74HC299PW,118

Shift Registers Overview

The 74HC299PW,118 is an 8-bit universal shift register manufactured by Nexperia USA Inc. It features multiplexed inputs and outputs to improve bit density and supports four operating modes: shift left, shift right, hold, and load data. The device utilizes 3-state outputs for direct bus line driving and is cascadable for n-bit word lengths. It operates within a supply voltage range of 2V to 6V and functions across a temperature range of -40°C to +125°C.

Shift Registers Feature Summary

• Multiplexed input/output structure enhances bit density
• Supports shift left, shift right, hold, and load data modes
• 3-state outputs enable direct connection to bus lines
• Cascadable architecture allows expansion for n-bit word lengths

Shift Registers Applications

• Universal shift register circuits requiring bidirectional data movement
• Bus interface designs utilizing 3-state output control
• Data storage and transfer applications in digital systems
• Cascaded logic configurations for extended word length processing

Shift Registers Procurement Notes

Verify the specific suffix '118' corresponds to the TSSOP-20 package variant when sourcing. Confirm RoHS compliance status as per current manufacturer documentation. Check for any Product Change Notifications (PCN) regarding assembly or labeling updates that may affect part marking or packaging specifications prior to final procurement decisions.

Shift Registers Selection Notes

Select this component for applications requiring an 8-bit universal shift register with high-speed CMOS performance. Ensure the design accommodates the 2V to 6V supply voltage range. Verify that the TSSOP-20 package dimensions fit the PCB layout constraints. Consider the ESD protection levels if the application involves handling sensitive signals without adequate shielding.

Shift Registers Part Context

This part belongs to the 74HC series of high-speed Si-gate CMOS devices. It is pin-compatible with Low-power Schottky TTL (LSTTL) devices, facilitating easier upgrades from legacy logic families. The device is specified in compliance with JEDEC standard no. 7A, ensuring interoperability with other industry-standard components.

Shift Registers Replacement Considerations

The 74HC299D is a documented alternative variant from the same manufacturer family. Verify package compatibility and electrical specifications before substitution. Cross-reference with other 8-bit universal shift registers if the specific Nexperia part is unavailable.
