The Texas Instruments SN74S138AN is a Schottky-clamped TTL MSI circuit designed for high-performance memory decoding or data-routing applications requiring very short propagation delay times. This decoder/demultiplexer can decode one of eight lines based on three binary select inputs and three enable inputs. It features two active-low and one active-high enable inputs, simplifying cascading and data reception without external gates or inverters.
This device is suitable for high-speed memory systems where minimizing system decoding effects is crucial. When used with high-speed memories, the decoder's delay times are typically less than the memory's access time, resulting in negligible system delay. The SN74S138AN operates from a single supply voltage of 4.75V to 5.25V and has an operating temperature range of 0°C to 70°C.
Packaged in a 16-PDIP (0.300", 7.62mm) through-hole configuration, it is designed for applications requiring robust performance and ease of system integration. All inputs are clamped with high-performance Schottky diodes to suppress line-ringing and simplify system design.
