مقدمة المنتج:74HC08D,653 مقدمة المنتج

The 74HC08D,653 from Nexperia is a quad 2-input AND gate implemented in high-speed Si-gate CMOS technology. The device provides four independent 2-input AND gates in a single 14-pin SOIC package. The 74HC family offers wide supply voltage operation from 2.0 V to 6.0 V with CMOS input levels and low power consumption. The 7 ns typical propagation delay at 4.5 V enables use in medium-speed logic applications. Input clamp diodes allow interfacing to voltages exceeding VCC using current-limiting resistors. The device complies with JEDEC standards JESD7A and JESD8C.

مبدأ العمل:74HC08D,653 مبدأ العمل

The 74HC08D implements the Boolean AND function: the output Y is HIGH only when both inputs A and B are HIGH. Each of the four gates operates independently. The CMOS implementation uses complementary P-channel and N-channel MOSFETs in a push-pull output configuration, providing rail-to-rail output swing with low static power consumption. When both inputs are HIGH, the P-channel pull-up transistors are off and the N-channel pull-down network creates a conduction path, but the AND logic structure ensures the output is driven HIGH through the pull-up path. When any input is LOW, the corresponding N-channel transistor turns off and the output is pulled LOW through the N-channel network. The input clamp diodes protect against electrostatic discharge and allow interfacing beyond VCC with series resistance.
