74HC594D,118

Shift Registers Overview

The Nexperia 74HC594D,118 is an 8-bit serial-in/serial or parallel-out shift register with a storage register. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features synchronous serial input and output, independent clocks for shift and storage registers, and separate direct clear inputs. It provides push-pull outputs and includes clamp diodes on inputs to allow interfacing with voltages exceeding VCC using current limiting resistors.

Shift Registers Feature Summary

• Provides 8-bit parallel output capability via dedicated Q0 through Q7 pins
• Features independent clock and reset controls for both the shift and storage registers
• Includes a serial data output (Q7S) to enable cascading multiple devices

Shift Registers Applications

• Serial-to-parallel data conversion
• Remote control holding register

Shift Registers Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the base part number covers multiple variants. Confirm the logic family designation corresponds to the intended voltage levels. Ensure the temperature grade aligns with the operational environment requirements before finalizing procurement specifications.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with independent storage control is required. The wide supply voltage range allows flexibility in system design. Verify compatibility with CMOS input levels. Consider the SOIC-16 package dimensions for PCB layout constraints and thermal dissipation needs during the selection process.

Shift Registers Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices manufactured by Nexperia. It is functionally compatible with other 74HC594 variants but is specifically packaged in the SOIC-16 format designated by the 'D' suffix. The device adheres to JEDEC standards for operation and ESD protection.

Shift Registers Replacement Considerations

Cross-reference with other 74HC594 variants from different manufacturers if pinout compatibility is required. Verify that alternative packages match the physical footprint constraints of the existing design.
