Bare Die Product Detail: 54ACT74

D-Type Flip-Flop:
Dual D-type flip-flop made in 1.5µm 5V CMOS. Each flip-flop has separate data, set, reset, clock inputs & QQ\ outputs. D-Input level transfers to Q output on positive clock pulse. Set & Reset lines are clock independent, set via high levels.

The device directly replaces legacy National / Fairchild 54ACT74, Motorola MC54ACT74, RCA HARRIS 54ACT74 and Texas Instruments SN54ACT74, CD54ACT74.

Features:

Output Drive Capability: 10 LSTTL Loads
Inputs directly interface TTL
Outputs directly interface to CMOS, NMOS, and TTL
Max input current 1µA
Asynchronous Set-Reset Capability
Sinks/Sources 24mA
Operating Voltage Range: 4.5 to 5.5V
Full military temperature range
Lower power replacement for Bipolar LS or F series
Direct drop-in replacement for obsolete components in long term programs
