The ’HC374, ’HCT374, ’HC574, and ’HCT574 are octal D-type flip-flops with 3-state outputs and the capability to drive 15 LSTTL loads. The eight edgetriggered flip-flops enter data into their registers on the LOW to HIGH transition of clock (CP). The output enable (OE) controls the 3-state outputs and is independent of the register operation. When OE is HIGH.
• Buffered inputs
• Common three-state output enable control
• Three-state outputs
• Bus line driving capability
• Typical propagation delay (clock to Q) = 15 ns at
VCC = 5 V, CL = 15 pF, TA = 25℃
• Fanout (over temperature range)
– Standard outputs: 10 LSTTL loads
– Bus driver outputs: 15 LSTTL loads
• Wide operating temperature range:
–55℃ to 125℃
• Balanced propagation delay and transition times
• Significant power reduction compared to LSTTL Logic ICs
• HC types
– 2-V to 6-V operation
– High noise immunity: NIL = 30%, NIH = 30% of
VCC at VCC = 5 V
• HCT types
– 4.5-V to 5.5-V Operation
– D.
