74LV595D/AUJ

Shift Registers Overview

The 74LV595 is an 8-bit serial-in/serial-out or parallel-out shift register with output latches and 3-state outputs. It operates on a wide supply voltage range from 1.0 V to 3.6 V. The device features separate clocks for the shift and storage registers, a direct clear input for the shift register, and an asynchronous master reset (MR) input. Data shifts on LOW-to-HIGH transitions of the SHCP input and transfers to the storage register on STCP transitions. Outputs assume a high-impedance OFF-state when the OE input is HIGH.

Shift Registers Feature Summary

• Wide supply voltage range from 1.0 V to 3.6 V
• Direct interface with TTL levels
• Low power CMOS dissipation
• High latch-up performance exceeding 100 mA per JESD 78 Class II Level B

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the specific package suffix against the ordering information table. The 'D' suffix indicates an SO16 plastic small outline package (SOT109-1), while 'PW' indicates a TSSOP16 package (SOT403-1). Confirm the temperature range requirement matches the -40 °C to +125 °C specification listed for these packages. Ensure the component source aligns with Nexperia manufacturing standards.

Shift Registers Selection Notes

Select this component for low-voltage applications requiring serial-to-parallel conversion. It supports direct interfacing with TTL logic levels between VCC = 2.7 V and VCC = 3.6 V. The device offers multiple package options including SO16 and TSSOP16. Consider the ESD protection capabilities, which exceed 2000 V HBM and 1000 V CDM, for robust designs.

Shift Registers Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices. It is functionally compatible with 74HC/HCT595 devices but optimized for lower voltage operation down to 1.0 V. The series complies with JEDEC standards for various voltage ranges, including JESD8-7, JESD8-5, and JESD8C.

Shift Registers Replacement Considerations

The 74LV595D/AUJ is not explicitly listed in the provided datasheet as having a direct substitute. However, the base 74LV595 family is pin and function compatible with 74HC/HCT595 devices. Verify voltage compatibility when substituting with HC or HCT variants.
