Hex Inverting Logic Level Down Converter •
Hex Logic Level Down Converter
General Description
The MM74HC4049 and the MM74HC4050 utilize
advanced silicon-gate CMOS technology, and have a mod-
ified input protection structure that enables these parts to
be used as logic level translators which will convert high
level logic to a low level logic while operating from the low
logic supply. For example, 0–15V CMOS logic can be con-
verted to 0–5V logic when using a 5V supply. The modified
input protection has no diode connected to VCC, thus allow-
ing the input voltage to exceed the supply. The lower zener
diode protects the input from both positive and negative
static voltages. In addition each part can be used as a sim-
ple buffer or inverter without level translation. The
MM74HC4049 is pin and functionally compatible to the
CD4049BC and the MM74HC4050 is compatible to the
CD4050BC
