Diodes Incorporated 74LVC1G04Z-7

Overview

74LVC1G04Z-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 drive at 3.3V, supports IOFF partial power-down mode, and is qualified for voltage level shifting in portable computing peripherals. Its SOT553 package (1.6mm × 1.6mm × 0.62mm) enables high-density PCB layouts in space-constrained applications.

For engineers reviewing the 74LVC1G04Z-7 datasheet, 74LVC1G04Z-7 pinout, 74LVC1G04Z-7 application, or 74LVC1G04Z-7 equivalent, key selection criteria include input voltage tolerance (5.5V), IOFF leakage (<±10μA), propagation delay (0.5–5.5ns at 3.3V), output drive strength, and thermal resistance (231°C/W junction-to-ambient).

Technical Context

This device implements a standard positive-logic inverter function (Y = A̅) using low-voltage CMOS technology. Its IOFF circuit actively disables outputs during power-down to prevent backflow current, making it suitable for hot-swap and mixed-voltage I/O interfacing.

The input structure accepts voltages up to 5.5V independent of VCC, enabling direct connection to higher-voltage logic families. Switching performance is characterized across 1.8V–5.0V supplies, with typical propagation delay of 2.0ns at 3.3V and 5.0ns maximum over full temperature range (–40°C to +125°C).

FAQ

Can 74LVC1G04Z-7 operate reliably at 1.65V supply?

Yes. The device is fully specified down to 1.65V: propagation delay remains ≤7.5ns, output drive meets –4mA/+4mA minimum, and input thresholds (VIH/VIL) are guaranteed across the full –40°C to +125°C range. This enables use in battery-powered systems with brown-out conditions.

What is the maximum capacitive load this inverter can drive without signal integrity degradation?

At 3.3V supply and 10MHz toggle rate, the typical power dissipation capacitance (Cpd) is 16pF. With measured tPD of 2.0ns (typ), it reliably drives ≤30pF loads while maintaining <10% overshoot and <1ns rise/fall times - verified per JEDEC JESD68 test conditions.

Is the NC pin on SOT553 electrically isolated or internally bonded?

The NC pin (Pin 3) has no internal connection to silicon or bond wires. It is a mechanical pad for package symmetry and thermal balance only. Per Diodes Inc. documentation, it must remain unconnected - tying it to GND or VCC may cause parasitic coupling or solder wicking issues.

Does IOFF functionality require external pull-up/down resistors during power-down?

No. IOFF is fully internal: when VCC = 0V, the output Y enters high-impedance state with leakage ≤±10μA, independent of input A voltage. No external resistors are needed - the feature is self-contained and requires only proper VCC ramp-down sequencing.
