High Speed CMOS Logic Octal Positive-Edge-Triggered D-Type Flip-Flops with 3-State Outputs

 

Description

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.
