SN74LS90N TI Decade/Binary Counter | 14-PDIP | 4-Bit, LS Family

Product Overview

The SN74LS90N is a monolithic 4-bit decade and binary counter from Texas Instruments, part of the 74LS family. It features a high-speed, low-power Schottky design and is housed in a 14-pin PDIP package. The device can be configured as a divide-by-2 and divide-by-5 counter, enabling decade (BCD) or binary (4-bit) counting modes. It is ideal for frequency division, timing, and counting applications in industrial and consumer electronics.
