Each of 6 channels inverts the input and can convert from a higher input logic level to a lower VCC level since inputs tolerate voltages above VCC. At VCC=5V, outputs can directly drive 2 TTL loads. TSSOP-16 package for compact designs.","working_principle":"Each inverter channel uses a special input structure where the input protection network allows VIH to exceed VCC without latchup or damage. The output stage is a push-pull CMOS inverter powered from VCC. When input is high (can be > VCC), the output drives low with IOL up to 18mA. When input is low, the output drives high.","pin_description":"
