Nexperia USA Inc. 74LVC07ABQ,115

Overview

74LVC07ABQ,115 from Nexperia is a hex buffer IC with six independent open-drain outputs, designed for level translation between 1.2 V–5.5 V logic domains. It features Schmitt-trigger inputs for noise immunity, 5 V-tolerant I/O, and operates across –40 °C to +125 °C. Used in I²C bus pull-up, LED driving, and mixed-voltage interface circuits.

For engineers reviewing the 74LVC07ABQ,115 datasheet, 74LVC07ABQ,115 pinout, 74LVC07ABQ,115 application, or 74LVC07ABQ,115 equivalent, key selection criteria include open-drain drive strength (32 mA at 4.5 V), input hysteresis (typ. 0.3 V at 3.3 V), wide VCC range (1.2–5.5 V), and DHVQFN14 thermal performance.

Technical Context

The 74LVC07ABQ implements six identical unidirectional buffer stages, each with a Schmitt-trigger input and open-drain NMOS output stage. Input hysteresis enables robust operation with slow-rising signals, while the absence of internal pull-ups mandates external pull-up resistors for logic HIGH assertion.

All outputs support 5.5 V absolute maximum voltage on pins regardless of VCC, enabling safe interfacing with higher-voltage buses. The device complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36 across its full supply range.

FAQ

Can 74LVC07ABQ,115 drive an I²C bus directly?

Yes - its open-drain outputs and 5 V-tolerant pins allow direct connection to I²C SDA/SCL lines. External pull-up resistors must be used (typically 2.2 kΩ to 5 V). Propagation delays ≤3.5 ns ensure compliance with I²C Fast-mode (400 kHz) timing, and Schmitt inputs suppress noise-induced glitches during arbitration.

What is the role of the exposed thermal pad in the DHVQFN14 package?

It serves as a thermal interface, not an electrical connection. Per Nexperia's datasheet, it may remain floating or connect to GND for improved heat dissipation. No soldering is required, but if soldered, the land must be either floating or tied to GND - never left electrically unconnected and soldered.

Does 74LVC07ABQ,115 require external pull-up resistors on all outputs?

Yes - every open-drain output (1Y–6Y) requires an external pull-up resistor to define the HIGH logic state. The value depends on bus capacitance and desired rise time; for 100 pF and 1 μs rise time at 3.3 V, a 33 kΩ resistor is typical. No internal pull-ups exist.

How does Schmitt-trigger input behavior affect signal integrity?

It introduces hysteresis (≥0.3 V at 3.3 V), meaning the input threshold rises to ~1.8 V for LOW→HIGH transitions and falls to ~1.5 V for HIGH→LOW. This prevents oscillation on slow or noisy edges - critical for mechanical switches, long cables, or unfiltered sensor outputs - without adding external RC components.
