A buffered Clock (CP) and Output Enable (OE) are common to all flipflops. The 74F534 is the same as the 74F374 except that the outputs are inverted. Features s Edge-triggered D-type inputs s Buffered positive edge-triggered clock s 3-STATE outputs for bus-oriented applications Ordering Code: Order Number 74F534SC 74F534SJ 74F534PC Package Number M20B M20D N20A Package Description 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300 Wide 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel.

The buffered clock and buffered Output Enable are common to all flip-flops. The eight flip-flops will store the state of their individual D inputs that meet the setup and hold times requirements on the LOW-to-HIGH clock (CP) transition. With the Output Enable (OE) LOW, the contents of the eight flip-flops are available at the outputs. When the OE is HIGH, the outputs go to the high impedance state. Operation of the OE input does not affect the state of the flip-flops.
