Nexperia USA Inc. 74LVC08ADB,112

Overview

74LVC08ADB,112 from Nexperia is a quad 2-input AND gate logic IC operating from 1.2 V to 3.6 V supply, featuring overvoltage-tolerant inputs (up to 5.5 V), Schmitt-trigger inputs for noise immunity, and guaranteed operation from –40 °C to +125 °C. It enables level translation between 3.3 V and 5 V domains in mixed-voltage digital systems such as industrial I/O controllers and FPGA interface buffers.

For engineers reviewing the 74LVC08ADB,112 datasheet, 74LVC08ADB,112 pinout, 74LVC08ADB,112 application, or 74LVC08ADB,112 equivalent, this device supports high-speed logic interfacing with propagation delays as low as 1.0 ns at 3.3 V, input transition rate tolerance up to 20 ns/V, and robust ESD protection (HBM >2000 V, CDM >1000 V).

Technical Context

The 74LVC08ADB,112 implements four independent AND gates in a single monolithic CMOS structure, each with Schmitt-trigger inputs enabling reliable operation with slow-rising or noisy signals. Its input voltage range (0–5.5 V) exceeds VCC, allowing direct connection to 5 V TTL outputs while powered from 1.65–3.6 V supplies.

It complies with JEDEC standards JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V), and delivers rail-to-rail output swing with VOH ≥ VCC − 0.2 V (at −24 mA) and VOL ≤ 0.55 V (at 24 mA) across its full temperature range.

FAQ

Is 74LVC08ADB,112 pin-compatible with standard 74LVC08A variants?

Yes - it shares identical pinout (14-pin SSOP) and logic function with other 74LVC08A types. Pin assignments match JEDEC-standard SO14/TSSOP14 footprints: inputs (1A–4A, 1B–4B), outputs (1Y–4Y), GND (Pin 7), and VCC (Pin 14). No layout changes are needed when substituting within the same package family.

Can 74LVC08ADB,112 safely interface a 5 V microcontroller GPIO to a 1.8 V FPGA input?

Yes - its inputs tolerate up to 5.5 V regardless of VCC, and with VCC = 1.8 V, VIH is guaranteed ≥ 1.26 V (0.7 × VCC) and VOL ≤ 0.45 V (at 4 mA), satisfying 1.8 V LVTTL input thresholds. No external resistors or translators are required.

What is the maximum output current per pin, and how does it vary with supply voltage?

Each output drives ±24 mA at VCC = 3.0 V, with VOH ≥ 2.2 V and VOL ≤ 0.55 V. At lower VCC (e.g., 1.65 V), drive strength reduces to ±4 mA (VOH ≥ 1.2 V, VOL ≤ 0.45 V), scaling linearly with supply - verified per Table 6 in the datasheet across −40 °C to +125 °C.

Does 74LVC08ADB,112 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 design, floating inputs are not permitted; however, no external resistors are needed beyond direct connection, as input leakage is ≤ ±0.1 μA (typical) and VIH/VIL thresholds are well-defined across voltage and temperature.
