This means that the effective system delay introduced by the decoder is negligible to affect the performance. The design is also made for the chip to be used in high-performance memory-decoding or data-routing applications, requiring datahseet short propagation delay times.

Logic IC 74138

A line decoder can be implemented without external inverters and a line decoder requires only jc inverter. Inputs include clamp diodes. Standard frequency crystals — use these crystals to provide a clock input to your microprocessor. This device is ideally suited for high speed bipolar memory chip select address decoding. Features and Electrical characteristics of 74LS Decoder Designed specifically for high speed Incorporates three enable pins to simplify cascading De-multiplexing 744138 Schottky clamped for high performance ESD protection Balanced propagation delays Inputs accept voltages higher than VCC Datashwet voltage: Features 74ls features include; Designed Specifically for High-Speed: You must be logged in to leave a review.

The 74lS decode one of eight lines dependent on the conditions at the three binary select inputs and the three enable inputs.

74LS Decoder Pinout, Features, Circuit & Datasheet

All inputs are clamped with high-performance Schottky diodes to suppress line-ringing and to simplify system design. 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 adtasheet to minimize the effects of system decoding. Wiring Diagram Third Level.

This enables the use of current limiting resistors to interface inputs to voltages in excess of V CC. Reviews 0 Leave A Review You must be logged in to 741138 a review.

Here the outputs are connected to LED to show which output pin goes LOW and do remember the outputs of the device are inverted. Also the chip inputs are clamped with high-performance Schottky diodes to suppress line-ringing and simplify system design.

Posted by Kirsten T. In high performance memory systems these decoders can be datashret to minimize the effects of system decoding.


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.

The three buttons here represent three input lines for the device.

After connecting the enable pins as shown in circuit diagram you can use the input line to get the output. Select options Learn More. Drivers Motors Relay Servos Arduino.

This amplifier exhibit low supply-current drain and input bias and offset currents that is much less than that of the LM 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. An enable input can be used as a data input for demultiplexing applications. 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.

Two active-low and one active-high enable inputs reduce the need for external gates or inverters when expanding. A line decoder can be implemented with no datasehet inverters, and a line decoder requires only one inverter. For understanding the working let us consider the truth table of the device. The LM is a quadruple, independent, high-gain, internally compensated operational amplifiers designed to have operating characteristics similar to the LM
