Diodes Incorporated 74LVC1G06FW4-7

Overview

74LVC1G06FW4-7 from Diodes Incorporated is a single inverter 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 partial power-down via IOFF, and delivers up to 32mA sink current at 4.5V. Used in notebook I/O expansion, USB peripheral control, and power sequencing circuits.

For engineers reviewing the 74LVC1G06FW4-7 datasheet, 74LVC1G06FW4-7 pinout, 74LVC1G06FW4-7 application, or 74LVC1G06FW4-7 equivalent, this page provides verified package mapping (X2-DFN1010-6), confirmed open-drain logic behavior, IOFF-enabled power-down isolation, input voltage tolerance, and sink-current capability - all critical for level-shifting and wired-OR bus design.

Technical Context

This device implements a single CMOS inverter stage with an open-drain output stage, enabling active-low wired-OR and active-high wired-AND configurations when multiple outputs share a common pull-up. Its IOFF circuit disables both output FETs during power-down, preventing backflow current between powered and unpowered domains.

The input structure accepts voltages up to 5.5V regardless of VCC, allowing interoperability across 1.8V, 2.5V, 3.3V, and 5V logic domains. Propagation delay ranges from 0.5ns (5V) to 6.5ns (1.8V), with typical tPD of 2.3ns at 3.3V/25°C - optimized for low-latency interface buffering without rail-to-rail output drive.

FAQ

Can 74LVC1G06FW4-7 drive a 10kΩ pull-up to 5V?

Yes. With 32mA sink capability at 4.5V, the device easily handles 0.5mA load (5V/10kΩ) while maintaining VOL ≤ 0.55V. Measured VOL is 0.1V at 100μA and 0.55V at 32mA, confirming robust low-state margin across operating conditions.

What happens to the output when VCC = 0V and input A = HIGH?

The IOFF circuit disables both output FETs, placing Y in high-impedance state regardless of A's logic level. Output leakage remains ≤ ±200μA, preventing backfeed current into other powered rails - validated per JESD78 latch-up and IOFF test conditions.

Is the X2-DFN1010-6 package lead-free and RoHS compliant?

Yes. The 74LVC1G06FW4-7 is fully RoHS 2 compliant (2011/65/EU), with no purposely added lead, halogen-free (<900ppm Br+Cl), and antimony-free (<1000ppm). Compliance is certified per Diodes Incorporated's green product definition and documented in DS32272 Rev. 11-2.

How does propagation delay vary with supply voltage?

tpd decreases with higher VCC: 6.5ns at 1.8V, 4.0ns at 3.3V, and 3.0ns at 5.0V (–40°C to +85°C). This inverse relationship reflects faster transistor switching at elevated gate overdrive - confirmed by Figure 1 timing data in DS32272.
