SN74LV161APWT: A 4-Bit Binary Counter from Texas Instruments

The SN74LV161APWT is a high-performance, 4-bit binary counter designed and manufactured by Texas Instruments (TI), a leader in the semiconductor industry. This integrated circuit is part of the LV family, which stands for 'Low-Voltage'. It operates on a low power supply range of 2V to 5.5V, making it suitable for battery-operated applications and portable devices.

One of the key features of the SN74LV161APWT is its synchronous operation. The counter advances on the rising edge of the clock signal, providing precise timing and control. This feature allows for reliable and predictable counting sequences in digital systems, ensuring that timing errors are minimized.

The device is equipped with a clear function, which when activated, resets the counter to its zero state, regardless of the clock input or other conditions. This is particularly useful for initializing the counter at the start of an operation or for resetting it in the case of an error or other event that requires the counter to start over.

The SN74LV161APWT also offers a fully synchronous serial or parallel data input capability. This means that data can be loaded into the counter without glitches, as the loading operation is synchronized with the clock signal. The outputs of the counter are buffered, which provides low drive and high performance, allowing the counter to drive loads without significant signal degradation.

This product is available in a 16-pin TSSOP (Thin Shrink Small Outline Package) package, which is designed to be space-efficient, making it an excellent choice for compact electronic designs. The SN74LV161APWT is characterized for operation from -40°C to 85°C, ensuring reliable performance across a wide range of environmental conditions.

Whether used in microprocessors, digital timers, frequency dividers, or general-purpose counters, the SN74LV161APWT from Texas Instruments provides designers with a reliable and efficient solution for their counting and timing needs. Its combination of low power consumption, high-speed operation, and robust feature set makes it a versatile choice for a wide array of applications.
