The SN74LV08AD is a Texas Instruments quad 2-input AND gate from the 74LV series, packaged in a 14-SOIC (0.154", 3.90mm width) surface-mount package. It operates from 2V to 5.5V supply, making it a direct drop-in for 3.3V or 5V logic rails without level shifting. With four independent AND gates, each driving 12mA output current, this part handles typical glue-logic tasks — address decoding, enable gating, or signal conditioning — in mixed-voltage boards where the 74HC family's 2V–6V range overlaps but the LV series offers lower quiescent current at 20 µA max.
The input logic levels — low at 0.5V, high at 1.5V — are CMOS-compatible, so it interfaces directly with most MCUs and FPGAs on the same rail. The 7.9ns propagation delay at 5V and 50pF load gives a 126 MHz toggle rate ceiling — adequate for most bus gating but not for high-speed clock trees.
Lifecycle and sourcing posture
The 14-SOIC package (3.90mm body width) is a common footprint shared with many 74-series logic ICs.
How it compares to 74HC08 and 74LS08
The 74LV08AD can replace a 74HC08 in most designs — both are CMOS, both run from 2V to 6V (LV is 2V–5.5V). The LV family draws lower quiescent current (20 µA vs ~80 µA for HC) and has slightly faster propagation delay at 5V. Against a 74LS08 (bipolar, 4.75V–5.25V only), the LV part is a direct pin-compatible swap but requires the supply to stay within 5.5V — LS08 can tolerate 7V transients. If your board runs at 3.3V, the 74LV08AD is a better fit than 74HC08 (which slows down at lower voltages) and far better than 74LS08 (which needs 5V). The pinout is identical across all three families — 14-pin SOIC with the same gate assignments.
