Product Summary
The CD54HC374F3A is a high-speed CMOS logic octal D-Type flip-flop, 3-State Positive-Edge Triggered and the capability to drive 15 LSTTL loads. The eight edge-triggered flip-flops enter data into their registers on the LOWto 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 CD54HC374F3A is identical in function and differ only in their pinout arrangements.
