Bare Die Product Detail: 54AC74

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 54AC74, Motorola MC54AC74, RCA HARRIS 54AC74 and Texas Instruments SN54AC74, CD54AC74.
Features:
    ** PRODUCT DISCONTINUED **
    • Outputs Source/Sink 24 mA
    • Outputs directly interface to CMOS, NMOS, and TTL
    • Max input current 1µA over full Military Temperature Range
    • Asynchronous Set-Reset Capability
    • Operating Voltage Range: 2.0 to 6.0V
    • Direct drop-in replacement for obsolete components in long term programs
Vendor:
SiS OBSOLETE
