The SN74ALS166NSR is a de-register type 8−bit bidirectional shift register. It is part of a wide family of registers that are typically used in a variety of applications including data processing, data encoding, and data formatting. The SN74ALS166NSR is a logic shift register designed to be used in applications that require the bitwise shifting of data, either unshift or shift.
Device Overview
The SN74ALS166NSR is a de-register type 8-bit bidirectional shift register. It is a CMOS logic device featuring non-inverting, bidirectional data transfer. Data is clocked into the device on a rising edge of the clock and can be output either in the same direction as it was clocked in or in the opposite direction.The device can also be used in applications that require bitwise shifting. In the SN74ALS166NSR, data can be shifted in both the unshift and shift modes, depending on the value of the "shift" signal. If the shift signal is high, then data is shifted out of the device from the QA output in the direction of the shift signal. If the shift signal is low, then data is shifted in the opposite direction.The device features a low power shutdown mode that can be enabled by the shift signal, allowing the device to be powered down when not in use.The SN74ALS166NSR is a highly versatile shift register and can be used in a variety of applications, such as in a data processor, where data needs to be shifted in order to format and process it, in data encoding, where data needs to be shifted in order to encode it, and in data formatting, where data needs to be shifted in order to properly format it for transmission or display.
Working Principle
The SN74ALS166NSR works by shifting data in the direction of the shift signal in either the unshift or shift mode, depending on the value of the shift signal. Data is clocked into the device on a rising edge of the clock and can be output either in the same direction as it was clocked in or in the opposite direction. The device features two 8-bit data registers and two 8-bit control registers. The control registers are used to control how the data is shifted and how the device operates.The "unshift" register is used to control the direction of data transfer. When the unshift register is enabled, the data will be shifted out of the device in the opposite direction to that of the shift signal.The "shift" register is used to control the direction of data transfer. When the shift register is enabled, the data will be shifted out of the device in the same direction as the shift signal.The "enable" register is used to enable or disable the device. When the enable register is enabled, the device will be active and will be able to receive data from the clock and shift it in the direction of the shift signal. When the enable register is disabled, the device will be inactive and data will not be shifted. The "power down" register is used to enable or disable the low power shutdown mode of the device. When the power down register is enabled, the device will be powered down when not in use, allowing the device to save power.Conclusion
The SN74ALS166NSR is a de-register type 8-bit bidirectional shift register that can be used in a variety of applications. It is an extremely versatile device that can be used for data processing, data encoding, and data formatting. The device features two 8-bit data registers and two 8-bit control registers. Data is clocked into the device on a rising edge of the clock and can be output either in the same direction as it was clocked in or in the opposite direction. The device also features a low power shutdown mode that can be enabled by the shift signal, allowing the device to be powered down when not in use.The specific data is subject to PDF, and the above content is for reference
