Xytronic 74LS193 Major Brands Synchronous Binary Features
-
A clear input has been provided which, when taken to a high level, forces all outputs to the low level;
-
These counters were design to be cascaded without the need for external circuitry. Both borrow and carry outputs are available to cascade both the up and down counting functions
-
The counters can then be easily cascaded by feeding the borrow and carry outputs to the count down and count up inputs respectively of the succeeding counter
-
Independent of the count and load inputs. The clear, count, and load inputs are buffered to lower the drive requirements of clock drivers, etc., required for long words
-
The borrow output produces a pulse equal in width to the count down input when an overflow condition exists
About Xytronic 74LS193 Major Brands Synchronous Binary
This is a CMOS 8-bit successive approximation A/D converter that uses a differential potentiometric ladder-similar to the 256R products. This converter is designed to allow operation with the NSC800 and INS8080A derivative control bus with TRI-STATE output latches directly driving the data bus. This A/D appears like memorylocations or I/O ports to the microprocessor and no interfacing logic is needed.
