Diodes Incorporated 74AUP1G02FW5-7

Overview

74AUP1G02FW5-7 from Diodes Incorporated is a single two-input positive NOR gate in the advanced ultra-low-power (AUP) CMOS logic family, designed for battery-powered portable electronics. It operates across 0.8V–3.6V supply, delivers ±4mA output drive at 3.0V, features IOFF for partial power-down protection, and includes Schmitt-trigger inputs with ~250mV hysteresis at 3.0V. It is used in voltage-level translation and signal inversion within compact mobile device power domains.

For engineers reviewing the 74AUP1G02FW5-7 datasheet, 74AUP1G02FW5-7 pinout, 74AUP1G02FW5-7 application, or 74AUP1G02FW5-7 equivalent, key selection criteria include supply voltage flexibility (0.8V–3.6V), ultra-low ICC (<0.9µA), IOFF-enabled system-level power sequencing, Schmitt-trigger noise immunity, and DFN1010-6 footprint compatibility with high-density PCB layouts.

Technical Context

This NOR gate implements standard Boolean logic Y = A + B using push-pull CMOS output stages. Its IOFF circuit actively disables outputs during power-down to prevent backflow current when VCC = 0V, enabling safe hot-insertion and multi-rail sequencing in mixed-voltage systems.

The integrated Schmitt-trigger inputs provide defined switching thresholds (VIH ≈ 0.8×VCC, VIL ≈ 0.3×VCC) and 250mV hysteresis at 3.0V, allowing robust operation with slow-rising or noisy control signals-critical in low-power microcontroller I/O expansion and reset conditioning circuits.

FAQ

What is the maximum recommended load capacitance for reliable 74AUP1G02FW5-7 operation?

The device is characterized up to 30pF load capacitance. At 3.3V VCC and CL = 30pF, propagation delay remains ≤8.5ns across –40°C to +125°C. For designs exceeding 30pF, derate output drive strength and verify timing margins using the CL-dependent tpd curves in DS35146 Rev. 6-2, page 6.

Can Pin 6 (NC) be grounded or tied to VCC?

No. Pin 6 is internally unconnected and must remain floating. Connecting it to any voltage violates the absolute maximum ratings and may cause unpredictable behavior or increased leakage. The datasheet explicitly prohibits biasing NC pins, and Diodes Incorporated's package drawings confirm no internal bond wire to this terminal.

Does the IOFF feature activate automatically when VCC drops below a threshold?

Yes. IOFF engages when VCC falls below approximately 0.2V, disabling the output MOSFETs regardless of input states. This occurs passively-no enable/disable control signal is needed. Measured IOFF leakage stays below ±3.5µA over full temperature range, ensuring safe isolation during brownout or controlled shutdown sequences.

How does the Schmitt-trigger input affect timing analysis in synchronous designs?

Schmitt-trigger inputs do not alter propagation delay specifications-the tpd values in DS35146 (pages 5–6) already account for internal hysteresis. However, they eliminate setup/hold uncertainty caused by slow or noisy edges, simplifying timing closure for asynchronous control signals like resets, interrupts, or manual switches where edge rate is uncontrolled.
