MM74HC597N

Shift Registers Overview

The MM74HC597N is an 8-bit shift register with input latches manufactured by onsemi (formerly Fairchild Semiconductor). It utilizes advanced silicon-gate CMOS technology and operates within a supply voltage range of 2V to 6V. The device features a guaranteed shift frequency of DC to 30 MHz, low quiescent current of 80 µA maximum, and the ability to drive 10 LS-TTL loads. It is housed in a 16-lead Plastic Dual-In-Line Package (PDIP) with a width of 0.300 inches.

Shift Registers Feature Summary

• Consists of an 8-bit storage latch feeding a parallel-in, serial-out 8-bit shift register with positive-edge triggered clocks for both registers.
• Features direct overriding load and clear inputs for the shift register, allowing immediate data transfer or reset independent of the clock edge.
• Provides high noise immunity and low power consumption typical of standard CMOS integrated circuits while maintaining compatibility with LS-TTL loads.

Shift Registers Applications

• Digital systems requiring serial-to-parallel data conversion
• Parallel-in, serial-out data transmission interfaces
• General-purpose 8-bit storage and shifting operations

Shift Registers Procurement Notes

Verify the package type matches the required DIP configuration, as this part number specifically denotes the 16-lead Plastic Dual-In-Line Package. Confirm that the operating environment stays within the specified temperature range of -40°C to +85°C for standard operation. Ensure supply voltage remains between 2V and 6V to maintain performance specifications. Check for any specific handling requirements related to static discharge protection provided by internal diode clamps.

Shift Registers Selection Notes

Select this component when a parallel-in, serial-out architecture with dedicated input latching is required. It is suitable for designs needing compatibility with the 74LS logic family in terms of speed, function, and pinout. Consider its low quiescent current and wide operating voltage range for applications where power efficiency and voltage flexibility are priorities. Ensure the design can accommodate the PDIP package dimensions if space constraints exist.

Shift Registers Part Context

This component belongs to the 74HC logic family, which offers speed, function, and pin-out compatibility with the standard 74LS logic family. It is designed using advanced silicon-gate CMOS technology to achieve high noise immunity and low power consumption. The device integrates an 8-bit storage latch and an 8-bit shift register, providing versatile data handling capabilities for digital circuit applications.

Shift Registers Replacement Considerations

Devices available in Tape and Reel format can be identified by appending the suffix letter 'X' to the ordering code. Other package options include the 16-Lead Small Outline Integrated Circuit (SOIC) and the 16-Lead Small Outline Package (SOP).
