critical interface logic.

Technical Context

This device implements standard positive-logic NAND functionality (Y = A·B) with push-pull CMOS output stage and full 5.5V input tolerance-enabling direct interfacing between 1.8V/2.5V/3.3V/5V domains without external level shifters. Its IOFF circuit actively disables output leakage when VCC = 0V, preventing back-current in mixed-supply systems.

Designed for partial-power-down operation, it meets JESD22 ESD ratings (>2000V HBM, >1000V CDM), supports latch-up immunity >100mA per JESD78 Class I, and maintains stable switching performance across –40°C to +125°C ambient temperature.

FAQ

Can 74LVC1G00Z-7 operate reliably at 1.65V VCC?

Yes. The device is fully characterized down to 1.65V VCC per its Recommended Operating Conditions table, with guaranteed VOL ≤0.45V at 4mA load and tpd ≤8.0ns at 1.8V. At 1.65V, VIH is specified as 0.65×VCC (≥1.07V), ensuring robust noise margins in low-voltage systems.

Does the SOT553 package include an exposed thermal pad?

No. The SOT553 package used for 74LVC1G00Z-7 has five perimeter leads only and no exposed thermal pad. Thermal dissipation relies on copper traces connected to pins 2 (GND) and 3 (VCC); θJA is rated at 231°C/W under standard JEDEC test conditions.

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

Based on Cpd = 23pF (typ) at 3.3V and tpd = 4.7ns (max), the gate can reliably drive ≤30pF loads while maintaining specified timing. Driving >50pF may increase propagation delay beyond datasheet limits and require output series termination to suppress ringing.

Is IOFF functionality active when VCC is floating or undefined?

No. IOFF is triggered only when VCC is near 0V (≤0.2V). If VCC is floating, the internal power-on-reset circuitry does not activate IOFF, and the output enters high-impedance unpredictably. Always tie VCC to ground or use a pull-down resistor if intentional power-down is required.
