SN54LS08J

Overview

The SN54LS08J is a quadruple 2-input positive-AND gate manufactured by Texas Instruments. It operates within a military-grade temperature range of -55°C to 125°C and utilizes a 14-pin ceramic dual in-line package (CDIP). The device belongs to the LS TTL series, featuring four independent logic functions with two inputs each. Key electrical characteristics include a maximum output low current of 0.016 A and a load capacitance of 15 pF.
