74LVC594APW,112

Shift Registers Overview

The Nexperia 74LVC594APW,112 is an 8-bit serial-in/serial or parallel-out shift register with a storage register. It operates on a wide supply voltage range from 1.2 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device includes separate clock and reset inputs for both the shift and storage registers, allowing independent control. It supports cascading via a serial output (Q7S) and incorporates IOFF circuitry for partial power-down applications. All inputs feature Schmitt-trigger action to tolerate slower rise and fall times.

Shift Registers Feature Summary

• Provides serial-to-parallel data conversion capabilities with independent shift and storage register clocks.
• Features IOFF circuitry that disables outputs during partial power-down to prevent damaging backflow currents.
• Includes Schmitt-trigger action at all inputs to ensure tolerance of slower input signal transitions.

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. Confirm current product status as availability may vary by region. Ensure compatibility with mixed 3.3 V and 5 V environments if interfacing with different logic families. Check for any recent Product Change Notices regarding manufacturing transfers or specification updates.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with tri-state outputs is required in a low-voltage CMOS environment. It is suitable for designs needing direct interface with TTL levels and operation across a wide temperature range. Consider the TSSOP16 package constraints for board space. Verify that the input voltage requirements align with the system's logic levels, noting the 5.5 V tolerance.

Shift Registers Part Context

This part belongs to the 74LVC594A family of 8-bit shift registers manufactured by Nexperia. It is designed for use in mixed 3.3 V and 5 V environments due to its overvoltage tolerant inputs. The device is specified for industrial temperature ranges and complies with JEDEC standards for low-power CMOS logic devices.
