This device is ideally suited for high speed bipolar memory chip select address decoding. In high-performance memory systems, these decoders can be used to minimize the effects of system decoding.
When employed with dedoder 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. This means that the effective system delay introduced by the Schottky-clamped system decoder is negligible. The 74lS decode one of eight lines dependent on the conditions at the three binary select inputs and the three enable inputs.
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 without external inverters and a line decoder requires only ddcoder inverter. An enable input can be used as a data input for demultiplexing applications.

It features fully buffered inputs, each of which represents only one normalized load to its driving circuit. All inputs are clamped with high-performance Schottky diodes to suppress line-ringing and to simplify system design. You must be 7138 in to leave a review. Standard frequency crystals — use these crystals to provide a clock input to your microprocessor. These devices contain four independent 2-input AND gates.
The LM is a quadruple, independent, high-gain, internally compensated operational amplifiers designed to have operating characteristics similar to the LM This amplifier exhibit low supply-current drain and input bias and offset currents that is much less than that of the LM Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of V CC.
