SN74ALS169BDR from Texas Instruments

The SN74ALS169BDR is a high-performance integrated circuit from Texas Instruments, designed for use in a wide range of digital applications. This device is part of the advanced low-power Schottky (ALS) family, which is known for combining the low power consumption of CMOS with the speed and drive characteristics of bipolar transistors. The SN74ALS169BDR is a binary up/down counter that is ideal for use in computer systems, instrumentation, and other digital logic applications where a reliable and efficient counting solution is required.

The SN74ALS169BDR is a 4-bit synchronous reversible counter that can count in both up and down modes. It features a fully synchronous internal architecture, which ensures that the output transitions occur simultaneously on the next clock pulse, without any ripple effect. This synchronous design allows for higher counting speeds and more reliable operation, especially in systems where timing is critical.

This device offers a variety of features that make it versatile and easy to use. It includes a clear function, which can be used to reset the counter to zero, as well as preset inputs for setting the counter to a specific initial value. The counter also has output carry and borrow signals, which can be used to implement multi-stage counter configurations or to interface with other digital components.

The SN74ALS169BDR is packaged in a slim 16-pin SOIC package, which makes it suitable for use in space-constrained applications. It operates over a wide range of supply voltages, from 4.5V to 5.5V, and offers a typical power dissipation of only 1 mW per gate. This low power consumption, combined with its high speed and drive capabilities, makes the SN74ALS169BDR an excellent choice for portable and battery-powered devices, as well as for high-speed computing and processing applications.

As with all Texas Instruments products, the SN74ALS169BDR is manufactured to the highest quality standards and is backed by the company's extensive support and reliability data. Whether you are designing a new system or upgrading an existing one, the SN74ALS169BDR is a reliable and cost-effective choice for your counting and digital logic needs.
