TC74HC165AP(F)

Overview

The TC74HC165AP(F) is an 8-bit parallel-load serial-in/serial-out shift register manufactured by Toshiba Semiconductor and Storage. It operates within a supply voltage range of 2.0 to 6.0 V and features a propagation delay of 15 ns with a drive current capability of 4 mA. The device belongs to the HC logic series and is designed for CMOS applications. It supports asynchronous parallel data loading when the parallel load input is low, while serial data enters through the DS pin on clock rising edges. The component is available in tube packaging.

Feature Summary

• Asynchronous parallel data loading capability allows immediate capture of input states without clock dependency.
• Serial output provides complementary signals at Q7 and Q7 bar for flexible interfacing.
• Gated clock structure enables independent control via CP and CE pins for simplified circuit routing.

Applications

• Parallel-to-serial data conversion in digital systems
• Expansion of I/O ports using cascaded configurations
• Key matrix scanning interfaces

Procurement Notes

Verify the specific suffix designation against official Toshiba documentation to confirm package type and tape/reel specifications. Ensure compatibility with system voltage levels between 2.0 V and 6.0 V. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement orders.

Selection Notes

Select this component for designs requiring reliable 8-bit parallel data acquisition with minimal pin count. The HC series offers standard CMOS performance suitable for general-purpose logic applications. Consider the 15 ns propagation delay for timing constraints in high-speed serial communication links.

Part Context

This part belongs to the Toshiba TC74HC165 family of 8-bit shift registers. It is functionally compatible with industry-standard 74HC165 devices. The AP(F) designation typically indicates a specific package variant, often a plastic DIP or similar through-hole configuration, distributed by authorized channels.

Replacement Considerations

Compatible substitutes include generic 74HC165 equivalents from other manufacturers. Verify pinout compatibility and electrical characteristics such as supply voltage range and output drive current before substitution.
