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.
