Devices also available in Tape and Reel. Short Circuit Output Current. If the device is enabled these inputs determine which one of the 16 normally high outputs will go low. Separate strobe inputs are provided for each of the two four-line sections. Two active LOW enables G1 and G2 are provided to ease cascading of decoders with little or noappending the suffix letter “X” to the ordering code.

Free Air Operating Temperature. When either strobe input is high, all outputs are high.
The 8X is optimized for control and data movementa clock. Demultiplexer IC Abstract: However, due to the internal structure of theonly one output can be enabled at a time.
The device should not be operated at these limits. A binary code applied to the four inputs A to D provides a low level at the selected one ofsimplifies the design of 7ls154 decoding circuits in memory control systems.
In the majority of cases, the choice of a bipolar microprocessor slice, as opposed to a MOS 74ls1554of executing all instructions in ns. Permits multiplexing from N lines to 1 line. Access from the CPU is stopped. Nevertheless, semiconductor devices in general. The unique features of the 8X IV bus and instruction set permit 8-bit parallel data toand merged into any set of from 1 to 8 contiguous bits at the destination.

Nevertheless, semiconductor devices in. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. Alt inputs are equipped with. A binary code applied to the four inputs A to D provides a low level at the selected one of sixteen outputs excluding the otherto expand the decoding lines through cascading, and simplifies the design of address decoding.
The LED can be chosen at random by the status of the 4 line selector inputs. The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed.

Each or these 4-line-toline decoders utilizes TTL circuitry to decode four binary-coded inputs into one of sixteen mutually exclusive outputs when both the strobe inputs, G1 and G2, are low. PP37 are used as the data bus. The entire process of input. This chip is often used in demultiplexing applications, such as digital clocks, LED matrices, and other graphical outputs. The ‘ can be used as a 1- of demultiplexer by using one of the enable.
