The Texas Instruments 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, featuring two active-low and one active-high enable for simplified cascading.
This device is suitable for high-speed memory systems where minimal decoding delay is critical. The integrated Schottky diodes suppress line-ringing, simplifying system design. The SN54S138J is characterized for operation over the full military temperature range of -55°C to 125°C.
Key specifications include 8 outputs, 3 select inputs, and 3 enable inputs. The package is a 16-pin CDIP, supplied in tubes with a standard quantity of 25 units. Its logic family is Schottky TTL, making it ideal for applications requiring fast propagation times.
