SN74ALS869 Overview
Key Specifications
Package: SOIC
Mount Type: Surface Mount
Pins: 24
Operating Voltage: 5 V
Description
These synchronous, presettable, 8-bit up/down counters feature internal-carry look-ahead circuitry for cascading in high-speed counting applications. Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincidentally with each other when so instructed by the count-enable (ENP, ENT) inputs and internal gating.
Key Features
- internal-carry look-ahead circuitry for cascading in high-speed counting applications
- This mode of operation eliminates the output counting spikes normally associated with asynchronous (rippleclock) counters
- A buffered clock (CLK) input triggers the eight flip-flops on the rising (positivegoing) edge of the clock waveform
- SN54AS867, SN54AS869
