M74HC164RM13TR

Shift Registers Overview

The M74HC164RM13TR is an 8-bit serial-in parallel-out (SIPO) shift register from the STMicroelectronics HC logic family. It operates on a supply voltage range of 2V to 6V and utilizes silicon gate C2MOS technology. The device features two data inputs (A and B) that function as an AND gate for serial entry, with edge-triggered clocking on rising transitions. It includes an asynchronous master reset input that forces all outputs low when active. The component is housed in a 14-pin SOIC package.

Shift Registers Feature Summary

• Provides serial-to-parallel data conversion through eight independent output stages.
• Features dual data inputs that act as an enable gate for the primary data stream.
• Includes an asynchronous clear function that overrides clock and data inputs to reset outputs.

Shift Registers Applications

• Serial communication interface data buffering
• LED display matrix scanning drivers
• Parallel data expansion for microcontroller systems

Shift Registers Procurement Notes

Verify the specific ordering suffix RM13TR corresponds to the Tape & Reel packaging format for the SO-14 variant. Confirm the manufacturer part number matches the official STMicroelectronics datasheet documentation. Ensure compatibility with standard surface mount assembly processes for the specified package dimensions.

Shift Registers Selection Notes

Select this component for designs requiring high-speed CMOS performance with wide voltage flexibility. The HC series offers noise immunity and symmetrical output impedance suitable for general digital logic applications. Consider the asynchronous reset feature for system initialization requirements and verify operating temperature ranges against environmental conditions.

Shift Registers Part Context

This device belongs to the M74HC164 series of 8-bit SIPO shift registers. It is pin and function compatible with the standard 74164 logic family. The product line includes various package options such as DIP and TSSOP, with the RM13TR designation specifically indicating the surface-mount SOIC configuration.

Shift Registers Replacement Considerations

Direct substitutes include other manufacturers' 74HC164 variants in SO-14 packages. Verify electrical specifications and pinout compatibility before substitution. Cross-reference with equivalent parts from other logic families if voltage or speed requirements differ.
