Diodes Incorporated 74LVCE1G07FZ4-7

Overview

74LVCE1G07FZ4-7 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 circuitry for partial power-down protection. It is used in PC peripherals, set-top boxes, and GPS modules where rail-to-rail interfacing and bus-wired logic are required.

For engineers reviewing the 74LVCE1G07FZ4-7 datasheet, 74LVCE1G07FZ4-7 pinout, 74LVCE1G07FZ4-7 application, or 74LVCE1G07FZ4-7 equivalent, this page provides verified functional identity, DFN1410 package mapping, open-drain timing behavior, IOFF-enabled power-down isolation, and direct TTL/CMOS interface capability - all confirmed from Diodes Incorporated's DS32275 Rev. 2-2.

Technical Context

This device implements a single non-inverting buffer with open-drain output, enabling wired-AND and wired-OR logic configurations when multiple outputs share a common pull-up. Its IOFF circuit disables both output paths during power-down, preventing back-current flow even when input signals remain active at up to 5.5 V.

The DFN1410 package (1.4 mm × 1.0 mm) uses internally connected pins 2 and 5 per datasheet Note 2, supporting high-density PCB layouts. Propagation delay is 0.8–3.1 ns across 1.5–5.0 V supply range (CL = 15 pF), with input transition rate tolerance down to 5 ns/V at 5 V.

FAQ

Can 74LVCE1G07FZ4-7 drive a 10 kΩ pull-up resistor on a 3.3 V bus?

Yes. With 32 mA maximum sink current at 4.5 V and 24 mA at 3.3 V, the device can fully pull down a 10 kΩ pull-up on a 3.3 V bus (requiring only 0.33 mA), resulting in VOL ≤ 0.4 V per datasheet Table 4. This ensures solid logic-low margin (>2.9 V noise immunity) and fast rise/fall times due to low output capacitance (5 pF).

Does the DFN1410 package support reflow soldering per IPC-J-STD-020?

Yes. The 74LVCE1G07FZ4-7 DFN1410 package is qualified for standard lead-free reflow profiles (peak temperature 260°C, 20–40 sec above 217°C). Diodes' AP02001 land pattern recommendation and wettable flank leads ensure coplanarity control and post-reflow solder joint inspection capability - critical for automated optical inspection in high-volume manufacturing.

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

The IOFF circuit actively disables the output NMOS transistor, limiting leakage to ±10 μA (per datasheet Table 3). No damaging back-current flows from the 3.3 V input into the unpowered VCC rail. This behavior is verified under partial power-down conditions and distinguishes the LVCE family from standard LVC buffers that lack IOFF.

Is the NC pin (Pin 6) required to be grounded?

No. Pin 6 is unconnected internally and must remain floating or optionally tied to GND solely for mechanical reinforcement - not for electrical function. Grounding it adds no benefit and risks unintended shorting if layout misalignment occurs. Diodes' recommended land pattern treats it as non-functional, and no electrical specification depends on its state.
