Nexperia USA Inc. 74LVC07AD,112

Overview

74LVC07AD from Nexperia is a hex buffer IC with six independent open-drain outputs, designed for level translation between 3.3 V and 5 V logic domains. It features Schmitt-trigger inputs for noise immunity, operates from 1.2 V to 5.5 V supply, supports -40 °C to +125 °C ambient range, and delivers ≤2.6 ns propagation delay at 5 V - used in I²C bus pull-up control and mixed-voltage GPIO interfacing.

For engineers reviewing the 74LVC07AD datasheet, 74LVC07AD pinout, 74LVC07AD application, or 74LVC07AD equivalent, key selection criteria include open-drain drive capability (32 mA sink at 4.5 V), 5 V-tolerant inputs, JEDEC-compliant voltage ranges (JESD8-7A/5A/C), and SO14 package thermal performance up to 125 °C.

Technical Context

This device implements six identical unidirectional buffer stages, each with Schmitt-trigger input hysteresis (typ. 0.3 V at 3.3 V) and open-drain NMOS output stage. Input thresholds scale with VCC per JEDEC standards, enabling reliable operation across 1.2 V–5.5 V supply rails without external biasing.

The output stage lacks internal pull-up; external resistors define logic-high levels and slew rate. Propagation delays are asymmetric: tPLZ (LOW→OFF) and tPZL (OFF→LOW) both specified down to 0.5 ns minimum, supporting high-speed bidirectional bus arbitration in protocols like SMBus.

FAQ

Can 74LVC07AD drive a 10 kΩ pull-up resistor on a 5 V I²C bus?

Yes. With 32 mA sink capability at 0.55 V output, the device easily pulls down a 10 kΩ resistor to <0.5 V at 5 V - well within I²C LOW threshold (0.3 × VDD). Rise time will be ~RC-limited (~50 ns), compatible with 400 kHz operation.

Does 74LVC07AD require external pull-up resistors on all six outputs?

Yes. All six outputs are open-drain NMOS structures with no internal pull-up. Each output must connect to a defined voltage rail (e.g., 3.3 V or 5 V) via an external resistor to establish HIGH logic level and control rise time.

What is the maximum capacitive load the 74LVC07AD can drive reliably?

Based on dynamic characteristics and CPD = 7.2 pF (VCC = 3.0–3.6 V), the device maintains <3.6 ns propagation delay with ≤50 pF load. Exceeding this increases delay and may cause timing violations in high-speed buses like SMBus.

Is the GND pin (pin 7) electrically connected to the exposed pad in SO14 package?

No. The SO14 (SOT108-1) package has no exposed thermal pad. Pin 7 is the sole GND connection; no additional thermal land or soldering is required or recommended for this variant.
