High Speed CMOS Logic Octal D-Type Flip-Flop,
Three-State Positive-Edge Triggered
Features
Description
• Buffered Inputs
The Harris CD74HC374, CD74HCT374, CD74HC574 and
CD74HCT574 are Octal D-Type Flip-Flops with Three-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 three-state outputs and is independent of
the register operation. When Output Enable (OE) is HIGH the
outputs will be 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
VCC = 5V, CL = 15pF, TA = 25oC
• Fanout (Over Temperature Range)
- Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads
- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
