NXP Semiconductors 74LV08D,112

Overview

74LV08D,112 from Nexperia is a quad 2-input CMOS AND gate operating from 1.0 V to 5.5 V supply, featuring TTL-level input compatibility at VCC = 2.7–3.6 V, −40 °C to +125 °C temperature rating, and SO14 (SOT108-1) package with 14 leads. It serves as a low-voltage logic combiner in digital control signal routing, bus gating, and enable logic for power management subsystems.

For engineers reviewing the 74LV08D,112 datasheet, 74LV08D,112 pinout, 74LV08D,112 application, or 74LV08D,112 equivalent, key selection criteria include supply voltage flexibility (1.0–5.5 V), guaranteed operation down to 1.0 V, output drive capability (±12 mA), propagation delay (7 ns typical at 3.3 V/15 pF), and industrial-grade thermal range (−40 °C to +125 °C).

Technical Context

The 74LV08D implements four independent 2-input AND gates in a single monolithic CMOS structure with input clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Its logic function conforms strictly to Boolean AND truth table with H/L/X-level interpretation per IEC 60617.

Designed for mixed-voltage system integration, it supports dual-rail interoperability: accepts TTL input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) at VCC = 2.7–3.6 V while maintaining full CMOS noise margins across 1.0–5.5 V operation. Output stage delivers rail-to-rail swing with VOH ≥ 2.82 V (IO = −6 mA, VCC = 3.0 V) and VOL ≤ 0.40 V (IO = 6 mA, VCC = 3.0 V).

FAQ

Can 74LV08D,112 operate reliably at 1.2 V supply?

Yes - the device is fully specified and guaranteed to function at VCC = 1.2 V, with VIH = 0.9 V and VIL = 0.3 V, and propagation delay of 45 ns (typical). Static and dynamic characteristics are validated across −40 °C to +125 °C at this voltage, meeting JEDEC JESD8-7 compliance.

Does 74LV08D,112 require external pull-up or pull-down resistors on unused inputs?

No - unused inputs may be tied directly to VCC or GND. The internal input structure includes clamp diodes and high-impedance CMOS gates; floating inputs are not permitted due to potential oscillation and increased ICC, but no external resistors are needed when properly terminated.

What is the maximum capacitive load the outputs can drive without exceeding timing specifications?

The datasheet specifies tpd test condition at CL = 15 pF. While outputs can physically drive >50 pF, propagation delay increases linearly with load capacitance - e.g., at CL = 50 pF and VCC = 3.3 V, tpd degrades to ~12 ns. For timing-critical paths, keep CL ≤ 15 pF or recalculate setup/hold margins accordingly.

Is 74LV08D,112 pin-compatible with older 74HC08 or 74LS08 packages?

Yes - the SO14 (SOT108-1) footprint matches standard 14-pin SOIC layouts used by 74HC08 and 74LS08. However, electrical behavior differs: 74LV08D operates down to 1.0 V and accepts TTL inputs only above 2.7 V, unlike LS/HC which require 5 V or have fixed thresholds. Direct replacement requires voltage domain verification.
