Nexperia USA Inc. 74LVC2G08GXX

Overview

74LVC2G08 from Nexperia is a dual 2-input AND gate logic IC designed for level translation between 3.3 V and 5 V systems, featuring Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and operation across 1.65 V to 5.5 V supply. It delivers ±24 mA output drive at 3.0 V and supports industrial temperature range (–40 °C to +125 °C) in multiple ultra-compact packages including XSON8 and TSSOP8.

For engineers reviewing the 74LVC2G08 datasheet, 74LVC2G08 pinout, 74LVC2G08 application, or 74LVC2G08 equivalent, this device is selected for mixed-voltage signal gating, bus isolation, and power-aware logic interfacing where input tolerance, low static current (<4 μA), and sub-5 ns propagation delay at 5 V are critical design requirements.

Technical Context

The 74LVC2G08 implements two independent AND gates with rail-to-rail input voltage tolerance up to 5.5 V and 5 V–compatible outputs, enabling seamless interfacing between legacy 5 V TTL and modern 1.65–3.3 V CMOS domains. Its IOFF circuit actively disables outputs during power-down to prevent backflow current, satisfying JEDEC JESD8-7/5/B compliance across supply ranges.

Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at 3.3 V), allowing robust operation with slow-rising signals, while dynamic characteristics include 1.7 ns typical propagation delay (VCC = 5 V) and 14.4 pF power dissipation capacitance per gate-key for estimating dynamic power in high-frequency enable/control paths.

Key Specifications

Pinout & Package

Available in six surface-mount packages: TSSOP8 (SOT505-2), VSSOP8 (SOT765-1), and four XSON8 variants (SOT833-1, SOT1116, SOT1203, SOT1233-2), all 8-terminal, leadless or gull-wing, with body heights down to 0.32 mm for space-constrained PCBs.

FAQ

What is the maximum input voltage the 74LVC2G08 can tolerate?

The 74LVC2G08 accepts input voltages up to 5.5 V regardless of VCC level, enabling direct connection to 5 V sources even when powered from 1.65 V or 3.3 V. This overvoltage tolerance is specified in Table 5 (Limiting Values) and confirmed across all package variants in the Rev. 20 datasheet.

Does the 74LVC2G08 support partial power-down mode?

Yes-the device integrates IOFF circuitry that places outputs in high-impedance state when VCC = 0 V, preventing damaging backflow current during hot-swap or system sleep states. This feature is validated per JEDEC JESD78 and documented in Section 1 (General description) and Table 7 (Static characteristics).

Which package options offer the smallest footprint and height?

The SOT1233-2 (X2SON8) package measures 1.35 × 0.8 × 0.32 mm-smallest body area and lowest profile among all variants. It also provides enhanced thermal performance (300 mW Ptot) versus standard XSON8 packages (250 mW), as detailed in Table 5 and Figure 11 of the datasheet.

Can the 74LVC2G08 replace older 74HC or 74HCT logic in existing designs?

Yes-pin-compatible with 74HC2G08 and 74HCT2G08 in TSSOP8 and VSSOP8 packages, but with improved features: wider VCC range (1.65–5.5 V vs. 2–6 V), guaranteed 5 V I/O tolerance, and IOFF support. Electrical behavior matches HC/HCT logic tables, enabling drop-in replacement where voltage and thermal specs align.
