Key Features
- Synchronous 8-bit binary down counter.
- Control inputs for enabling or disabling the clock (CP), clearing the counter to its maximum count, and presetting the counter either synchronously or asynchronously.
- Terminal count output (TC) goes LOW when the count reaches zero if the terminal enable input (TE) is LOW.
- Data at the jam inputs (P0 to P7) can be clocked into the counter on the next positive-going clock transition when the synchronous preset enable input (PE) is LOW.
- Data at the jam inputs (P0 to P7) can be asynchronously forced into the counter when the asynchronous preset enable input (PL) is LOW.
- Operates within a temperature range of -40 °C to +125 °C.
Applications
- Divide-by-n counters.
- Programmable timers.
- Interrupt timers.
- Cycle/program counters.
- Automotive and industrial applications.
- Power, computing, consumer, mobile, and wearable devices.
