Diodes Incorporated 74LVC1G07FW5-7

Overview

74LVC1G07FW5-7 from Diodes Incorporated is a single CMOS buffer/driver with open-drain output, designed for voltage-level shifting and signal isolation in mixed-voltage systems. It operates from 1.65V to 5.5V, tolerates 5.5V inputs, supports IOFF partial power-down mode, delivers up to 32mA sink current at 4.5V, and is packaged in X1-DFN1010-6 (Type B) for space-constrained logic interfacing in portable electronics.

For engineers reviewing the 74LVC1G07FW5-7 datasheet, 74LVC1G07FW5-7 pinout, 74LVC1G07FW5-7 application, or 74LVC1G07FW5-7 equivalent, key selection criteria include open-drain drive capability, 5.5V-tolerant input compatibility, IOFF-enabled power-down isolation, thermal resistance (θJA = 435°C/W), and DFN package solderability with NiPdAu terminations.

Technical Context

This device implements a single non-inverting buffer with open-drain output topology, enabling wired-OR/AND logic functions when multiple outputs share a common pull-up. Its IOFF circuit actively disables output leakage during VCC power-down, preventing backflow current into powered subsystems.

The input stage accepts voltages up to 5.5V independent of VCC, allowing seamless interface between 1.8V, 3.3V, and 5V domains. Propagation delay ranges from 0.5ns (min) to 8.5ns (max) across 1.8–5.0V supply and -40°C to +125°C ambient, with typical tPD = 2.3ns at 3.3V.

FAQ

What is the maximum allowable sink current for 74LVC1G07FW5-7 at 3.3V?

At VCC = 3.3V, the device supports up to 24mA sink current (IOL) while maintaining VOL ≤ 0.4V, as specified in the Recommended Operating Conditions table. This rating is validated across -40°C to +125°C ambient and applies to continuous DC loading, not pulsed conditions.

Can 74LVC1G07FW5-7 be used to translate a 5V signal to a 1.8V system?

Yes-the input is 5.5V-tolerant regardless of VCC level, so a 5V logic HIGH applied to pin 2 (A) will correctly register as HIGH when VCC = 1.8V. The output remains open-drain, so an external 1.8V pull-up is required to generate a 1.8V-compatible HIGH level at pin 6 (Y).

Does 74LVC1G07FW5-7 require external pull-up resistors?

Yes-its open-drain output (pin 6, Y) cannot drive a logic HIGH state internally. A pull-up resistor to the target logic rail (e.g., 3.3V or 5V) is mandatory for wired-OR operation or level translation. Typical values range from 2.2kΩ (for speed) to 10kΩ (for low power), depending on bus capacitance and rise-time requirements.

How does IOFF functionality protect the device during partial power-down?

When VCC = 0V, the IOFF circuit disables both input and output buffers, limiting leakage current to ±10μA even if 5.5V is present on A or Y pins. This prevents reverse current flow into powered subsystems, avoids unintended logic states, and satisfies JEDEC JESD78 latch-up immunity requirements (>100mA).
