The SN54LS14J is a 6-element bipolar transistor inverter Schmitt trigger manufactured by Texas Instruments. It is a 14-pin Ceramic Dual In-line Package (CDIP) tube, which is a type of surface-mount packaging. This device enables an input signal to switch between two different voltage levels without requiring the use of an external load. The SN54LS14J is equipped with hysteresis, which allows it to respond differently to both increasing and decreasing input signals. It has an operating voltage of 4.5 V to 5.5 V, and can handle frequencies up to 1 MHz. This makes it suitable for various digital logic applications, including oscillators, flip-flops, and memory latch control circuits. Additionally, the SN54LS14J is designed to have a low power consumption of under 50 µW, making it an energy-efficient solution.
