The device provides four independent AND gates in a single SO14 package. It operates over a supply voltage range of 2.0 V to 6.0 V and features CMOS low power dissipation combined with high noise immunity. The inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC. The device is fully specified from -40\u00b0C to +125\u00b0C and complies with JEDEC standards JESD8C and JESD7A. ESD protection exceeds 2000V HBM and 1000V CDM, making it suitable for demanding industrial and automotive applications.","working_principle":"The 74HC08D contains four independent 2-input AND gates. Each gate performs the Boolean function Y = A AND B. The output is HIGH only when both inputs A and B are HIGH; otherwise, the output is LOW. The CMOS input stage ensures low static power consumption with high input impedance. The output buffer provides \u00b15.2 mA drive capability, sufficient for driving multiple CMOS or TTL loads. Input clamp diodes protect the internal circuitry from voltage transients and allow safe interfacing to higher voltage signals when used with appropriate current limiting resistors.","pin_description":"\n
