Product Overview: SN74AS169ADR - Texas Instruments

The SN74AS169ADR is a high-performance, 4-bit synchronous up/down binary counter designed by the renowned semiconductor manufacturer, Texas Instruments. This integrated circuit is part of the Advanced Schottky (AS) logic family, which is well-known for its high-speed operation and improved output drive capabilities, making it an excellent choice for a wide range of digital applications.

Featuring dual clock inputs, the SN74AS169ADR provides the flexibility to count up or down, depending on the configuration of the count-enable inputs and the up/down input. The clear function is synchronous, ensuring that the count can be reset to zero during a clock pulse rather than between clock pulses, which enhances the precision of timing operations.

The counter advances on the low-to-high transition of the clock input while the count-enable inputs are at the appropriate level. A built-in carry look-ahead capability allows for cascading counters to create extended counting ranges without significant delays. This makes the SN74AS169ADR ideal for applications requiring precise multi-stage counting, such as digital clocks, frequency counters, and digital event counters.

The SN74AS169ADR is packaged in a slim SOIC-16 package, offering a compact footprint suitable for space-constrained applications. Its wide operating temperature range ensures reliable performance in various environmental conditions. Additionally, the device is fully specified for partial-power-down applications using Texas Instruments' Ioff specification, which ensures that the input circuitry does not load the data bus when the device is powered down.

With its robust feature set and Texas Instruments' commitment to quality, the SN74AS169ADR is an exceptional choice for designers seeking a dependable and efficient binary counter for their digital systems. Whether used in industrial control systems, data processing units, or communication devices, this component delivers the performance and reliability expected from a leading semiconductor product.
