SCHS183C February 1998 -Revised May 2004 High-Speed CMOS Logic Octal D-Type Flip-Flop,
3-State Positive-Edge Triggered Features Description Buffered Inputs 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 edge-triggered 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, the
outputs are in the high-impedance state. The 374 and 574 are
identical in function and differ only in their pinout arrangements. Common Three-State Output Enable Control Three-State Outputs Bus Line Driving Capability Typical Propagation Delay (Clock to Q) = 15ns at …
