Compare 741 price and availability by authorized and independent electronic component distributors. The following is a list of 7400 series digital logic integrated circuits.The SN7400 series originated with TTL integrated circuits made by Texas Instruments.Because of the popularity of these parts, they were second-sourced by other manufacturers who kept the 7400 sequence number as an aid to identification of compatible parts. 74154 4-16 line decoder/demultiplexer: IC 74154 is a 4-16 line decoder, it takes the 4 line BCD input and selects respective output one among the 16 output lines. It is active low output IC so when any output line is selected it is indicated by active low signal, rest of the output lines will remain active high.

Both of these must be low to make the output (selected by the address) go low. The LSTTL/MSI SN54/74LS138 is a high speed 1-of-8 Decoder/ Demultiplexer. This device is ideally suited for high speed bipolar memory chip select address decoding. The multiple input enables allow parallel ex-pansion to a 1-of-24 decoder using just three LS138 devices or to a 1-of-32 decoder using four LS138s and one inverter.
TX-2B / RX-2B is a remote encoder decoder pair that can be used for remote control applications. TX-2B / RX-2B has five channels, wide operating voltage range (from 1.5V to 5V), low stand by current (around 10uA), low operating current (2mA), auto power off function and requires few... I thought about using a 74154 as a crude address decoder for the top four address lines, which would seem to work for adding eight 8-bit chips, but I noticed only SRAM tends to have the chip enable pin, and it's next to impossible to get 64kx8 SRAM in DIP. Also I notice the PCjr uses DRAM by default, and I am unsure if that poses some kind of ... 74139 Dual 2-to-4 line decoder/demultiplexer. ...

Give the definition, syntax and potential use of a VHDL constant data object. 2. Perform an Internet search and find a datasheet for the 74154 4- to-16 decoder. From the functional description given in the data sheet, write a VHDL description for a 74154 4-to-16 decoder.
74154 (mostly 74LS154, 74HC154, 74HCT154) - 4-Line to 16-Line Decoder/Demultiplexer 74155 (mostly 74LS155, 74HC155, 74HCT155) - Dual 2-Line to 4-Line Decoder/Demultiplexer 74156 (mostly 74LS156, 74HC156, 74HCT156) - Dual 2-Line to 4-Line Decoder/Demultiplexer with Open Collector Outputs The RESET (=CLEAR) input of the 7474 is driven by the selected state of a 74154 decoder, which is connected to a 7493, as in Lab 2. Since the CLEAR is activated by a LOW, the FF will clear when the selected state (0) is reached. The 7493 is reset (set to zero) when the Q of the 7474 goes HIGH.
Sep 02, 2008 · 74154 4-16 line decoder/demultiplexer: IC 74154 is a 4-16 line decoder, it takes the 4 line BCD input and selects respective output one among the 16 output lines. It is active low output IC so when any output line is selected it is indicated by active low signal, rest of the output lines will remain active high. ■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL ■ WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V. ■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 154 DESCRIPTION The M74HC154 is an high speed CMOS 4 TO 16 LINE DECODER/DEMULTIPLEXER fabricated with silicon gate C2MOS technology.
Zou iemand mij kunnen uitleggen hoe een 1 to 16 decoder/multiplexer precies werkt? Ik heb de datasheet doorgelezen, maar juist het gedeelte van 1 input i.p.v. van 4 snap ik niet helemaal. The 74F154 can be used as 1-of-16 demultiplexer by using one of the Enable inputs as the multiplexed data input. When the other List of 7400 series integrated circuits.
