MM74HC594M

Shift Registers Overview

The MM74HC594M is an 8-bit serial-in, parallel-out shift register with output registers manufactured by onsemi. It utilizes advanced silicon-gate CMOS technology and operates within a supply voltage range of 2V to 6V. The device features separate clocks for the shift register and storage register, along with direct overriding clears. It supports cascading via a serial output pin and guarantees a shift frequency up to 30 MHz at 4.5V. The component is housed in a 16-lead Small Outline Integrated Circuit (SOIC) package.

Shift Registers Feature Summary

• Contains an 8-bit serial-in, parallel-out shift register feeding an 8-bit D-type storage register
• Features separate positive-edge triggered clocks and direct overriding clears for both registers
• Capable of driving 15 LS-TTL loads with high noise immunity and low power consumption

Shift Registers Applications

• Data acquisition systems requiring serial-to-parallel conversion
• LED display drivers utilizing cascaded configurations
• Industrial control interfaces needing I/O expansion

Shift Registers Procurement Notes

Verify the specific ordering suffix to confirm the package type, as the MM74HC594 series includes both SOIC and PDIP variants. Ensure the selected version matches the required footprint and lead configuration for the target PCB design. Confirm RoHS compliance status if environmental regulations apply to the manufacturing process.

Shift Registers Selection Notes

Select this component when a combined shift and storage function is required in a single IC. It is suitable for applications demanding compatibility with standard 74LS logic families while benefiting from CMOS characteristics. Consider the separate clock inputs if independent control over data shifting and latching is necessary for the system timing.

Shift Registers Part Context

This part belongs to the MM74HC594 family of 8-bit shift registers with output latches. It is functionally compatible with the standard 74LS logic family regarding speed and pin-out. The device is designed for general-purpose digital logic applications where reliable serial data processing and parallel output are essential requirements.

Shift Registers Replacement Considerations

Check datasheets for other 8-bit shift registers with latches to ensure pinout and electrical specifications match. Verify that alternative components support the same operating voltage range and drive capabilities.
