Texas Instruments SN54F138 3-Line To 8-Line Decoders/Demultiplexers JM38510/33701B2A

The SN54F138 is a 3-line to 8-line decoder/demultiplexer designed for high-speed memory decoding and data transmission applications. It features three enable inputs, allowing for simplified cascading and data reception, which can reduce the need for external gates or inverters. The device is characterized for operation over a military temperature range of -55¬8C to 125¬8C, making it suitable for demanding environments. This decoder can effectively minimize system decoding delays when used with high-speed memory systems, as its propagation delay times are typically less than the access times of the memories it interfaces with. The SN54F138 supports the selection of one of eight output lines based on the binary-select inputs and enable inputs, making it versatile for various applications. The product is available in multiple package options, including LCCC and CDIP, accommodating different design requirements.
