CD74HC165MT

Shift Registers Overview

The CD74HC165MT is an 8-bit parallel-in/serial-out shift register manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and supports a wide operating temperature range from -55°C to +125°C. The device features push-pull outputs and is housed in a 16-SOIC package with a width of 3.90mm. It functions as a high-speed CMOS logic component designed for parallel-to-serial data conversion.

Shift Registers Feature Summary

• Provides eight-bit parallel loading capability for simultaneous data entry into internal registers.
• Converts parallel input data into serial output streams via dedicated Q7 and complementary pin.
• Supports clock inhibition functionality allowing flexible timing control during shifting operations.

Shift Registers Applications

• Input expansion for microcontroller systems requiring additional digital inputs.
• Keyboard scanning matrices for detecting multiple key presses simultaneously.
• Data acquisition systems converting parallel sensor signals to serial formats.

Shift Registers Procurement Notes

Verify the specific suffix MT indicates the SOIC-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the component meets the required industrial temperature specifications if deployed in harsh environments. Cross-reference ordering part numbers with current Texas Instruments product selection guides to avoid obsolete variants.

Shift Registers Selection Notes

Select this component when an 8-bit parallel load shift register is required with push-pull output drivers. Consider the 16-SOIC package constraints for PCB layout and thermal management. Evaluate the 2V to 6V operating voltage range against system power supplies. Verify compatibility with existing logic families regarding noise margins and propagation delays.
