The 74HC4050D from Nexperia is a hex non-inverting buffer with over-voltage tolerant inputs in an SOIC-16 (9.9×3.9mm) package. The inputs can tolerate voltages up to 15V regardless of the supply voltage, making it ideal for HIGH-to-LOW level shifting applications. The device operates from 2.0V to 6.0V with \u00b15.2mA output drive at 6V.<\/p>\n

This feature makes it particularly useful for converting high-voltage logic levels to lower-voltage levels, such as 5V CMOS to 3.3V CMOS, or 12V logic to 5V. Unlike standard CMOS inputs that have clamp diodes to VCC, the 74HC4050 inputs are designed without VCC-side clamp diodes, allowing input voltages to exceed VCC without damage or current injection into the supply rail.","working_principle":"Each of the six buffer channels consists of a two-stage inverter chain that provides non-inverting logic function. The input stage uses a modified protection structure that omits the VCC-side ESD clamp diode, allowing input voltages to rise above VCC without forward-biasing a diode into the supply rail. The input signal is sensed relative to GND only, and the output stage drives the output to VCC (logic high) or GND (logic low) based on the input threshold. The output voltage is always referenced to VCC and GND, effectively translating the high-voltage input down to the supply rail level.","pin_description":"
