4-line to line Decoders/demultiplexers. Each or these 4-line-toline decoders utilizes TTL circuitry to decode four binary-coded inputs into one of. MOS technology. 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. SNN .. of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration.

Y Alternate Military Aerospace device is avail. 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. And why are there 2 of them, you ask?

According to the internal logic diagram on the datasheet, the G inputs are connected to a two-input AND gate with inverting inputs, whose output feeds one input of all the NAND gates that produce the outputs.


Office Distributors for availability and specifications. Y High fan-out low-impedance totem-pole outputs. WhatRoughBeast 49k 2 28 Since the ouputs are active low, NAND 74514 do the job.

74154 Datasheet

Sign up or log in Sign up using Google. Note 2 Not more than one output should be shorted at a time. Each of the 16 datasheft can be connected through a resistor and then through an LED to serve as a simple 16 LED controller.

When either strobe input is high, all outputs are high.

Low Level Input Current. There are datssheet two enable inputs because otherwise there would be two unused pins on the 24 pin package I don’t recall seeing 22 pin DIP packages.

Each or these 4-line-toline decoders utilizes TTL circuit. If Military Aerospace specified devices are required. My first question is more important Download the datasheet below for a more comprehensive summary. Electrical Characteristics over recommended operating free air temperature range unless otherwise noted.

Note 3 I CC is measured with all outputs open and all inputs grounded. Rather than providing only a single enable, both pins are used. High Level Input Voltage. All the other ouputs stay high.

4 to 16 decoder logic diagram – Electrical Engineering Stack Exchange

I am a new user so I didn’t know I had that power. High to Low Level Output. I OS Short Circuit. All inputs are buffered and input clamping diodes are provided to minimize transmission-line effects and thereby simplify system design.

Post as a guest Name. This chip is often used in demultiplexing applications, such as digital clocks, LED matrices, and other graphical outputs.
