Nexperia USA Inc. 74LVC1G07GW,165

Overview

74LVC1G07GW,165 from Nexperia is a single non-inverting buffer with open-drain output, designed for level translation between 1.65 V–5.5 V logic domains. It features Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and −24 mA sink capability at VCC = 3.0 V. Used in I²C bus pull-up control, GPIO expansion interfaces, and mixed-voltage microcontroller peripheral buffering.

For engineers reviewing the 74LVC1G07GW,165 datasheet, 74LVC1G07GW,165 pinout, 74LVC1G07GW,165 application, or 74LVC1G07GW,165 equivalent, key selection criteria include open-drain drive strength, IOFF leakage during power sequencing, input overvoltage tolerance to 5.5 V, and guaranteed operation from −40 °C to +125 °C in TSSOP5 packaging.

Technical Context

This device implements a CMOS-based single-buffer architecture with Schmitt-trigger input hysteresis (typ. 0.3 V at VCC = 3.3 V), enabling robust operation with slow-rising signals. Its IOFF circuit actively disables the output stage when VCC = 0 V, limiting backflow current to ±2 μA.

The open-drain output supports wired-AND configurations and external pull-up flexibility across voltage domains. Propagation delay ranges from 0.5 ns (VCC = 5.5 V) to 8.4 ns (VCC = 1.65 V, −40 °C to +85 °C), with input transition rate support up to 20 ns/V at low VCC.

FAQ

Can 74LVC1G07GW,165 drive an I²C bus directly without external components?

Yes - its open-drain output and 5.5 V-tolerant inputs allow direct connection to I²C SDA/SCL lines when paired with a single external pull-up resistor per line. At VCC = 3.3 V, it sinks 24 mA, supporting standard-mode (100 kHz) and fast-mode (400 kHz) buses with up to 400 pF total capacitance using a 2.2 kΩ pull-up to 3.3 V.

What happens to the output when VCC is disconnected?

When VCC = 0 V, the IOFF circuit disables the output NMOS, placing Y in a high-impedance state with leakage ≤±2 μA. This prevents backflow current from external pull-ups or driven buses into the unpowered device, protecting both the 74LVC1G07GW,165 and upstream circuitry during hot-swap or power sequencing events.

Is the Schmitt-trigger input compatible with slow-rising analog sensor signals?

Yes - the input hysteresis (≥0.3 V at VCC = 3.3 V) provides noise margin against EMI and contact bounce. With Δt/ΔV support up to 20 ns/V at low VCC, it reliably digitizes signals with rise times as slow as 200 ns (for 1 V swing), making it suitable for switch debouncing and thermistor comparator outputs without additional RC filtering.

Does the n.c. pin on the TSSOP5 package require PCB routing or grounding?

No - Pin 1 is explicitly designated "n.c." (no connection) in Nexperia's datasheet and has no internal bond wire or silicon connection. It must remain unconnected on the PCB; neither routing nor grounding is permitted, as doing so may compromise package mechanical integrity or cause unintended parasitic coupling.
