Logic IC 74138

In high-performance memory systems, these decoders can be used to minimize the effects of system decoding. After connecting the enable pins as shown in circuit diagram you can use the input line to get the output.

The chip is designed for decoding or de-multiplexing applications and comes with 3 inputs to 8 output setup. This amplifier exhibit low supply-current drain and input bias and offset currents that is much less than that of the LM The three buttons here represent three datazheet lines for the device. These devices contain four independent 2-input AND gates.

Drivers Motors Relay Servos Arduino.

As shown in table first three rows the enable pins needed to be connected appropriately or irrespective of input lines all outputs will be high.

Features 74ls features include; Designed Specifically for High-Speed: Product successfully added to your wishlist!

Submitted by admin on 26 October When employed with high-speed memories utilizing a fast enable circuit, the delay times of these decoders and the enable time of the memory are usually less than the typical access time of the memory.

The 74lS decode one of eight lines dependent on the conditions at the three binary select inputs and the three enable inputs. It features fully buffered inputs, each of which represents only one normalized load to its driving circuit. Choose an option 20 28 This means that the effective system delay introduced by the decoder is negligible to affect the performance. Here the outputs are connected to LED to show which output pin goes LOW and do remember the outputs of the device are inverted.

The design is also made for the chip to be used in high-performance memory-decoding or data-routing applications, requiring very short propagation delay times. This means that the effective system delay introduced by the Schottky-clamped system decoder is negligible. As mentioned earlier the chip is specifically designed to be used in high-performance memory-decoding or data-routing applications which require very short propagation delay times.

All of its essential components and connections are illustrated by graphic symbols arranged to describe operations as clearly as possible but without regard to the physical form of the various items, components or connections.

Also the chip inputs are catasheet with high-performance Schottky diodes to suppress line-ringing and simplify system design. TL — Programmable Reference Voltage.

Nye on Dec 29, Add to cart Learn More. An enable input can be used as a data input for demultiplexing applications. A line decoder can be implemented without external inverters and a datzsheet decoder requires only one inverter.

This device is ideally suited for high speed bipolar memory chip select address decoding.

The LM is a quadruple, independent, high-gain, internally compensated operational amplifiers designed to have operating characteristics similar to the LM This enables the use of current limiting resistors to interface inputs to voltages in excess of V CC.

The memory unit data exchange rate determines the performance of any application and the delays of any kind are not tolerable there. In high performance memory systems these decoders can be used to minimize the effects of system decoding. How to use 74LS Decoder For understanding the working of device let us construct a simple application circuit with a few external components as shown below. A line decoder can be implemented with no external inverters, and a line decoder requires only one inverter.
