Diodes Incorporated 74LVCE1G07W5-7

Overview

74LVCE1G07W5-7 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 1.65 V to 5.5 V, supports 5.5 V-tolerant inputs, delivers 32 mA sink current at 4.5 V, and features IOFF partial power-down protection. It is used in PC peripherals, set-top boxes, and GPS modules where bidirectional level translation or wired-AND logic is required.

For engineers reviewing the 74LVCE1G07W5-7 datasheet, 74LVCE1G07W5-7 pinout, 74LVCE1G07W5-7 application, or 74LVCE1G07W5-7 equivalent, this page provides verified electrical specs, SOT25 package details, IOFF behavior, open-drain interface constraints, and validated alternatives for level-shifting and power-down isolation use cases.

Technical Context

This device implements a non-inverting buffer with open-drain output, enabling active-low wired-OR and active-high wired-AND bus configurations. Its IOFF circuit disables output leakage during power-down, preventing back-current flow when VCC = 0 V while inputs remain biased up to 5.5 V.

The input threshold scales with VCC (e.g., VIH = 0.7×VCC at 4.5–5.5 V), ensuring TTL-compatible recognition across supply voltages. Propagation delay is 0.8–3.1 ns (VCC = 1.5–5 V, CL = 15 pF), and output low voltage remains ≤0.55 V at 32 mA sink load.

FAQ

Can the 74LVCE1G07W5-7 drive a 10 kΩ pull-up resistor on a 5 V bus?

Yes. With 32 mA sink capability at VCC = 4.5 V and VOL ≤ 0.55 V, it pulls the output below 0.5 V when sinking 0.5 mA (5 V / 10 kΩ), well within its rated performance. The device's 5.5 V-tolerant input also accepts 5 V control signals directly, eliminating level-shifter components.

What happens to the output when VCC = 0 V and an input is held at 3.3 V?

The IOFF circuit activates, disabling the output FET and limiting leakage to ±10 μA. This prevents back-current from the 3.3 V input source into the unpowered VCC rail, satisfying JEDEC JESD78 latch-up immunity requirements and protecting upstream drivers during hot-swap events.

Is the NC pin on the SOT25 package required to be left floating?

Yes. Pin 3 is internally unconnected; grounding or tying it to VCC introduces no functional benefit and may increase parasitic capacitance or ESD coupling risk. Diodes Incorporated's AP02001 pad layout recommends leaving it unconnected and avoiding solder mask openings over the pad.

How does the 74LVCE1G07W5-7 differ from standard 74LVC1G07 buffers in power-down behavior?

Unlike generic 74LVC1G07 variants, the "E" suffix denotes explicit IOFF characterization per JESD78 Class II (≥100 mA latch-up immunity) and guaranteed ±10 μA leakage at VCC = 0 V. Standard LVC versions lack this specification, making them unsuitable for systems requiring certified partial power-down safety.
