The SN54LS04J is a 14-pin ceramic dual in-line package (CDIP) tube manufactured by Texas Instruments. It is a bipolar transistor inverter containing 6 elements intended for use in digital systems. It is constructed using different layers of the semiconductor material silicon, which is capable of controlling and amplifying current. With its high speed performance, it is suitable for applications such as interfacing between different integrated circuits and providing logic system output. With its low power consumption, it also helps to reduce power bills due to less heat dissipation. It provides high fan-out of ten, which helps to drive a number of low power loads. It has an operating voltage range of 3-15V and a maximum propagation delay of 30 ns. It is available in a variety of packages, including 14-pin CDIP, 14-pin plastic dual in-line package (PDIP), 14-pin small outline package (SOIC), and 14-pin shrink small outline package (SSOP).
