General DescriptionThe MM74HC4049 and the MM74HC4050 utilizeadvanced silicon-gate CMOS technology, and have a mod-ified input protection structure that enables these parts tobe used as logic level translators which will convert highlevel logic to a low level logic while operating from the lowlogic supply. For example, 0–15V CMOS logic can be con-verted to 0–5V logic when using a 5V supply. The modifiedinput protection has no diode connected to VCC, thus allow-ing the input voltage to exceed the supply. The lower zenerdiode protects the input from both positive and negativestatic voltages. In addition each part can be used as a sim-ple buffer or inverter without level translation. TheMM74HC4049 is pin and functionally compatible to theCD4049BC and the MM74HC4050 is compatible to theCD4050BCFeaturessTypical propagation delay: 8 nssWide power supply range: 2V–6VsLow quiescent supply current: 20 µA maximum (74HC)sFanout of 10 LS-TTL loads

Octal D-Type Latch • 3-STATE Octal D-Type Flip-Flop

General Description

The MM74HCT573 octal D-type latches and

MM74HCT574 octal D-type flip-flop advanced silicon-gate

CMOS technology, which provides the inherent benefits of

low power consumption and wide power supply range, but

are LS-TTL input and output characteristic and pin-out

compatible. The 3-STATE outputs are capable of driving 15

LS-TTL loads. All inputs are protected from damage due to

static discharge by internal diodes to VCC and ground.

When the MM74HCT573 Latch Enable input is HIGH, the

Q outputs will follow the D inputs. When the Latch Enable

goes LOW, data at the D inputs will be retained at the out-

MM74HC14

Hex Inverting Schmitt Trigger

General Description

The MM74HC14 utilizes advanced silicon-gate CMOS

technology to achieve the low power dissipation and high

noise immunity of standard CMOS, as well as the capability

to drive 10 LS-TTL loads.

The 74HC logic family is functionally and pinout compatible

with the standard 74LS logic family. All inputs are protected

from damage due to static discharge by internal diode

clamps to VCC and ground.Features
