Hex Buffers/Logic-Level

Down Converters

High–Performance Silicon–Gate CMOS

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.

eliminating the V CC 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 to be

interfaced with 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.
