FEATURES
8-bit positive edge-triggered register
3-State inverting output buffers
Common 3-State Output register
Independent register and 3-State buffer operation
DESCRIPTION
The 74F534 is an 8-bit edge-triggered register coupled to eight
3-State output buffers. The two sections of the device are controlled
independently by the Clock (CP) and Output Enable (OE) control
gates.
The register is fully edge-triggered. The state of each D input, one
setup time before the Low-to-High clock transition is transferred to
the corresponding flip-flop’s Q output.
The 3-State output buffers are designed to drive heavily loaded
3-State buses, MOS memories, or MOS microprocessors. The
active Low Output Enable (OE) controls all eight 3-State buffers
independent of the latch operation. When OE is Low, the latched or
transparent data appears at the outputs. When OE is High, the
outputs are in high impedance “off” state, which means they will
neither drive nor load the bus.
