MC74LCX74 D

MC74LCX74
Low-Voltage CMOS Dual
D-Type Flip-Flop
With 5 V−Tolerant Inputs
The MC74LCX74 is a high performance, dual D−type flip−flop
with asynchronous clear and set inputs and complementary (O, O)
outputs. It operates from a 2.3 to 3.6 V supply. High impedance TTL
compatible inputs significantly reduce current loading to input drivers
while TTL compatible outputs offer improved switching noise
performance. A VI specification of 5.5 V allows MC74LCX74 inputs
to be safely driven from 5.0 V devices.
The MC74LCX74 consists of 2 edge−triggered flip−flops with
individual D−type inputs. The flip−flop will store the state of
individual D inputs, that meet the setup and hold time requirements, on
the LOW−to−HIGH Clock (CP) transition.
Designed for 2.3 V to 3.6 V VCC Operation
5.0 V Tolerant Inputs − Interface Capability With 5.0 V TTL Logic
LVTTL Compatible
LVCMOS Compatible
24 mA Balanced Output Sink and Source Capability
Near Zero Static Supply Current in All Three Logic States (10 mA)
Substantially Reduces System Power Requirements
Latchup Performance Exceeds 500 mA

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
