Description
Electronic Component Model: LS393 is a monolithic circuit that contains eight master-slave flip-flops and additional gating to implement two individual four-bit counters in a single package. It is a dual version of the popular DM74LS93.
Specifications and features
- Each package can implement N-bit binary counters, providing the capability of divide-by-256.
- The LS393 has parallel outputs from each counter stage, allowing for system-timing signals.
- It features a direct clear for each 4-bit counter and individual clocks.
- The dual 4-bit versions of the LS393 can significantly improve system densities by reducing counter package count by 50%.
- It has a typical maximum count frequency of 35 MHz.
- The buffered outputs of the LS393 reduce the possibility of collector commutation.
Application Scenarios
The LS393 is commonly used in applications that require counting and dividing signals, such as frequency dividers, timekeeping circuits, and digital systems that require precise timing.
Comparison
Advantages- Contains two individual four-bit counters in a single package, saving space and reducing system density
- Capable of implementing N-bit binary counters, providing flexibility in dividing signals
- Parallel outputs from each counter stage allow for system-timing signals
- Direct clear for each 4-bit counter and individual clocks for precise control
Disadvantages- Maximum count frequency of 35 MHz may be insufficient for some high-speed applications
- Possibility of collector commutation, although buffered outputs help reduce this
