SN74293N TI Counter IC | DIP-14 | 4-Bit Binary, Asynchronous Reset

Product Overview

The SN74293N is a 4-bit binary counter manufactured by Texas Instruments, featuring asynchronous reset functionality. It is part of the 74xx series logic family and is designed for high-speed counting applications. The device operates from a single 5V power supply and is available in a 14-pin DIP package. It counts in binary sequence from 0 to 15 and resets to zero when the reset input is activated. The SN74293N is ideal for use in frequency division, timing circuits, and digital systems requiring reliable counting.
