Nexperia USA Inc. 74LVC08ADB,118

Overview

74LVC08ADB,118 from Nexperia is a quad 2-input AND gate in SSOP14 (SOT337-1) package, operating from 1.2 V to 3.6 V supply, with overvoltage-tolerant inputs up to 5.5 V and Schmitt-trigger inputs for noise immunity. It enables level translation between 3.3 V and 5 V logic domains in mixed-voltage digital control systems such as industrial I/O modules and programmable logic interfaces.

For engineers reviewing the 74LVC08ADB,118 datasheet, 74LVC08ADB,118 pinout, 74LVC08ADB,118 application, or 74LVC08ADB,118 equivalent, key selection criteria include input voltage tolerance, propagation delay at 3.3 V (typ. 2.3 ns), output drive strength (±24 mA), temperature range (–40 °C to +125 °C), and compatibility with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36.

Technical Context

This device implements four independent CMOS AND gates with Schmitt-trigger inputs, enabling robust operation with slow-rising or noisy signals. Each gate performs standard Boolean AND logic: output HIGH only when both inputs are HIGH; otherwise LOW.

It supports mixed-voltage interfacing via 5.5 V-tolerant inputs while powered from as low as 1.2 V, eliminating external level shifters. The design complies with JEDEC standards across three voltage bands (1.65–1.95 V, 2.3–2.7 V, 2.7–3.6 V) and guarantees operation from –40 °C to +125 °C.

FAQ

Is 74LVC08ADB,118 pin-compatible with standard 74LS08 in SSOP14?

Yes - it uses the same SOT337-1 (SSOP14) footprint and pinout as legacy 74LS08 devices. All 14 pins map identically: inputs (1A–4A, 1B–4B), outputs (1Y–4Y), GND (Pin 7), and VCC (Pin 14). No PCB redesign is needed for drop-in replacement.

Can 74LVC08ADB,118 safely interface a 5 V microcontroller output to a 1.8 V FPGA input?

No - while its inputs tolerate 5.5 V, its outputs swing from GND to VCC (1.2–3.6 V). To drive a 1.8 V FPGA input, VCC must be set to 1.8 V, limiting output HIGH to ~1.6 V (VCC − 0.2 V), which may fall below the FPGA's VIH threshold. Use a dedicated level shifter for bidirectional 5 V ↔ 1.8 V translation.

What is the maximum capacitive load this device can drive at 10 MHz with 3.3 V supply?

At 3.3 V and 10 MHz, with CPD = 10.5 pF and typical output load CL = 30 pF (per Table 8), dynamic power is ~1.1 mW per gate. The device reliably drives up to 50 pF total load (including trace and input capacitance) while maintaining <5 ns propagation delay and monotonic edges, per test conditions in Figure 5.

Does 74LVC08ADB,118 require external pull-up or pull-down resistors on unused inputs?

No - unused inputs may be tied directly to VCC or GND. Due to Schmitt-trigger inputs and CMOS structure, floating inputs are prohibited and will cause increased ICC and potential oscillation. For unused gates, connect both inputs to GND (to force LOW output) or one input to VCC and the other to GND (to force LOW output and minimize shoot-through current).
