M74HC595YTTR

Shift Registers Overview

The M74HC595YTTR is an 8-bit serial-in, parallel-out shift register with output latches and 3-state outputs, manufactured by STMicroelectronics. It belongs to the HC logic series using CMOS technology. The device operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 59 MHz at 6 V. Propagation delay is typically 45 ns. It features a direct overriding clear, separate clocks for shift and storage registers, and positive edge triggering. The component is qualified under AEC-Q100 standards for automotive applications and operates between -40°C and +125°C. It is housed in a 16-TSSOP surface-mount package.

Shift Registers Feature Summary

• Provides 8-bit serial-to-parallel conversion with independent shift and storage register clocks.
• Features 3-state parallel outputs capable of driving multiple loads with symmetrical impedance.
• Includes a direct overriding clear input for immediate reset of the shift register state.
• Built with high-speed CMOS technology ensuring low power dissipation and high noise immunity.

Shift Registers Applications

• Automotive electronic systems requiring AEC-Q100 qualified logic components
• Industrial control interfaces utilizing serial data expansion
• Consumer electronics employing LED display multiplexing or indicator arrays

Shift Registers Procurement Notes

Verify that the specific order matches the M74HC595YTTR designation to ensure the TSSOP-16 package and automotive qualification are present. Confirm that the required operating temperature range aligns with the specified -40°C to +125°C limits. Check for compliance with RoHS3 specifications if environmental regulations apply to the final assembly. Ensure handling procedures account for ESD sensitivity despite internal protection circuits.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with tri-state outputs is required in a space-constrained surface-mount design. The HC series compatibility ensures pinout and functional interchangeability with standard 74-series logic. Consider the AEC-Q100 qualification if the application demands automotive reliability standards. Evaluate the 2V to 6V supply range against system power constraints to ensure adequate noise margins and switching speeds.

Shift Registers Part Context

This part is a member of the M74HC595 family from STMicroelectronics, designed as a high-speed CMOS shift register. It serves as a digital logic interface component for converting serial data streams into parallel outputs. The device is distinct from other variants by its specific TSSOP-16 packaging and automotive-grade certification, differentiating it from industrial-grade counterparts like the M74HC595RM13TR which may lack AEC-Q100 qualification.
