Nexperia USA Inc. 74LVC2G08DC,125

Overview

74LVC2G08DC from Nexperia is a dual 2-input AND gate logic IC in VSSOP8 (SOT765-1) package, operating from 1.65 V to 5.5 V supply, featuring 5 V-tolerant outputs, Schmitt-trigger inputs for noise immunity, and IOFF partial power-down protection. It enables level translation between 3.3 V and 5 V domains in compact space-constrained digital interfaces.

For engineers reviewing the 74LVC2G08DC datasheet, 74LVC2G08DC pinout, 74LVC2G08DC application, or 74LVC2G08DC equivalent, this device serves as a low-power, high-noise-immunity combinational logic element for mixed-voltage signal conditioning, bus interfacing, and enable/control gating in industrial control, portable electronics, and embedded I/O expansion.

Technical Context

The 74LVC2G08DC implements two independent AND gates with Schmitt-trigger inputs that accept slow-rising/falling signals up to 20 ns/V (at VCC = 1.65–2.7 V) and 10 ns/V (at VCC = 2.7–5.5 V), ensuring reliable switching in noisy environments. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down sequences.

It complies with JEDEC standards JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), and JESD8-B/JESD36 (2.7–3.6 V), and supports operation across –40 °C to +125 °C ambient temperature. Input voltage tolerance extends to 5.5 V regardless of VCC, enabling robust interfacing with legacy 5 V TTL and CMOS logic.

FAQ

Can the 74LVC2G08DC be used to interface 5 V microcontroller GPIOs with a 1.8 V FPGA?

Yes. Its 5 V-tolerant inputs accept 5 V logic highs while operating at VCC = 1.8 V, and its outputs swing rail-to-rail within the 1.8 V domain. This enables safe bidirectional voltage translation without external components, provided output loading remains within ±24 mA limits at 1.8 V.

Does the IOFF feature require external pull-up or pull-down resistors on outputs during power-down?

No. When VCC = 0 V, the IOFF circuitry forces outputs into high-impedance state with leakage ≤±2 μA - no external resistors are needed to prevent backfeed. However, if downstream inputs float, system-level pull resistors may still be required for defined logic states.

What is the maximum capacitive load the 74LVC2G08DC can drive while maintaining specified propagation delay?

At VCC = 3.3 V, the datasheet specifies tpd test conditions with CL = 50 pF. Driving loads >50 pF increases delay nonlinearly; for guaranteed 5.9 ns max delay (–40 °C to +125 °C), keep total load ≤50 pF including trace and input capacitance. Larger loads require derating or buffer insertion.

How does the Schmitt-trigger input improve reliability in noisy industrial environments?

Schmitt-trigger inputs provide ~150 mV hysteresis between rising and falling thresholds, rejecting noise spikes <150 mV and tolerating slow edge rates up to 20 ns/V. This prevents false triggering on EMI-coupled transients in motor drives, relay switching, or unshielded cable runs.
