Nexperia USA Inc. 74LVC08ABQ,115

Overview

74LVC08ABQ,115 from Nexperia is a quad 2-input AND gate in DHVQFN14 (SOT762-1) 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 systems such as industrial I/O controllers and FPGA interface buffers.

For engineers reviewing the 74LVC08ABQ,115 datasheet, 74LVC08ABQ,115 pinout, 74LVC08ABQ,115 application, or 74LVC08ABQ,115 equivalent, key selection criteria include input voltage tolerance, propagation delay at 3.3 V (typ. 2.3 ns), thermal-enhanced QFN packaging, and guaranteed operation from –40 °C to +125 °C.

Technical Context

This device implements four independent CMOS AND gates with Schmitt-trigger inputs, enabling robust signal conditioning in noisy environments. Each gate accepts inputs referenced to GND and tolerates up to 5.5 V regardless of VCC, supporting bidirectional level shifting without external components.

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 features ESD protection exceeding 2000 V HBM and 1000 V CDM - critical for board-level reliability in automated assembly and field-deployed equipment.

FAQ

Can 74LVC08ABQ,115 operate with a 1.2 V supply and still accept 5 V inputs?

Yes. The device is explicitly rated for overvoltage-tolerant inputs up to 5.5 V across its full supply range (1.2 V to 3.6 V). Input clamping circuitry prevents damage and ensures correct logic interpretation even when VCC = 1.2 V and VI = 5 V, enabling true level translation without external components.

Is the exposed thermal pad on the DHVQFN14 package required to be soldered to ground?

No. Per Nexperia's datasheet (SOT762-1, section 5.2), the exposed pad (labeled GND(1)) has no electrical or mechanical requirement to be soldered. If connected, it must remain floating or tied to GND - but thermal performance gains are marginal unless thermally anchored with ≥4 vias to inner ground planes.

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

The absolute maximum output current is ±24 mA per output pin at VCC = 3.0 V. At VCC = 1.65 V, the guaranteed drive is ±4 mA; at VCC = 2.3 V, it is ±8 mA; and at VCC = 2.7 V, it is ±12 mA. These values are specified in Table 6 (Static Characteristics) and define safe fan-out capability under worst-case voltage and temperature conditions.

Does the Schmitt-trigger input affect propagation delay compared to standard CMOS inputs?

Yes - Schmitt-trigger inputs add ~0.5 ns to typical propagation delay versus non-hysteresis equivalents, but this is offset by improved noise rejection. At VCC = 3.3 V, tpd remains 2.3 ns (typ), and input hysteresis (≥0.3 V) ensures reliable switching even with rise/fall times up to 10 ns/V - critical for long-trace or unshielded industrial wiring.
