Logic IC 74138

This means that the effective system delay introduced by the Schottky-clamped system decoder lc negligible. A line decoder can be implemented without external inverters and a line decoder requires only one inverter. The LM is a quadruple, independent, high-gain, internally compensated operational amplifiers designed to have operating characteristics similar to the LM This means that the effective system delay introduced by the decoder is negligible to affect the performance.

Wiring If Third Level.

For understanding the working let us consider the truth table of the device. Product successfully added to your wishlist! All inputs are clamped with high-performance Schottky diodes to suppress line-ringing and to simplify system design. The three enable pins if chip in which Two active-low and one active-high reduce the need for external gates or inverters when expanding.

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

This enables the use of current limiting resistors to interface inputs to voltages in excess of V CC. In such applications using 74LS line decoder is ideal because the delay times of this device are less than the typical access time of the memory. Also the chip inputs are clamped with high-performance Schottky diodes to suppress line-ringing and simplify system design. For understanding the working of device let us construct a simple application circuit with a few external components as shown below.

Product already added to wishlist! Here the outputs are connected to LED to show which output pin goes LOW and do remember the outputs of the device are inverted. Features and 74318 characteristics of 74LS Decoder Designed i for high speed Incorporates three enable pins to simplify cascading De-multiplexing capability Schottky clamped for high performance ESD protection Balanced propagation delays Inputs accept voltages higher than VCC Supply voltage: Choose an option 20 28 In high performance memory systems these decoders can be used to minimize the effects of system decoding.

A line decoder can be implemented with no external inverters, and a line decoder requires only one inverter. 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.

Select options Learn More. This way we can realize all the truth table by toggling the three buttons B1, B2 and B3 Three inputs A0, A1 and A2 and with that we have three input to eight output decoder. Add to cart Learn More.

The chip is designed for decoding or de-multiplexing applications and comes with 3 inputs to 8 output setup. How to use 74LS Decoder For understanding the working of device let us construct a simple application oc with a few external components as shown below. TL — Programmable Reference Voltage. 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.

These devices contain four independent 2-input AND gates.

This amplifier exhibit low supply-current drain and input bias and offset currents that is much less than that of the LM The 74lS decode one of eight lines dependent on the conditions at the three binary select inputs and the three enable inputs.

Description Resources Learn Videos Blog 74ls Schottky-clamped TTL MSI circuits are designed to be used in high-performance memory decoding or data-routing applications requiring very short propagation delay times.

In high-performance memory systems, these decoders can be used to minimize the effects of system decoding. This device is ideally suited for high speed bipolar memory chip select address decoding. Submitted by admin on 26 October As shown 741138 table first three rows the enable pins ci to be connected appropriately or irrespective of input lines all outputs will 741338 high.
