SN74HC595N

Shift Registers Overview

The SN74HC595N is an 8-bit serial-in, serial or parallel-out shift register manufactured by Texas Instruments. It features a serial input and a serial or parallel output with three-state outputs for effective driving of bus lines. The device operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -40°C to +85°C. Propagation delays are specified at 200 ns, 40 ns, and 34 ns depending on conditions. It is housed in a PDIP-16 package.

Shift Registers Feature Summary

• Provides serial-to-parallel data conversion capabilities for expanding I/O ports.
• Features three-state outputs to facilitate connection to system buses without interference.
• Operates reliably across a broad industrial temperature range and standard CMOS logic levels.

Shift Registers Applications

• LED display matrix scanning and control systems
• Industrial process control I/O expansion
• Consumer electronics peripheral interfacing

Shift Registers Procurement Notes

Verify the specific suffix 'N' indicates the PDIP-16 through-hole package variant when sourcing. Confirm RoHS compliance status via the manufacturer's official documentation, as environmental declarations may vary by production batch. Ensure the ordering part number matches the required pin configuration and package style for your PCB layout.

Shift Registers Selection Notes

Select this component when a single-channel 8-bit shift register with tri-state outputs is required. The HC series offers compatibility with standard 5V and lower voltage logic families. Consider the PDIP-16 package constraints for manual assembly or prototyping environments where surface mount options are not preferred.

Shift Registers Part Context

This part belongs to the SN74HC595 family of high-speed CMOS logic devices. It serves as a fundamental building block for digital systems requiring data serialization and parallel output distribution. The device is widely used in legacy and modern designs alike due to its standardized interface and robust performance characteristics.

Shift Registers Replacement Considerations

Direct functional equivalents include the CD74HC595 and SN74HC595 (without suffix) which share identical logical operations. Verify package compatibility when substituting, as the 'N' suffix specifically denotes the DIP format. Other variants like SN74HCT595 offer TTL-compatible inputs but require different voltage considerations.
