Diodes Incorporated 74AHC1G00SE-7

Overview

74AHC1G00SE-7 from Diodes Incorporated is a single 2-input positive NAND gate in SOT353 package, operating from 2.0 V to 5.5 V supply, delivering ±8 mA output drive at 5.0 V, with Schmitt-trigger inputs for noise immunity, and RoHS-compliant lead-free finish. It performs the Boolean function Y = A·B and is used in logic-level translation and signal conditioning within compact consumer electronics.

For engineers reviewing the 74AHC1G00SE-7 datasheet, 74AHC1G00SE-7 pinout, 74AHC1G00SE-7 application, or 74AHC1G00SE-7 equivalent, key selection criteria include input hysteresis margin (≥0.4 V at VCC = 3.3 V), propagation delay ≤7.0 ns (CL = 15 pF, VCC = 5 V), output drive capability, and SOT353 thermal resistance (θJA = 430 °C/W).

Technical Context

This device implements a single 2-input NAND logic function with push-pull CMOS output stage and Schmitt-trigger inputs-enabling robust operation with slow-rising or noisy signals. Its input hysteresis improves noise immunity without external components, and its rail-to-rail output swing supports interfacing across mixed-voltage domains (2.0–5.5 V).

The 74AHC1G00SE-7 uses advanced AHC-series silicon optimized for low dynamic power (Cpd = 10 pF) and fast switching (tpd ≤ 3.5 ns typ. at VCC = 5 V, CL = 15 pF). It meets JESD22 ESD ratings: 2 kV HBM, 1 kV CDM, and 200 V MM, and complies with JESD78 Class II latch-up immunity (>100 mA).

FAQ

What is the minimum supply voltage for reliable operation of the 74AHC1G00SE-7?

The 74AHC1G00SE-7 is specified for reliable operation down to 2.0 V, with guaranteed VIH ≥1.5 V and VIL ≤0.5 V at that rail. Below 2.0 V, timing and output drive degrade unpredictably, and the device may fail to meet logic thresholds or propagate transitions correctly.

Can unused inputs be left floating?

No. Unused inputs must be tied to VCC or GND per datasheet Note 3. Floating inputs cause increased ICC, unpredictable output states, and potential oscillation due to internal node metastability-especially critical in CMOS devices with high input impedance and Schmitt-trigger hysteresis.

Is the 74AHC1G00SE-7 compatible with 1.8 V logic systems?

No. Its absolute minimum VCC is 2.0 V, and VIH at 2.0 V is specified as ≥1.5 V. A 1.8 V system's high-level output (typically ~1.6–1.7 V) falls below this threshold, risking misinterpretation as a logic low. Use SN74LVC1G00 or 74AUP1G00 for true 1.8 V compatibility.

Does the SOT353 package require special PCB layout considerations?

Yes. The SOT353's 0.65 mm lead pitch demands precise stencil aperture design and controlled reflow profile. Diodes' AP02001 recommends 0.35 mm pad width, 0.75 mm pad length, and 0.25 mm solder mask opening-deviations risk bridging or insufficient wetting. Thermal relief on GND/VCC pads is discouraged due to low θJC (155 °C/W).
