74HC594DB,118

Shift Registers Overview

The Nexperia 74HC594DB,118 is an 8-bit serial-in/serial or parallel-out shift register with a storage register, housed in an SSOP16 package (SOT338-1). 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 separate clock and reset inputs for both the shift and storage registers, enabling independent control. It includes a serial output (Q7S) for cascading and input clamp diodes for interfacing with voltages exceeding VCC.

Shift Registers Feature Summary

• Provides synchronous serial data shifting and storage capabilities with independent clocks and direct clear functions for both registers.
• Features high noise immunity and robust latch-up performance that exceeds JESD 78 Class II Level B requirements.
• Includes ESD protection compliant with ANSI/ESDA/JEDEC standards, offering high tolerance against human body model and charged device model events.

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific ordering suffix '118' corresponds to the SSOP16 plastic shrink small outline package configuration. Confirm the component status as active production data sheet information before finalizing design implementation. Ensure compatibility with the specified operating temperature range and voltage limits during procurement validation.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with a dedicated storage register is required in a compact SSOP16 footprint. It is suitable for designs needing independent control over shift and storage operations via separate clock inputs. Verify that the CMOS logic level inputs meet the system's voltage requirements within the 2.0 V to 6.0 V operating range.

Shift Registers Part Context

This part belongs to the Nexperia 74HC/HCT594 family of 8-bit shift registers. The 'HC' designation indicates CMOS logic levels, while the 'DB' suffix specifies the SSOP16 package variant. It shares functional similarities with other members of the series but differs in package type and specific electrical characteristics defined by the HC technology node.

Shift Registers Replacement Considerations

Direct substitutes include other manufacturers' 74HC594 variants in SSOP16 packages. Verify pinout compatibility and electrical specifications such as propagation delay and supply voltage ranges before substitution.
