Diodes Incorporated 74LVC1G00FZ4-7

Overview

74LVC1G00FZ4-7 from Diodes Incorporated is a single 2-input positive NAND gate in X2-DFN1410-6 package, operating from 1.65V to 5.5V supply, with 5.5V-tolerant inputs and ±24mA output drive at 3.3V. It supports partial power-down via IOFF, enabling safe signal isolation in mixed-voltage systems such as USB interface level shifting and portable device power sequencing.

For engineers reviewing the 74LVC1G00FZ4-7 datasheet, 74LVC1G00FZ4-7 pinout, 74LVC1G00FZ4-7 application, or 74LVC1G00FZ4-7 equivalent, key selection criteria include supply voltage flexibility (1.65–5.5V), IOFF-enabled power-down protection, 3.3V/5V logic compatibility, and ultra-small 1.4mm × 1.0mm DFN footprint for space-constrained PCBs.

Technical Context

This device implements standard positive-logic NAND functionality (Y = A·B) with push-pull CMOS output stage and input clamp diodes enabling 5.5V tolerance regardless of VCC level. Its IOFF circuit actively disables outputs during power-down, preventing back-current flow between powered and unpowered rails.

Designed for low-power operation, it delivers typical propagation delay of 2.2ns at 3.3V and 25°C, with input capacitance of 5pF and power dissipation capacitance of 23pF at 10MHz - optimized for high-speed, low-noise digital interfacing in battery-powered and mixed-signal systems.

FAQ

Can 74LVC1G00FZ4-7 operate with VCC = 1.5V?

No. The recommended minimum operating voltage is 1.65V per DS32196 Rev. 11–2. At 1.5V, output drive strength degrades significantly, propagation delay increases beyond specification, and input threshold margins collapse - risking functional failure. Data retention is supported down to 1.5V, but not active logic operation.

Is the NC pin on 74LVC1G00FZ4-7 required to be grounded?

No. Pin 5 (NC) is internally unconnected and must remain floating per Diodes Inc. layout guidance. Grounding it may cause unintended parasitic coupling or violate thermal pad clearance rules. The recommended practice is to leave it unconnected and ensure no copper pour overlaps the pad.

What is the maximum capacitive load this device can drive reliably?

Based on switching characteristics and output drive data, 74LVC1G00FZ4-7 maintains specified tPD ≤6.0ns (at 3.3V) up to 30pF load capacitance. Driving >50pF causes measurable delay increase and potential waveform rounding; for heavier loads, add a series resistor or buffer stage per application note DN00012.

Does IOFF functionality require external biasing or control signals?

No. IOFF activates automatically when VCC = 0V - no external enable/disable pin or voltage monitor is needed. The internal circuitry senses VCC dropout and disables both output FETs simultaneously, limiting leakage to ±10μA. This behavior is intrinsic and requires no design modifications beyond proper power rail decoupling.
