Input logic thresholds scale with VCC, so 5V CMOS and TTL outputs will reliably drive the gate at a 5V supply."},{"question":"What is the pinout of SN74HC21DR?","answer":"The SN74HC21DR uses the standard 14-SOIC pinout for a dual 4-input AND gate. Pin assignments follow the 74HC21 convention: pins 1-4 and 9-12 are the two sets of four inputs, pin 6 and 8 are the outputs, pin 7 is GND, and pin 14 is VCC."},{"question":"Is SN74HC21DR equivalent to 74HC21?","answer":"Yes, the SN74HC21DR is the surface-mount variant of the 74HC21 logic function.
