Features, Applications

The is a high speed, low-power octal D-type flipflop featuring separate D-type inputs for each flip-flop and 3-STATE outputs for bus-oriented applications. 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.

The 74F534 consists of eight edge-triggered flip-flops with individual D-type inputs and 3-STATE complementary outputs. 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.
