Asynchronous parallel load capability permits the counter to be preset to any desired number. This feature simplifies the design of multistage counters as shown in Figure 5 and Figure 6. The TC output of a given.

The timing skew between state changes in the first and last stages is represented by the cumulative delay of the clock as it ripples through the preceding stages. This operation overrides the counting function. Do not use the TC output as a clock signal because it is subject to decoding spikes.

Measurement points are given in Table 9. 74h191

Functional description Table 3. Dynamic characteristics Table 8.
