The SN54S138J is a Schottky-clamped TTL MSI circuit designed for high-performance memory decoding and data-routing applications. It decodes one of eight lines based on three binary select inputs and three enable inputs. The device features three enable inputs, two active-low and one active-high, which simplify cascading and data reception, reducing the need for external gates.
This decoder/demultiplexer is suitable for high-speed memory systems where minimizing decoding delay is critical. Its Schottky clamping ensures high performance and suppresses line-ringing. The SN54S138J is characterized for operation over the full military temperature range of -55°C to 125°C.
Packaged in a 16-pin CDIP (J) package, it is supplied in tubes with a package quantity of 25. The device features fully buffered inputs, each representing a single normalized load. All inputs are clamped with high-performance Schottky diodes to simplify system design.
