Frequently Asked Questions
How can I reset the counter?
Applying a LOW level at the master reset input (MR) sets all flip-flops to LOW, performing an asynchronous reset.
What is the maximum operating frequency for cascaded counters?
The maximum clock frequency is determined by CE_P to TC propagation delay and CEP synchronous operation time: f = 1 / [t(CE_P to TC) + t(CEP to CP)].
How do I stop counting without resetting the counter?
Applying a LOW level at the parallel enable input (PE) disables the counting action, allowing external data (D to D) to be loaded.
Which function provides an asynchronous clear capability?
The combination of standard outputs ($Q_n$ to $Q_n$) and the terminal count output (TC) can provide an asynchronous clear function when controlled by levels at CP, PE, CET, and CEP inputs.
