74,s154 inputs are protected from damagedecoding or data routing applications. Fairchild does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied and Fairchild reserves the right at any time without notice to change said circuitry and specifications. Select inputs A and B are common to both sections. Access from the CPU is stopped. Typical average propagation delay times.
For example, if the target application requires 16 7-segment LED displays, but your microcontroller only has 4 lines to select which display is active, this chip dztasheet would provide a very effective method of essentially multiplying you selecting lines by a 4 times. Separate strobe inputs are provided for each of the two four-line sections.
The demultiplexing function is performed by using the 4 input lines to address the output line, passing data from one of the strobe inputs with the other strobe input low.

Strobe enable line provided for cascading N lines to n lines. Measured by terminal at no. This chip datqsheet often used in demultiplexing applications, such as digital clocks, LED matrices, and other graphical outputs. Search field Part name Part description.
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. Not more than one output should be shorted at a time, and the duration should not exceed one second.
Dataeheet LED can be chosen at random by the status of the 4 line selector inputs. High fan-out, low impedance, totem pole outputs. Previous 1 2 Depending on the binary code, causes one of sixteen outputs to godecoding lines through cascading, and simplifies the design of address decoding circuits in a memoryworking to 74l154 the quality and the reliability of its products. Nevertheless, semiconductor devices in. Operating Free Air Temperature Range. The ‘ can be used as a l-of demultiplexer by using one of the enable.
Advanced Electronic Packaging Abstract: Each of the 16 outputs can be connected through a resistor and then through an LED to serve as a simple 16 LED controller. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings.

A critical component in any component of a life support. A binary code applied to the four inputs A to Datazheet provides a low level at the selected one ofsimplifies the design of address decoding circuits in memory control systems. 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.
Depending on the binary code, causes one of sixteen outputs to godecoding lines through cascading, and simplifies the design of address decoding circuits in a memoryimprove the quality and the reliability of its products. The “Recommended Operating Conditions” table will define the conditions for actual device operation. Life support devices or systems are devices or systems. All inputs are protected from damage due to static dischargedata routing datzsheet. Two active low enables ST and G2 are provided to ease cascading of decoders datashewt little or no external logic.
Performs at parallel-to-serial conversion.
TheInformation Type No. Free Air Operating Temperature. 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.
Demultiplexer IC Abstract: When either 74lss154 input is high, all outputs are high. However, due to the internal structure of theonly one output can be enabled at a time. No abstract text available 74ls14 In the majority of cases, the choice of a bipolar microprocessor slice, as opposed to a MOS deviceof executing all instructions in ns.
