74HC594DB,112

Shift Registers Overview

The Nexperia 74HC594DB,112 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 separate clock and reset inputs for both the shift and storage registers. Data shifts on LOW-to-HIGH transitions of the SHCP input, while transfer to the storage register occurs on STCP transitions. It includes a serial output (Q7S) for cascading and clamp diodes on inputs.

Shift Registers Feature Summary

• Provides synchronous serial input and output capabilities with 8-bit parallel data availability.
• Features independent direct clear and clock controls for both the shift and storage registers.
• Includes a serial output pin to facilitate cascading multiple devices in series.
• Offers high noise immunity and low power dissipation characteristics typical of CMOS technology.

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm package type and temperature range. Ensure compatibility with system voltage levels and interface requirements before integration. Confirm current production status as product lifecycles may change. Cross-reference datasheet revision history for any functional updates.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with separate storage control is required. Verify that the operating voltage falls between 2.0 V and 6.0 V. Consider the SSOP16 package dimensions for PCB layout constraints. Ensure the application does not exceed the specified maximum frequency limits under the given load conditions.

Shift Registers Part Context

This part belongs to the 74HC logic family, designed for general-purpose digital applications. It is manufactured by Nexperia USA Inc. and utilizes a plastic shrink small outline package with 16 leads. The device complies with JEDEC standards for low-voltage CMOS logic families.

Shift Registers Replacement Considerations

Check for equivalent parts such as 74HC594D or 74HC594PW if package variations are acceptable. Verify pinout compatibility and electrical specifications before substitution.
