Nexperia USA Inc. 74ALVC08D,118

Overview

74ALVC08D,118 from Nexperia is a quad 2-input CMOS AND gate with Schmitt-trigger inputs, IOFF partial power-down protection, 1.65 V to 3.6 V supply range, and operation up to +125 °C in SO14 (SOT108-1) package. It enables robust logic-level translation and noise-immune signal gating in mixed-voltage digital control systems.

For engineers reviewing the 74ALVC08D,118 datasheet, 74ALVC08D,118 pinout, 74ALVC08D,118 application, or 74ALVC08D,118 equivalent, this device supports high-noise-margin interfacing between 1.8 V/2.5 V/3.3 V domains, IOFF-enabled hot-swap subsystems, and industrial control logic where input rise/fall time tolerance and latch-up immunity are critical.

Technical Context

The 74ALVC08D implements four independent AND gates with Schmitt-trigger inputs-each providing hysteresis (typically 0.3 V at VCC = 3.3 V) to reject slow or noisy transitions. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current up to ±50 mA per pin.

It complies with JEDEC standards JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), and JESD8C/JESD36 (2.7–3.6 V), and meets JESD78 Class II.A latch-up immunity (>250 mA). Propagation delay ranges from 1.0 ns (VCC = 2.7 V) to 2.9 ns (VCC = 3.6 V) across temperature.

Key Specifications

Pinout & Package

FAQ

Does 74ALVC08D,118 support true bidirectional signal routing?

No. The 74ALVC08D,118 is a unidirectional AND gate with defined inputs (A/B) and outputs (Y). It lacks bus-hold, direction control, or tri-state capability. Its IOFF feature only disables outputs during power-down - it does not enable reverse signal flow or bus arbitration.

Can 74ALVC08D,118 be used with 5 V TTL outputs?

Yes - its inputs tolerate up to 3.6 V regardless of VCC, and it directly interfaces with TTL logic levels. However, when VCC ≤ 3.3 V, the output VOH will not reach 5 V, so downstream 5 V TTL inputs must recognize 3.3 V as HIGH (standard for TTL-compatible 3.3 V logic).

What is the maximum capacitive load the outputs can drive reliably?

Each output is characterized to drive up to 50 pF with guaranteed timing (tpd ≤ 3.3 ns at VCC = 3.6 V). For loads >50 pF, propagation delay increases linearly; derating is required beyond 300 pF to maintain setup/hold margins in synchronous systems.

Is thermal pad soldering required for the SO14 (SOT108-1) package?

No. The SO14 package has no exposed thermal pad. Unlike QFN variants (e.g., DHVQFN14), the SOT108-1 uses standard gull-wing leads; thermal performance relies on PCB copper area connected to pins 7 (GND) and 14 (VCC), not an underside pad.
