They exhibit the low power consumption of standard CMOS integrated circuits, together with the ability to drive 10 LSTTL loads. These flip-flops have independent J, K, Reset and Clock inputs and Q and Q outputs. They change state on the negative-going transition of the clock pulse. Reset is accomplished asynchronously by a low level input. This device is functionally identical to the HC/HCT107 but differs in terminal assignment and in some parametric limits. The 74HCT logic family is functionally as well as pin compatible with the standard 74LS logic family. Pinout CD74HC73, CD74HCT73 (PDIP, SOIC) TOP VIEW Ordering Information PART NUMBER TEMP.
