Diodes Incorporated 74LVC1G04FW5-7

Overview

74LVC1G04FW5-7 from Diodes Incorporated is a single CMOS inverter gate with push-pull output, designed for 1.65V–5.5V supply operation and 5.5V-tolerant inputs. It delivers ±24mA output drive at 3.3V, supports partial power-down via IOFF, and operates across –40°C to +125°C ambient temperature. It is used in voltage level shifting and power-down signal isolation within compact portable electronics.

For engineers reviewing the 74LVC1G04FW5-7 datasheet, 74LVC1G04FW5-7 pinout, 74LVC1G04FW5-7 application, or 74LVC1G04FW5-7 equivalent, key selection criteria include supply voltage range, IOFF leakage (<±10μA), propagation delay (0.5–5.5ns at 3.3V), thermal resistance (θJA = 435°C/W), and DFN1010-6 (Type B) package compatibility with high-density PCB layouts.

Technical Context

This device implements a single positive-logic inverter (Y = A̅) using advanced CMOS process technology. Its IOFF circuit actively disables outputs during power-down to prevent backflow current, enabling safe use in mixed-voltage and hot-swap systems.

Input tolerance up to 5.5V allows interfacing with legacy 5V logic while powered from 1.8V or 3.3V rails. The X1-DFN1010-6 (Type B) package features 0.35mm pad pitch and six terminals - including two NC pins - optimized for space-constrained mobile and wearable applications.

FAQ

Can 74LVC1G04FW5-7 operate reliably at 1.65V supply?

Yes. The device is fully specified from 1.65V to 5.5V, with guaranteed VOH ≥ VCC – 0.1V and VOL ≤ 0.45V at 1.65V under 4mA load. Propagation delay remains within 7.5ns max across this range, supporting functional operation in low-power modes.

What is the purpose of the two NC pins in the X1-DFN1010-6 (Type B) package?

The two NC pins (Pins 3 and 5) have no internal connection and serve mechanical and thermal roles: they improve solder joint reliability, enhance thermal dissipation through additional copper area, and provide symmetry for consistent reflow behavior - not for electrical routing.

Does IOFF functionality require external biasing or control signals?

No. IOFF activates automatically when VCC is at 0V or near-ground; no external enable/disable signal is needed. The output enters high-impedance state with <±10μA leakage, preventing current backflow into powered sections without design overhead.

How does the 74LVC1G04FW5-7 handle input signals exceeding VCC?

Inputs tolerate up to 5.5V regardless of VCC value due to integrated clamping structures. This allows safe interfacing with 5V devices while operating from 1.8V or 3.3V supplies - no external resistors or diodes are required for level translation.
