Diodes Incorporated 74LVC2G08HK3-7

Overview

74LVC2G08HK3-7 from Diodes Incorporated is a dual 2-input AND gate logic IC in X2-DFN1410-8 package, operating from 1.65V to 5.5V supply, delivering ±24mA output drive at 3.3V, with IOFF-enabled partial power-down protection and Schmitt-trigger inputs (100mV typical hysteresis at 3.0V). It enables voltage-level shifting and signal isolation in space-constrained portable electronics.

For engineers reviewing the 74LVC2G08HK3-7 datasheet, 74LVC2G08HK3-7 pinout, 74LVC2G08HK3-7 application, or 74LVC2G08HK3-7 equivalent, this device is selected for low-voltage logic interfacing, power-gated subsystem isolation, and noise-immune input conditioning in battery-powered embedded systems.

Technical Context

This CMOS dual AND gate implements two independent positive-logic functions (Y = A · B) with push-pull outputs. Its IOFF circuitry actively disables outputs during VCC = 0V, blocking back-current flow from live buses into unpowered sections-critical for hot-swap and multi-rail system design.

All inputs feature Schmitt-trigger action with ~100mV hysteresis at VCC = 3.0V, enabling robust operation with slow-rising signals (e.g., RC-filtered reset lines or mechanical switch inputs), while maintaining full 5.5V-tolerant input capability across the 1.65–5.5V supply range.

FAQ

Can 74LVC2G08HK3-7 operate with VCC = 1.65V while accepting 3.3V inputs?

Yes. The device is fully specified for 1.65V to 5.5V VCC operation and all inputs tolerate up to 5.5V regardless of supply voltage. At VCC = 1.65V, VIH is guaranteed ≥0.65×VCC (≥1.07V), so a 3.3V input exceeds this threshold and registers as logic HIGH with margin.

What happens to outputs during power-down when VCC = 0V?

When VCC drops near 0V, the IOFF circuit activates and forces both outputs (1Y and 2Y) into high-impedance state with leakage ≤±10μA (max at +125°C). This prevents current backflow from externally powered buses (e.g., 3.3V I²C lines) into the unpowered IC, protecting system integrity.

Is the X2-DFN1410-8 package compatible with standard reflow profiles?

Yes. The X2-DFN1410-8 package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 and withstands peak reflow temperatures up to 260°C. Its 0.4mm pitch and 0.35mm height are compatible with standard Type III stencil apertures and 0402-class placement accuracy.

Does the Schmitt-trigger input affect propagation delay?

No. Propagation delay (tpd) values in the datasheet (e.g., 2.1ns typical at 3.3V) are measured under standard conditions with clean, fast-rising inputs. Schmitt-trigger hysteresis improves noise immunity but does not degrade speed-it adds no measurable delay penalty compared to non-hysteresis inputs in the same family.
