The 74HC32D from Nexperia is a quad 2-input OR gate in an SOIC-14 package. Inputs include clamp diodes that enable current-limiting resistors to interface with voltages in excess of VCC. With wide 2.0V to 6.0V supply, CMOS low power, balanced propagation delays, and high noise immunity, it complies with JEDEC standards and is specified from -40\u00b0C to +125\u00b0C.<\/p>\n

Ideal for general-purpose logic OR functions, signal combining, and address decoding.","working_principle":"The 74HC32D implements four independent 2-input OR gates. Each gate performs the Boolean function Y = A OR B, outputting HIGH when either or both inputs are HIGH. The CMOS implementation uses complementary N-channel and P-channel MOSFET pairs for each gate, achieving rail-to-rail output swings with minimal quiescent current. Input clamp diodes protect against voltages exceeding VCC or below GND, allowing safe interfacing with higher voltage signals through current-limiting resistors. The balanced CMOS output stage provides symmetrical source and sink drive capability (\u00b15.2 mA), making it suitable for driving CMOS inputs directly.","pin_description":"\n
