Three-State Inverting Positive-Edge Triggered
Description
The Harris CD74HC534, CD74HCT534, CD74HC564 and
CD74HCT564 are high speed Octal D-Type Flip-Flops manufactured with silicon gate CMOS technology. The y possess
the low power consumption of standard CMOS integrated circuits, as well as the ability to drive 15 LSTTL loads. Due to the
large output drive capability and the three-state feature, these
devices are ideally suited for interfacing with bus lines in a bus
organized system. The two types are functionally identical and
differ only in their pinout arrangements.
The CD74HC534, CD74HCT534, CD74HC564 and
CD74HCT564 are positive edge triggered flip-flops. Data at
the D inputs, meeting the setup and hold time requirements,
C to 125oC
OH
are inverted and transferred to the Q outputs on the positive
going transition of the CLOCK input. When a high logic level is
applied to the OUTPUT ENABLE input, all outputs go to a
high impedance state, regardless of what signals are present
at the other inputs and the state of the storage elements.
The CD74HCT logic family is speed, function, and pin
compatible with the standard 74LS logic family.
