Hex Logic Level Down Converter
General Description
The MM74HC4049 and the MM74HC4050 utilize
advanced silicon-gate CMOS technology, and have a modified input protection structu re 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 converted to 0–5V logic when usin g a 5V su pply. The modified
input protection has no diode connected to V
CC
, thus allow-
ing the input voltage to exceed the supply. The lower zener
diode protects the input fr om 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

Absolute Maximum Ratings(Note 1)

Recommended Operating
Conditions
Note 1: Absolute Maximum Ratings are those values beyond which dam-
age to the device may occur.
Note 2: Unless otherwise specified all voltages are referenced to ground.
Note 3: Power Dissipation temper ature dera ting — plas tic “N” packa ge: −
12 mW/°C from 65 °C to 85°C.
DC Electrical Characteristics (Note 4)
Note 4: For a power supply of 5V ±10% the wor st case output vo ltages (VOH and VOL) occur for HC a t 4.5 V. Thus the 4.5V values should be u sed wh en
designing with this supply. Worst case V
IH
and VIL occur at V
CC
= 5.5V and 4.5V res pectively. (The VIH value at 5.5V is 3.85V.) The worst case leakage c ur-
rent (I
IN
, ICC, IOZ) occur for CMOS at the higher voltage and so the 6. 0V values should be use d.
