Diodes Incorporated 74LVCE1G00W5-7

Overview

74LVCE1G00W5-7 from Diodes Incorporated is a single 2-input positive NAND gate with totem-pole CMOS output, operating from 1.4V to 5.5V supply, featuring ±24mA drive at 3.3V, 5.5V-tolerant inputs, and IOFF-enabled partial power-down protection. It serves as a level-shifting logic buffer in mixed-voltage digital interfaces of portable computing and consumer electronics.

For engineers reviewing the 74LVCE1G00W5-7 datasheet, 74LVCE1G00W5-7 pinout, 74LVCE1G00W5-7 application, or 74LVCE1G00W5-7 equivalent, key selection criteria include supply voltage flexibility (1.4–5.5V), 5.5V input tolerance for inter-voltage-domain interfacing, IOFF functionality for hot-swap safety, propagation delay down to 0.6ns at 2.5V/15pF, and SOT25 package compatibility with high-density PCB layouts.

Technical Context

This device implements standard Boolean NAND logic (Y = A·B) using low-threshold CMOS process technology optimized for wide V_CC operation. Its IOFF circuit actively disables outputs during power-down, preventing back-current flow between powered and unpowered rails in partial-power-down systems.

Input thresholds are dynamically scaled with V_CC (e.g., VIH = 0.65×V_CC at 1.4–1.95V), enabling reliable switching across 1.4V–5.5V. Output drive strength scales with supply voltage-delivering –24mA/+24mA at 3.3V-and supports direct TTL-level interfacing without external pull-ups.

FAQ

Can the 74LVCE1G00W5-7 operate reliably at 1.4V supply?

Yes. The device is fully characterized from 1.4V to 5.5V, with guaranteed propagation delay ≤7.2ns at 1.5V/15pF and output drive ≥–3mA/+3mA at 1.4V. Input thresholds scale with V_CC, ensuring correct logic interpretation even at minimum supply.

What does IOFF functionality do during system power-down?

IOFF disables both output transistors when V_CC = 0V, presenting high-impedance state regardless of input voltage. This blocks reverse current flow from live inputs (e.g., 5V bus) into unpowered V_CC or GND rails, preventing latch-up or damage in hot-swap scenarios.

Is the SOT25 package of 74LVCE1G00W5-7 compatible with standard pick-and-place equipment?

Yes. The SOT25 (SC-74A) package has 0.65mm pitch, 1.25mm body width, and JEDEC-compliant land pattern (per AP02001). Its gull-wing leads and defined pin 1 marking ensure reliable automated assembly and AOI inspection in high-volume manufacturing.

How does input voltage tolerance up to 5.5V benefit system design?

It allows direct connection of the gate's inputs to 5V logic buses, microcontroller GPIOs, or sensor outputs without external level-shifting components. This reduces BOM count, PCB area, and signal integrity risk-especially critical in space-constrained portable electronics.
