The Output LOW drive factor is 2. Temperature Ranges. When a circuit has reached able Counters. Similarly, the TCD output will master reset, individual preset, count up and count down go LOW when the circuit is in the zero state and the Count operations. Down Clock goes LOW. Since the TC outputs repeat the clock Each flip-flop contains JK feedback from slave to master waveforms, they can be used as the clock input signals to the such that a LOW-to-HIGH transition on its T input causes the next higher order circuit in a multistage counter.

All outputs of the flip-flop are simultaneously triggered on the low to high transi- tion of either clock while the other input isheld high. The direction of counting is determined by which input is clocked. When the LOAD input is taken low the data is loaded independently of either clock input. This feature allows the counters to be used as divide-by-n counters by modifying the count length with the preset inputs.
In addition the counter can also be cleared. All inputs are equipped with protection circuits against static discharge and transient excess voltage. Plastic Package. Ceramic Package. Micro Package.
