onsemi NL17VHC1G07DTT1G

Overview

NL17VHC1G07DTT1G from onsemi is a single non-inverting buffer with open-drain output, designed for level-shifting and wired-OR logic applications in mixed-voltage systems. It operates from 2.0 V to 5.5 V, delivers 3.5 ns typical propagation delay at 5 V, supports ±8 mA output drive 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 I/O and sensor signal conditioning circuits.

For engineers reviewing the NL17VHC1G07DTT1G datasheet, pinout, applications, or equivalent options, key selection criteria include its CMOS-level input thresholds, IOFF partial power-down protection, SC-74A (SOT-23-5) package compatibility, and verified 125 °C operating temperature range for embedded control and automotive body electronics.

Technical Context

The NL17VHC1G07DTT1G implements a single-stage CMOS buffer with open-drain output topology, requiring an external pull-up resistor to define high-level logic states. Its input structure tolerates voltages up to 5.5 V independent of VCC, allowing safe operation during hot insertion or battery-backup scenarios where supply rails may be unpowered.

IOFF circuitry actively disables input/output leakage paths when VCC = 0 V, preventing back-powering of upstream circuits. The device exhibits rail-to-rail input voltage range (0–5.5 V), low quiescent current (≤40 µA at 5.5 V), and guaranteed performance across −55 °C to +125 °C, meeting requirements for extended-temperature industrial and under-hood automotive subsystems.

FAQ

What is the input threshold type of NL17VHC1G07DTT1G?

NL17VHC1G07DTT1G uses CMOS-level input thresholds: VIH = 1.5 V minimum at 2.0 V VCC, scaling proportionally with supply voltage. This differs from TTL-threshold variants like MC74VHC1GT07. The fixed-ratio thresholds ensure predictable switching behavior across the full 2.0–5.5 V operating range, making NL17VHC1G07DTT1G ideal for stable logic-level translation in programmable logic controllers and sensor hubs where input noise immunity matters.

Does NL17VHC1G07DTT1G support hot-plug operation?

Yes, NL17VHC1G07DTT1G supports hot-plug operation due to its overvoltage-tolerant inputs and outputs rated to 5.5 V regardless of VCC state, plus IOFF protection that blocks current flow when VCC = 0 V. These features prevent latch-up or damage during live insertion into powered backplanes or modular I/O systems - a key requirement verified in onsemi's AEC-Q100 stress testing for automotive gateway modules and industrial fieldbus nodes using NL17VHC1G07DTT1G.

What is the maximum output sink current for NL17VHC1G07DTT1G at 3.3 V?

At 3.3 V VCC, NL17VHC1G07DTT1G guarantees a maximum output sink current (IOL) of 8 mA while maintaining VOL ≤ 0.44 V, per onsemi's DC Electrical Characteristics table. This allows direct driving of standard LEDs, small relays, or TTL inputs without external amplification. The 8 mA rating is validated across −55 °C to +125 °C, ensuring consistent performance in outdoor enclosures and engine compartments where NL17VHC1G07DTT1G is commonly deployed.

Can NL17VHC1G07DTT1G replace a 74LVC1G07 in existing designs?

NL17VHC1G07DTT1G can replace 74LVC1G07 in many cases but requires verification of input threshold compatibility and temperature requirements. While both are single open-drain buffers in SOT-23-5 packages, NL17VHC1G07DTT1G uses fixed CMOS thresholds (VIH = 1.5 V @ 2 V), whereas 74LVC1G07 uses VCC-referenced thresholds (VIH = 0.7×VCC). Also, NL17VHC1G07DTT1G is rated to −55 °C, unlike most LVC variants. Always confirm timing and drive strength match your NL17VHC1G07DTT1G application before substitution.

What package type does NL17VHC1G07DTT1G use?

NL17VHC1G07DTT1G uses the SC-74A package (also known as SOT-23-5), measuring 3.00 mm × 1.50 mm × 0.95 mm with 0.95 mm lead pitch. This compact, surface-mount package is RoHS-compliant and Pb-free, optimized for high-density PCB layouts in automotive ECUs and portable instrumentation. Pin 1 orientation follows Q4 marking convention per onsemi's ordering information - critical for automated placement accuracy when integrating NL17VHC1G07DTT1G into production assemblies.
