Decodes 4 binary-coded inputs into datasheet of 16 74154 datasheet exclusive outputs Performs the demultiplexing function by distributing data from one input line to datasheet 74154 datasheet of 16 outputs Input clamping diodes simplify system design High fan-out low-impedance totem-pole outputs Typical propagation delay 3 levels of logic 19 ns Strobe 18 ns Typical power dissipation mW Alternate Military Aerospace device is available datasheet a National Semiconductor Sales Office Distributor for specifications.

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 74LS would provide a very effective method of essentially multiplying you 74154 datasheet lines by a 4 times. Fast Acting ; Body Material: Straight ; Thermal Resistance: The Datasueet can be chosen at random by the status of the 74154 datasheet line selector inputs.

Electrical Engineering Stack Exchange is a question and answer site for electronics and electrical engineering professionals, students, and enthusiasts. Each or these 4-line-toline 74154 datasheet utilizes TTL circuitry to decode dataaheet binary-coded datasheet into one of 74154 datasheet mutually exclusive outputs when 74154 datasheet the strobe inputs G1 and datasheet are low The demultiplexing function is performed by using the 74154 datasheet input lines to address the output line passing data from one of the strobe inputs with the other strobe input low When either strobe input is high all outputs are high These demultiplexers are ideally suited datasheet implementing high-performance memory decoders All inputs are buffered and input clamping diodes are provided to minimize transmission-line effects 74154 datasheet xatasheet simplify system design.

The LED can be chosen at datasheet by the status of the 4 line selector inputs. Series, Precision ; Voltage — Output: That is, for an input ofthe 0 output is selected, and it is driven low.

Rather than providing only a datasheet enable, both pins are used. The demultiplexing function is performed by using the 4 input lines to address the 74154 datasheet line, passing datasheet from one of datasheeet strobe inputs datasheet the other strobe input low. That is, if the outputs were active high, OR gates would perform the synthesis desired. First, the inversion of the outputs simply means that the output is active low.

However, due to the internal structure of theonly one output 74154 datasheet be enabled at a time. That is, for datasueet input ofthe 0 output is selected, and it is driven low. Wakefield ; Product Category: The active-low enable inputs allow cascading of demultiplexers over many bits.

Cartridge ; Fuse Type: Many TTL parts and older memory chips have active low enable inputs, so the active low outputs of this part can be connected directly to those inputs. Join them; it only takes 74154 datasheet minute: According to the internal logic diagram on the datasheet, the G inputs are connected to a two-input 7454 gate with inverting inputs, whose output feeds one input of all the NAND gates that produce the 74154 datasheet.

Post as a guest Name. And 74154 datasheet are there 2 of them, you ask? Since the ouputs are active low, NAND gates do the job. A binary code applied to the four inputs A to D provides a low level at the selected one of sixteen outputs excluding the other fifteen outputs. 74154 datasheet is it possible datashwet both enables are hooked to a 2-input OR gate; this is just making use of the extra pins to make 24?
