74LVX594TTR

Shift Registers Overview

The 74LVX594TTR is a low voltage CMOS 8-bit shift register with an output register, manufactured by STMicroelectronics in a TSSOP-16 package. It operates within a supply voltage range of 2V to 3.6V and features 5V tolerant inputs. The device includes separate clocks for the shift and storage registers, along with direct overriding clear inputs. It provides symmetrical output impedance with minimum drive currents of 4mA and balanced propagation delays.

Shift Registers Feature Summary

• Features power down protection on all inputs allowing operation with input voltages from 0 to 7V regardless of supply voltage.
• Includes static discharge protection circuits providing 2KV ESD immunity against transient excess voltage.
• Designed for high-speed performance combined with true CMOS low power consumption characteristics.

Shift Registers Applications

• Low power battery operated applications
• Low noise 3.3V system designs
• Interfacing 5V systems to 3V systems

Shift Registers Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm the specific TSSOP-16 packaging and RoHS compliance status prior to integration. Ensure that design parameters align with the absolute maximum ratings provided in the datasheet to prevent device damage during operation.

Shift Registers Selection Notes

Select this component when interfacing between 5V logic levels and 3.3V systems is required. Consider its 8-bit serial-to-parallel conversion capability and independent clocking for shift and storage registers. Evaluate the low power dissipation and high-speed performance metrics against system requirements.

Shift Registers Part Context

This part belongs to the 74LVX series of low voltage CMOS logic devices. It is functionally compatible with the standard 74 Series 594 but optimized for lower voltage operation. The TTR suffix indicates the tape and reel packaging format suitable for automated surface mount assembly processes.

Shift Registers Replacement Considerations

Check for pin-compatible alternatives within the same logic family if availability is constrained. Verify that any substitute maintains the 5V tolerant input specifications and operating voltage range of 2V to 3.6V.
