This enables the use of current limiting resistors to interface inputs to voltages in excess of V CC. The LM is a quadruple, independent, high-gain, internally compensated operational amplifiers designed to have operating characteristics similar to the LM This device is ideally suited for high speed bipolar memory chip select address decoding.

It features fully buffered inputs, each of which represents only one normalized load to its driving circuit. These devices contain four independent 2-input AND gates.

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 one inverter. Standard frequency crystals — use these crystals to provide a clock input to your microprocessor. Inputs include clamp diodes. All inputs are clamped with high-performance Schottky diodes to suppress line-ringing and to simplify system design. Add to cart Daatasheet More.


An enable input can be used as a data input datasheet demultiplexing applications. Features 74ls features include; Designed Specifically for High-Speed: 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.
