SCHS183E – NOVEMBER 1998 – REVISED OCTOBER 2022
CDx4HC374 High-Speed CMOS Logic Octal D-Type Flip-Flop, 3-State Positive-Edge Triggered
1 Features
• 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 • H
