Diodes Incorporated 74LVC2G32RA3-7

Overview

74LVC2G32RA3-7 from Diodes Incorporated is a dual 2-input OR gate logic IC in X2-DFN1210-8 package, operating from 1.65V to 5.5V supply, delivering ±24mA output drive at 3.3V with IOFF-enabled partial power-down isolation. It performs Boolean Y = A + B on two independent gates and is used for voltage-level shifting and signal isolation in portable computing peripherals.

For engineers reviewing the 74LVC2G32RA3-7 datasheet, 74LVC2G32RA3-7 pinout, 74LVC2G32RA3-7 application, or 74LVC2G32RA3-7 equivalent, key selection criteria include its 0.3 mm pitch DFN footprint, Schmitt-trigger input hysteresis (100 mV typ. at 3.0V), IOFF leakage <±10 µA, and guaranteed operation down to –40°C with tpd ≤5.3 ns at 3.3V.

Technical Context

This device implements two independent CMOS-based OR gates with push-pull outputs and Schmitt-trigger inputs-enabling robust noise immunity for slow-rising signals. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0V while inputs remain biased up to 5.5V.

All inputs tolerate 5.5V regardless of VCC level, supporting mixed-voltage interfacing. The logic function conforms strictly to positive-logic OR behavior (Y = A + B), with propagation delay tightly specified across –40°C to +125°C and supply voltages from 1.65V to 5.5V.

FAQ

Can 74LVC2G32RA3-7 operate with VCC = 1.65V while accepting 3.3V inputs?

Yes. Inputs are 5.5V-tolerant across the full 1.65V–5.5V VCC range. At VCC = 1.65V, VIH is guaranteed ≥1.07V and VIL ≤0.58V, ensuring reliable recognition of 3.3V logic highs and lows without level translation.

What is the thermal performance of the X2-DFN1210-8 package?

The X2-DFN1210-8 package has θJA = 395°C/W (FR-4, 2 oz copper, minimum pad layout). With max ICC = 40 µA and worst-case IOL = 24 mA at 3.3V, power dissipation stays below 80 mW-resulting in <32°C junction rise above ambient under typical conditions.

Does IOFF protect against back-current when only one supply rail is powered?

Yes. IOFF activates whenever VCC ≤0.2V, forcing outputs into high-impedance state regardless of input voltage (up to 5.5V). This prevents current flow from powered downstream logic into unpowered 74LVC2G32RA3-7, satisfying IEC 61000-4-2 system-level robustness requirements.

How does Schmitt-trigger action improve noise immunity compared to standard CMOS inputs?

Schmitt-trigger inputs provide 100 mV typical hysteresis at VCC = 3.0V-meaning the rising threshold (VIH) is ~100 mV higher than the falling threshold (VIL). This prevents oscillation on slowly changing or noisy signals, eliminating false triggers that would occur with standard CMOS inputs having near-zero hysteresis.
