Due to the large output drive capability and the 3-STATE feature, these devices are ide- Compatible with bus-oriented systems ally suited for interfacing with bus lines in a bus organized Output drive capability: 15 LS-TTL loads system. These devices are positive edge triggered flip-flops. Data at the D inputs, meeting the setup and hold time require- ments, are transferred to the Q outputs on positive going transitions of the CLOCK (CK) input. When a high logic level is applied to the OUTPUT CONTROL (OC) 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 74HC logic family is speed, function, and pinout com- patible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to V and ground.

Thus the 4.5V values should be used when OH OL designing with this supply. Worst case V and V occur at V 5.5V and 4.5V respectively. (The V value at 5.5V is 3.85V.) The worst case leakage cur- IH IL CC IH rent (I , I , and I ) occur for CMOS at the higher voltage and so the 6.0V values should be used. IN CC OZ www.fairchildsemi.com 2 MM74HC374
