MC74HCT74A
Dual D FlipFlop with Set
and Reset with LSTTL
Compatible Inputs
HighPerformance SiliconGate CMOS
The MC74HCT74A is identical in pinout to the LS74. This device
may be used as a level converter for interfacing TTL or NMOS outputs
to High Speed CMOS inputs.
This device consists of two D flipflops with individual Set, Reset,
and Clock inputs. Information at a Dinput is transferred to the
corresponding Q output on the next positive going edge of the clock
input. Both Q and Q outputs are available from each flipflop. The Set
and Reset inputs are asynchronous.
Features
Output Drive Capability: 10 LSTTL Loads
TTL NMOS Compatible Input Levels
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 4.5 to 5.5 V
Low Input Current: 1.0 A
In Compliance With the JEDEC Standard No. 7.0 A Requirements
Chip Complexity: 136 FETs or 34 Equivalent Gates
PbFree Packages are Available*

*Both outputs will remain high as long as Set and
Reset are low, but the output states are unpredict-
able if Set and Reset go high simultaneously.
