CD74HCT166M

Shift Registers Overview

The CD74HCT166M is an 8-bit parallel-in serial-out shift register manufactured by Texas Instruments. It belongs to the HCT logic series, utilizing CMOS technology for operation. The device features a single circuit configuration with push-pull outputs and operates within a supply voltage range of 4.5 V to 5.5 V. It supports a minimum operating temperature of -55°C and a maximum of +125°C. The component is housed in a 16-SOIC surface-mount package with a width of 3.90 mm. Propagation delay is specified at 40 ns under standard conditions.

Shift Registers Feature Summary

• Supports parallel-to-serial data conversion functionality
• Features push-pull output drivers for signal integrity
• Compatible with standard TTL logic levels via HCT series design

Shift Registers Applications

• Data acquisition systems requiring parallel input buffering
• Serial communication interface modules
• Digital control circuits needing state storage

Shift Registers Procurement Notes

Verify the specific suffix 'M' corresponds to the SOIC-16 surface-mount package variant when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure the supplier provides official datasheets matching the Texas Instruments part number to guarantee electrical parameter accuracy and operational reliability.

Shift Registers Selection Notes

Select this component for applications requiring robust parallel data capture with serial output capabilities in harsh thermal environments. The HCT series compatibility ensures direct interfacing with standard logic families without additional level shifting. Consider the SOIC-16 footprint constraints during PCB layout planning to ensure adequate spacing and thermal management for high-temperature operation.

Shift Registers Part Context

This component is part of the broader 74HCT166 family of shift registers produced by Texas Instruments. It shares functional similarities with other members like the CD74HCT166E but differs in packaging format. The M suffix specifically denotes the surface-mount SOIC variant, distinguishing it from through-hole options while maintaining identical logical operations and electrical characteristics defined by the HCT standard.
