onsemi NLVVHC1G09DFT1G

Overview

NLVVHC1G09DFT1G from onsemi is a single 2-input AND gate with open-drain output, designed for level-shifting and wired-OR logic in mixed-voltage systems. It operates from 2.0 V to 5.5 V, delivers 4.3 ns propagation delay at 5 V (typ), supports ±8 mA I_O at 3.0 V, and features overvoltage-tolerant inputs/outputs up to 5.5 V - enabling reliable interfacing between 3 V and 5 V domains in industrial control I/O modules.

For engineers reviewing the NLVVHC1G09DFT1G datasheet, pinout, applications, or equivalent options, key selection criteria include open-drain compatibility with pull-up networks, IOFF partial power-down protection, voltage translation capability, and SC-88A package suitability for space-constrained PCB layouts.

Technical Context

The NLVVHC1G09DFT1G implements standard positive-logic AND functionality with an open-drain output stage, requiring an external pull-up resistor to define high-level voltage and logic threshold. Its input structure tolerates voltages up to 5.5 V independent of V_CC, allowing safe connection to higher-voltage buses even when powered at 2.0 V.

IOFF circuitry disables input leakage paths when V_CC = 0 V, preventing back-powering and signal contention during hot insertion or partial power-down sequences. The device uses silicon-gate CMOS technology with chip complexity under 100 FETs, achieving TTL-compatible speed while maintaining CMOS low static power consumption.

FAQ

What logic function does the NLVVHC1G09DFT1G implement?

The NLVVHC1G09DFT1G implements a standard 2-input positive-logic AND function with an open-drain output stage. When both inputs A and B are HIGH, the output Y is pulled LOW through the internal NMOS transistor; otherwise, Y remains in high-impedance state and requires an external pull-up resistor to define the HIGH voltage level. This architecture enables wired-OR bus configurations and flexible voltage-level translation.

Can the NLVVHC1G09DFT1G safely interface a 5 V signal to a 3.3 V microcontroller?

Yes - the NLVVHC1G09DFT1G supports input voltages up to 5.5 V regardless of V_CC level, so it can accept 5 V logic signals while powered from a 3.3 V rail. Its overvoltage-tolerant inputs eliminate the need for external level-shifting components, and its open-drain output allows the pull-up resistor to be tied to the 3.3 V domain, ensuring safe and compliant interfacing between the two voltage domains.

Does the NLVVHC1G09DFT1G support partial power-down operation?

Yes - the NLVVHC1G09DFT1G includes IOFF circuitry that disables input leakage paths when V_CC = 0 V. This feature prevents back-powering of the supply rail and avoids signal contention on shared buses during hot insertion, system sleep states, or partial power-down sequences - a critical capability for modular industrial and automotive electronics where subsystems may power up/down independently.

What is the maximum output sink current specification for the NLVVHC1G09DFT1G?

The NLVVHC1G09DFT1G is rated to sink up to 8 mA at V_CC = 3.0 V and up to 25 mA absolute maximum per output pin. At 5.5 V V_CC, the typical sink current is 16 mA. These values are verified across the full operating temperature range (−55 °C to +125 °C), making the NLVVHC1G09DFT1G suitable for driving LEDs, optocouplers, and logic inputs with margin in demanding industrial and automotive applications.

Which package type is used by the NLVVHC1G09DFT1G, and what are its key mechanical attributes?

The NLVVHC1G09DFT1G uses the SC-88A (also known as SOT-353) package: a 5-pin, surface-mount, lead-free outline measuring 2.0 mm × 1.25 mm with 0.65 mm pin pitch. It features gull-wing leads, conforms to JEDEC MO-178 standards, and is qualified for reflow soldering per J-STD-020. This compact footprint supports high-density PCB layouts in space-constrained applications such as portable instrumentation and automotive ECUs.
