MM74HC589MX

Shift Registers Overview

The MM74HC589MX is an 8-bit shift register with input latches and 3-state serial output, manufactured by onsemi. It utilizes advanced silicon-gate CMOS technology for high noise immunity and low power consumption. The device features a wide operating voltage range of 2V to 6V and can drive 15 LS-TTL loads. It includes a parallel storage register feeding a parallel-in, serial-out shift register, with positive-edge triggered clocks for both registers. The component supports guaranteed shift frequencies up to 30 MHz at 5V supply.

Shift Registers Feature Summary

• Features an 8-bit parallel storage register that feeds data into an 8-bit shift register.
• Provides a 3-state serial output to enable wire-ORing of multiple devices on a bus.
• Supports direct overriding load for the shift register via the SLOAD pin.
• Utilizes silicon-gate CMOS technology for high noise immunity and low quiescent current.

Shift Registers Applications

• Bus-oriented systems requiring serial data transmission
• Parallel-to-serial data conversion interfaces
• Digital logic circuits utilizing 3-state bus architectures

Shift Registers Procurement Notes

Verify the specific package type and suffix requirements against the official datasheet before ordering. Confirm that the MM74HC589MX designation aligns with the required 16-Lead Small Outline Integrated Circuit (SOIC) form factor. Ensure compatibility with the intended operating voltage range and temperature specifications for the target application environment.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with input latching and 3-state outputs is required. It is suitable for applications needing direct interface with TTL loads while maintaining CMOS performance characteristics. Consider the guaranteed shift frequency and propagation delay limits relative to the system clock speed and load capacitance constraints.

Shift Registers Part Context
