SN54LS669 Overview
Key Specifications
Package: CDIP
Mount Type: Through Hole
Pins: 16
Operating Voltage: 5 V
Key Features
- an internal carry lookahead for cascading purposes
- This helps to eliminate output counting spikes, normally associated with asynchronous (ripple-clock) counters
- The four master-slave flip-flops are triggered on the rising (positive-going) edge of the clock waveform by a buffered clock input
- Circuitry of the load inputs allows loading with the carry-enable output of the cascaded counters
- Cascading counters for N-bit synchronous applications are provided by the carry look-ahead circuitry, without additional gating
