Nexperia USA Inc. 74LVC2G07GV,125

Overview

74LVC2G07GV,125 from Nexperia is a dual non-inverting buffer with open-drain outputs, designed for level translation between 3.3 V and 5 V logic domains. It features Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and operates from 1.65 V to 5.5 V supply. Used in I²C bus pull-up interfaces, GPIO expansion, and mixed-voltage signal conditioning.

For engineers reviewing the 74LVC2G07GV,125 datasheet, 74LVC2G07GV,125 pinout, 74LVC2G07GV,125 application, or 74LVC2G07GV,125 equivalent, key selection criteria include open-drain drive strength at 3.0 V (–24 mA), input overvoltage tolerance to 5.5 V, IOFF-enabled backflow prevention during power sequencing, and –40 °C to +125 °C industrial temperature rating.

Technical Context

This device implements two independent open-drain buffers with Schmitt-trigger inputs, enabling robust operation with slow-rising or noisy signals. Each channel supports bidirectional voltage translation via external pull-up resistors, with input thresholds scaling with VCC (e.g., VIH = 0.7 × VCC at 4.5–5.5 V).

The IOFF circuit actively disables output terminals when VCC = 0 V, blocking reverse current flow into powered subsystems - critical for hot-swap and partial-power-down architectures. Static and dynamic characteristics are fully specified across –40 °C to +125 °C, with propagation delay as low as 0.5 ns at 5.5 V.

FAQ

Can 74LVC2G07GV,125 be used as a level shifter for UART signals?

No - UART requires push-pull drive for both high and low states, but 74LVC2G07GV,125 has open-drain outputs only. It can drive UART TX lines only if the receiver has a pull-up and interprets open-drain low as logic 0 and pulled-high as logic 1; however, this violates RS-232/TTL voltage standards and risks timing violations due to RC rise time. Use dedicated UART level shifters instead.

What is the maximum recommended pull-up resistor value for 1Y/2Y at 3.3 V supply?

At VCC = 3.3 V and IO = –24 mA, VOL ≤ 0.55 V per datasheet Table 7. To ensure VOL stays below 0.4 V (for 10% noise margin), use RPULL-UP ≤ (3.3 V − 0.4 V) / 0.024 A ≈ 121 kΩ. For 400 kHz I²C, 2.2 kΩ is typical; for static GPIO, up to 10 kΩ maintains fast fall time (<100 ns) while limiting power.

Does the IOFF feature work when VCC is floating (not connected)?

No - IOFF activates only when VCC is at 0 V (grounded). If VCC is floating, internal bias networks may not disable the output FETs reliably, risking undefined output state and potential backfeed. Always tie VCC to GND or a defined voltage during power-down; never leave it floating.

Is 74LVC2G07GV,125 qualified for automotive applications?

No - this variant is rated for –40 °C to +125 °C but is not AEC-Q200 qualified. Nexperia offers automotive-grade versions (e.g., 74LVC2G07GV-Q100) with enhanced testing, lot traceability, and PPAP documentation. Use only Q100 parts in safety-critical or vehicle-mounted systems.
