SN74LS161ADR: 4-bit Binary Counter from Texas Instruments
The SN74LS161ADR is a high-performance, 4-bit binary counter from Texas Instruments (TI), designed for use in a wide array of electronics applications requiring counting functionality. This integrated circuit is part of the 74LS series and is particularly suited for implementation in digital systems where low power consumption and high reliability are essential.
Constructed with Low Power Schottky (LPS) technology, the SN74LS161ADR offers a robust counter solution with a direct clear function. It features a fully synchronous design, ensuring that the outputs change coincident with each other when instructed by the count-enable inputs and the system clock.
This device can count in binary from 0 to 15, and it includes features such as a parallel-load capability that allows the counter to be preset to any desired value. The clear function is asynchronous, and it overrides all other inputs, ensuring that the counter can be quickly reset to zero when needed.
Specifications of the SN74LS161ADR include:
- 4-bit binary counting
- Asynchronous clear
- Parallel load capability
- Individual jam inputs
- Fully synchronous operation for count functions
- Direct clear function
- Operational temperature range: 0°C to 70°C
- Supply voltage range: 4.75V to 5.25V
- Standard TTL logic levels
Available in a small-outline package, the SN74LS161ADR is designed for space-efficient applications and is easy to integrate into a variety of digital systems. Its reliability and performance are backed by Texas Instruments' commitment to quality, making it a preferred choice for designers and engineers looking for a counter IC that delivers consistent results.
Whether you are designing digital counters, dividers, timers, or need a reliable component for other synchronous counting applications, the SN74LS161ADR from Texas Instruments is an excellent choice that combines functionality with performance in a compact package.
