What this quad AND gate does on your board
The SN74LVC08ADT is a Texas Instruments 74LVC-series quad 2-input AND gate in a 14-SOIC package. It packs four independent AND gates into one surface-mount IC, each gate taking two inputs and giving you one output — the logical AND of those two signals. The wide operating temperature range from -40°C to 125°C means it can sit in an industrial control board or an automotive module without worrying about the environment.
Key specs that decide the fit
The maximum quiescent current is just 1 µA — the chip barely draws power when the outputs are static. That 3.9 ns is the time from when the input crosses the threshold to when the output starts changing — in a 100 MHz clock path, that delay adds up, so budget it into your timing closure. The input logic thresholds are specified: low is 0.7 V to 0.8 V, high is 1.7 V to 2 V. At 3.3 V supply, a 1.8 V signal from a low-voltage microcontroller will still be recognised as a logic high, making this gate a natural level translator in mixed-voltage designs.
Active production and sourcing
It is RoHS3 compliant, so it meets the current EU restriction requirements for lead and other substances. The 14-SOIC package (0.154" wide, 3.90 mm body) is a common footprint that many PCB layout tools have as a standard library part.
