SN74ALS569ANS TI Synchronous Up/Down Counter | 4-Bit, 20MHz

Product Overview

The SN74ALS569ANS is a high-performance 4-bit synchronous up/down counter from Texas Instruments, designed for use in advanced digital systems. It features a fully independent clock circuit, enabling synchronous counting in either direction. The device includes a clear function to reset the outputs to zero and a load function to preset the counter to any 4-bit value. With a typical clock frequency of 20 MHz, it is suitable for high-speed applications. The SN74ALS569ANS is offered in a 20-pin SOP package, providing a compact solution for space-constrained designs.
