They possess the low power consumption of stan- dard 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 ’HC534, ’HCT534, ’HC564, and ’HCT564 are positive edge triggered flip-flops. Data at the D inputs, meeting the setup and hold time requirements, are inverted and trans- ferred to the Q outputs on the positive going transition of the CLOCK input. When a high logic level is applied to the OUT- PUT 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 HCT logic family is speed, function, and pin compatible with the standard LS logic family. Ordering Information PART NUMBER TEMP.
