Counter Dividers datasheet and documents for SN74LS169N
Counter Dividers Overview
The SN74LS169N is a synchronous, positive edge-triggered 4-bit bidirectional binary counter manufactured by onsemi. It operates within the LS logic series and is housed in a 16-pin PDIP package. The device supports up-counting and down-counting modes controlled by an external input. It features parallel data loading capabilities via dedicated inputs and includes asynchronous clear and ripple clock outputs for cascading applications.
Counter Dividers Feature Summary
- Synchronous operation triggered by positive clock edges
- Bidirectional counting capability with up/down control
- Asynchronous master reset function
- Parallel data load interface
Counter Dividers Applications
- Digital frequency division circuits
- Time base generation systems
- Event sequence counters
- Cascaded multi-stage digital counters
Counter Dividers Procurement Notes
Verify the manufacturer marking matches onsemi specifications. Confirm the package type is DIP-16. Check for lead-free compliance status if required by project regulations. Ensure the part number suffix corresponds to the correct speed grade and temperature range defined in the official datasheet.
Counter Dividers Selection Notes
Select this component when a synchronous 4-bit bidirectional counter is required. Compare propagation delays against system timing requirements. Verify voltage levels match the target logic family. Consider pin compatibility with existing PCB layouts designed for standard DIP-16 packages.
Counter Dividers Part Context
This component belongs to the SN74LSxx series of low-power Schottky TTL logic devices. It provides high-speed switching characteristics compared to standard LS logic while maintaining compatible pinouts. The series is widely used in industrial and commercial digital systems requiring reliable binary counting functions.
Counter Dividers Replacement Considerations
Compatible substitutes include SN74LS163N for unidirectional counting or SN74HC169N for CMOS-level operation. Verify voltage tolerance and speed parameters before substitution. Ensure functional equivalence regarding preset and clear mechanisms.
