Frequently Asked Questions
What are the key electrical specifications of the SN74LS293D?
The SN74LS293D operates with a load capacitance (CL) of 15pF and belongs to the LS (Low-power Schottky) logic family. It features a JESD-30 package code of R-PDSO-G14 (SOIC-14) and is rated with a JESD-609 code of e4, confirming Pb-free RoHS compliance. The device supports up-count direction and includes asynchronous master reset functionality.
What applications is the SN74LS293D suitable for?
The SN74LS293D is ideal for digital frequency division, clock generation, and modulo-N counting applications. Its divide-by-2 and divide-by-8 sections can be cascaded to implement custom count sequences. Common use cases include timing circuits in communication equipment, industrial controllers, microcontroller interface logic, and digital prototyping systems.
What package does the SN74LS293D come in and are there alternative packages?
The SN74LS293D is available in a 14-pin Small Outline Integrated Circuit (SOIC) package, designated R-PDSO-G14. The 'D' suffix in the part number specifically denotes this SOIC-14 package. Texas Instruments also offers the SN74LS293N in a DIP-14 through-hole package for breadboard prototyping, making it easy to select the right form factor for your PCB design.
How do I reset the SN74LS293D counter?
The SN74LS293D features an asynchronous master reset (MR) input that immediately clears all counter outputs to zero when asserted high, regardless of the clock state. This allows for flexible initialization in system startup sequences or mid-operation resets. The reset is independent of the clock signal, ensuring deterministic behavior in time-critical digital designs.
