SN74ALS166NS

Shift Registers Overview

The SN74ALS166NS is a parallel-load, 8-bit serial-in/serial-out shift register manufactured by Texas Instruments. It belongs to the ALS logic family and utilizes bipolar technology. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 14 ns. It features nine input lines and is housed in a SOIC-16 package. The component functions as a single circuit with a maximum operating temperature of +70°C.

Shift Registers Feature Summary

• Parallel-load capability for simultaneous data entry into all eight bits
• Serial output functionality for sequential data transmission
• Bipolar ALS logic construction for defined switching characteristics

Shift Registers Applications

• Data storage and buffering in digital systems
• Serial-to-parallel conversion interfaces
• Pulse width modulation signal generation

Shift Registers Procurement Notes

Verify the specific suffix 'NS' confirms the SOIC-16 surface-mount package variant. Confirm the manufacturer designation aligns with Texas Instruments specifications. Ensure the logic family matches ALS requirements for your design. Check RoHS compliance status against current regulatory standards. Validate pinout compatibility with existing PCB footprints before integration.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with parallel load functionality is required. The ALS series offers faster switching speeds compared to standard LS logic. The SOIC-16 package suits surface-mount assembly processes. Verify that the 5V supply voltage range meets system power constraints. Consider the bipolar technology implications for noise immunity and drive strength.
