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 iin 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
VCC = 5V, CL = 15pF, TA = 25oC
• Fanout (Over Temperature Range)
- Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads
- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
