Nexperia USA Inc. 74LVC1G07GW-Q100H

Overview

74LVC1G07GW-Q100 from Nexperia is a single-channel CMOS buffer with open-drain output, designed for level translation between 3.3 V and 5 V logic domains in automotive systems. It features Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and operates across -40 °C to +125 °C with supply voltage from 1.65 V to 5.5 V. Used in CAN bus interface pull-up control and I²C bus buffering.

For engineers reviewing the 74LVC1G07GW-Q100 datasheet, 74LVC1G07GW-Q100 pinout, 74LVC1G07GW-Q100 application, or 74LVC1G07GW-Q100 equivalent, key selection criteria include open-drain drive strength (-24 mA at 3.0 V), AEC-Q100 Grade 1 qualification, IOFF-enabled power sequencing, and input overvoltage tolerance up to 5.5 V.

Technical Context

This device implements a non-inverting buffer with open-drain output stage, enabling wired-AND logic and bidirectional bus interfacing. Its Schmitt-trigger inputs accept slow-rising signals (Δt/ΔV ≤ 20 ns/V at 1.65–2.7 V) and tolerate input voltages beyond VCC up to 5.5 V.

The IOFF circuit actively disables the output when VCC = 0 V, blocking backflow current during partial power-down - critical for hot-swap and multi-rail automotive subsystems. Propagation delay ranges from 0.5 ns (min) to 8.4 ns (max) depending on VCC and temperature.

FAQ

What is the maximum sink current capability of the 74LVC1G07GW-Q100 at 5.0 V supply?

The device is characterized for -24 mA output drive at VCC = 3.0 V. At VCC = 5.0 V, the typical sink current exceeds -32 mA (per Table 7, VOL ≤ 0.55 V at IO = 32 mA), but absolute maximum rating is limited to ±50 mA per pin. Derating applies above 74 °C in TSSOP5 package.

Can the 74LVC1G07GW-Q100 be used to translate from 5 V inputs to a 1.8 V system?

No - the device does not provide level shifting from higher to lower VCC. Inputs are overvoltage tolerant up to 5.5 V regardless of VCC, but output high level is defined solely by the external pull-up voltage. To drive a 1.8 V bus, the pull-up must be connected to 1.8 V, and the 5 V input must be compatible with VIH ≥ 0.7×VCC = 1.26 V (which it is).

Does the IOFF feature require any external control signal?

No - IOFF is fully automatic and activated when VCC drops to 0 V. No enable/disable pin or external bias is needed. The output enters high-impedance state intrinsically, preventing back-current flow through the device during power sequencing or partial shutdown.

Is the Schmitt-trigger input hysteresis value specified in the datasheet?

Yes - hysteresis is implicit in the VIH and VIL specifications: minimum hysteresis = VIH(min) − VIL(max). For VCC = 3.3 V, VIH(min) = 2.0 V and VIL(max) = 0.8 V, yielding ≥1.2 V hysteresis. This ensures reliable switching in noisy 12 V vehicle environments with slow-rising signals.
