This SDLS105 file is about SN5438, SN54LS38, SN54S38 SN7438, SN74LS38, SN74S38 QUADRUPLE 2-INPUT POSITIVE-NAND BUFFERS WITH OPEN-COLLECTOR OUTPUTS, including information such as package type, pin count, production process, etc.
The document describes the SN5438, SN54LS38, SN54S38, SN7438, SN74LS38, and SN74S38 devices, which are quadruple 2-input positive-NAND buffers with open-collector outputs. These components require external pull-up resistors for correct operation and can be connected to implement wired-OR or wired-AND functions.
