MC74HC4050N Datasheet PDF - Motorola

●Hex Buffers/Logic-Level Down Converters

●High–Performance Silicon–Gate CMOS

●The MC54/74HC4049 consists ofsix inverting buffers, and the MC54/74HC4050 consists of six noninverting buffers. They are identical in pinout to the MC14049UB and MC14050B metal–gate CMOS buffers. The device inputs are compatible with standard CMOS outputs; with pullup

●resistors, they are compatible with LSTTL outputs.

●The input protection circuitry on these devices has been modified by eliminating the VCC diodes to allow the use of input voltages up to 15 volts. Thus,the devices may be used as logic–level translators that convert from a high voltage to a low voltage while operating at the low–voltage power supply.They allow MC14000–series CMOS operating up to 15 volts tobe interfacedwith High–Speed CMOS at 2 to 6 volts. The protection diodes to GND are Zener diodes, which protect the inputs from both positive and negative voltage transients.
