74HC597PW,118

Overview

The Nexperia 74HC597PW,118 is an 8-bit shift register with input flip-flops housed in a TSSOP16 package. It features a wide supply voltage range from 2.0 V to 6.0 V and operates within a temperature range of -40 °C to +125 °C. The device includes positive edge-triggered clocks for both storage and shift registers, along with direct load and clear inputs. Static characteristics specify low power dissipation typical of CMOS technology.

Feature Summary

• Comprises an 8-bit storage register feeding a parallel-in, serial-out shift register
• Includes input flip-flops with positive edge-triggered clocking
• Features clamp diodes on inputs for interfacing with voltages exceeding VCC
• Provides asynchronous master reset and parallel load capabilities

Applications

• Serial-to-parallel data conversion circuits
• Parallel-to-serial data transmission systems
• Digital display driver interfaces
• Memory expansion architectures

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product status documentation. Confirm that the TSSOP16 package variant matches the required board layout specifications. Ensure compliance with RoHS directives and check for any recent production change notices affecting this part number before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring simultaneous parallel loading and serial shifting operations. The inclusion of input flip-flops allows for glitch-free data capture independent of the shift clock. Verify that the operating voltage remains within the specified 2.0 V to 6.0 V range to maintain signal integrity and noise immunity standards defined in the datasheet.

Part Context

This component belongs to the 74HC logic family, characterized by high-speed CMOS operation and compatibility with standard TTL input levels at higher supply voltages. The PW suffix denotes the plastic thin shrink small outline package with 16 leads. It serves as a fundamental building block for sequential logic applications requiring data serialization or deserialization functions.

Replacement Considerations

Direct substitutes include other manufacturers' 74HC597 variants in compatible packages. Cross-reference pinouts and electrical specifications carefully. Ensure replacement parts meet the same temperature range and ESD protection requirements specified for the original design.
