Diodes Incorporated 74AUP1G08FW4-7

Overview

74AUP1G08FW4-7 from Diodes Incorporated is a single 2-input positive AND 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 partial power-down protection, and includes Schmitt-trigger inputs with ~250mV hysteresis at VCC = 3.0V - enabling robust signal conditioning in low-voltage sensor interface and power management circuits.

For engineers reviewing the 74AUP1G08FW4-7 datasheet, 74AUP1G08FW4-7 pinout, 74AUP1G08FW4-7 application, or 74AUP1G08FW4-7 equivalent, key selection criteria include its ultra-low ICC (<0.9µA), wide VCC range, IOFF-enabled system-level power sequencing, and DFN1010-6 package compatibility with space-constrained PCB layouts.

Technical Context

This device implements a standard Boolean AND function (Y = A • B) using ultra-low-power CMOS process technology optimized for sub-1V operation. Its Schmitt-trigger inputs tolerate slow-rising/falling signals (≤200 ns/V transition rate), while the IOFF circuit actively disables outputs during partial power-down to prevent backflow current between powered and unpowered domains.

The X2-DFN1010-6 package (1.0mm × 1.0mm × 0.4mm, 0.35mm pad pitch) supports high-density routing and thermal performance with θJA = 445°C/W. Propagation delay ranges from 1.0ns (typ, 3.3V, CL=5pF) to 6.5ns (max, 1.2V, CL=30pF), ensuring timing predictability across voltage and load conditions.

FAQ

What is the maximum operating temperature for the 74AUP1G08FW4-7?

The 74AUP1G08FW4-7 is rated for continuous operation from –40°C to +125°C ambient temperature, with junction temperature up to +150°C. Its thermal resistance (θJA = 445°C/W) and low power dissipation ensure reliable performance in sealed enclosures or thermally constrained wearables without active cooling.

Does the 74AUP1G08FW4-7 require external pull-up or pull-down resistors on inputs?

No - unused inputs must be tied to VCC or GND per datasheet recommendation (Note 8), but no external resistors are needed due to the device's internal input structure. The Schmitt-trigger inputs have defined thresholds and do not float; leaving them unconnected risks undefined logic states and increased ICC.

Can the 74AUP1G08FW4-7 drive a 50pF load reliably?

Yes - while characterized up to 30pF in the datasheet, the ±4mA drive strength at 3.0V supports 50pF loads with predictable delay (estimated ≤8ns at 3.3V). For precise timing, verify with actual board parasitics and consider adding series termination if ringing occurs on long traces.

Is the NC pin on the X2-DFN1010-6 package electrically isolated?

Yes - Pin 3 (NC) is internally unconnected and electrically isolated from all other terminals. It must remain unconnected on the PCB; soldering or routing to this pad provides no functional benefit and may risk shorting adjacent terminals due to the 0.35mm pad pitch.
