M74HC165RM13TR

Shift Registers Overview

The M74HC165RM13TR is an 8-bit parallel-in serial-out (PISO) shift register from the STMicroelectronics 74HC series. It features a supply voltage range of 2V to 6V and operates within a temperature range of -55°C to 125°C. The device provides symmetrical output impedance with minimum drive currents of 4mA for both high and low states. Propagation delay from clock to output ranges from 15ns to 45ns depending on voltage, while maximum clock frequency reaches up to 71MHz at 6V.

Shift Registers Feature Summary

• Provides eight clocked master-slave RS flip-flops configured as a shift register with asynchronous parallel entry capability.
• Features dual clock inputs that function identically, allowing one input to serve as a clock inhibit signal via an internal NOR gate structure.
• Includes protection circuits on all inputs designed to guard against static discharge and transient excess voltage events.

Shift Registers Applications

• Parallel-to-serial data conversion in digital communication interfaces
• Expansion of microprocessor I/O ports using serial shifting techniques
• Digital logic circuits requiring temporary storage or sequencing of binary data

Shift Registers Procurement Notes

Verify the specific package type matches the design requirements, as the RM13 suffix indicates SOP packaging. Confirm the component status, as availability may vary across distributors. Ensure the operating environment stays within the specified electrical limits and temperature ranges defined in the datasheet before finalizing procurement decisions.

Shift Registers Selection Notes

Select this component when an 8-bit PISO configuration is required within the standard 74HC logic family specifications. Consider the wide operating voltage range and high noise immunity characteristics for robust performance in varying power conditions. Evaluate the propagation delays and maximum clock frequencies to ensure timing compatibility with the system's processing speed.
