It contains four edge-triggered flip-flops, with internal gating and steering logic to provide master reset, individual preset, count up and count down operations. A LOW-to-HIGH transition on the CP input to each flip-flop causes the output to change state. Synchronous switching, as opposed to ripple counting, is achieved by driving the steering gates of all stages from a common Count Up line and a common Count Down line, thereby causing all state changes to be initiated simultaneously. A LOW-to-HIGH transition on the Count Up input will advance the count by one; a similar transition on the Count Down input will de- crease the count by one. While counting with one clock in- put, the other should be held HIGH, as indicated in the Function Table. Otherwise, the circuit will either count by twos or not at all, depending on the state of the first flip-flop, which cannot toggle as long as either clock input is LOW. The Terminal Count Up (TC U) and Terminal Count Down (TCD) outputs are normally HIGH. When the circuit has reached the maximum count state 9, the next HIGH-to-LOW transition of the Count Up Clock will cause TC U to go LOW. TCU will stay LOW until CP U goes HIGH again, thus effec- tively repeating the Count Up Clock, but delayed by two gate delays. Similarly, the TC D output will go LOW when the circuit is in the zero state and the Count Down Clock goes LOW. Since the TC outputs repeat the clock waveforms, they can be used as the clock input signals to the next higher order circuit in a multistage counter. TC U e Q0 # Q3 # CPU TCD e Q0 # Q1 # Q2 # Q3 # CPD The ’F192 has an asynchronous parallel load capability per- mitting the counter to be preset. When the Parallel Load (PL ) and the Master Reset (MR) inputs are LOW, informa- tion present on the Parallel Data input (P 0 –P3) is loaded into the counter and appears on the outputs regardless of the conditions of the clock inputs. A HIGH signal on the Master Reset input will disable the preset gates, override both clock inputs, and latch each Q output in the LOW state. If one of the clock inputs is LOW during and after a reset or load operation, the next LOW-to-HIGH transition of that clock will be interpreted as a legitimate signal and will be counted.
