74192 Up/Down counter problems... All About Circuits
18/01/2012 · The 74HC191 is a 4-bit up/down Binary counter. Once you figure out how it works (use a simulation program), connect a 7447 or 74247 to the binary outputs. Once you figure out how it works (use a simulation program), connect a 7447 or 74247 to the binary outputs.... To convert the up counter in Fig. 5.6.1 to count DOWN instead, is simply a matter of modifying the connections between the flip-flops. By taking both the output lines and the CK pulse for the next flip-flop in sequence from the Q output as shown in Fig. 5.6.3, a positive edge triggered counter will count down from 1111 2 to 0000 2 .

Counter Wikipedia
The up/dn input, for example, tells the counter to count up if it is a logic 1, or down when it is logic 0. In the same way, a logic 1 to the bin/dec input causes the counter to operate in binary mode, while a logic 0 switches it to decimal (sometimes called decade ) mode. how to download and install xbox games MC14516B Binary Up/Down Counter The MC14516B synchronous up/down binary counter is constructed with MOS P−channel and N−channel enhancement mode devices in a monolithic structure. This counter can be preset by applying the desired value, in binary, to the Preset inputs (P0, P1, P2, P3) and then bringing the Preset Enable (PE) high. The direction of counting is controlled by applying a …. How to change ip address for american netflix
