M74HC4094YTTR

Shift Registers Overview

The M74HC4094YTTR is a high-speed CMOS 8-bit serial-in parallel-out (SIPO) shift latch register manufactured by STMicroelectronics. It integrates an 8-bit shift register and an 8-bit latch with a 3-state output buffer, fabricated using silicon gate C2MOS technology. The device operates within a wide voltage range of 2 V to 6 V and supports a maximum frequency of 80 MHz at 6 V. It features symmetrical output impedance, balanced propagation delays, and high noise immunity. The component is housed in a TSSOP-16 package and is qualified under AEC-Q100 standards for automotive applications.

Shift Registers Feature Summary

• Integrates an 8-bit shift register and an 8-bit latch with a 3-state output buffer for efficient data handling.
• Features high-speed operation with a typical maximum frequency of 80 MHz at 6 V supply voltage.
• Includes protection circuits against static discharge and transient excess voltage on all inputs.
• Offers pin and function compatibility with the standard 74 series 4094 devices.

Shift Registers Applications

• Automotive electronic systems requiring AEC-Q100 qualified logic components
• Serial-to-parallel data conversion in digital communication interfaces
• Cascaded shift register configurations for expanded I/O control

Shift Registers Procurement Notes

Verify the specific ordering suffix matches the required tape and reel configuration for automated assembly. Confirm that the TSSOP-16 package variant aligns with your PCB footprint requirements. Ensure the AEC-Q100 qualification status meets your automotive reliability standards. Cross-reference the datasheet revision to confirm electrical characteristics match your design specifications before finalizing procurement.

Shift Registers Selection Notes

Select this component when a high-speed, low-power 8-bit SIPO shift register with latching capability is required. The wide operating voltage range from 2 V to 6 V provides flexibility for various power supply designs. The 3-state output buffer allows for direct connection to bus structures without external tri-state buffers. Consider the AEC-Q100 qualification if the application demands automotive-grade reliability and temperature stability.

Shift Registers Part Context

This part belongs to the M74HC4094 family of high-speed CMOS logic devices. It is designed to replace or be compatible with the industry-standard 74HC4094. The device is part of STMicroelectronics' broader portfolio of CMOS logic ICs, offering robust performance for general-purpose digital logic applications in consumer, industrial, and automotive sectors.

Shift Registers Replacement Considerations

The M74HC4094YTTR is pin and function compatible with the standard 74HC4094. Verify that alternative sources offer equivalent AEC-Q100 qualification if automotive use is intended. Ensure the replacement maintains the same TSSOP-16 package and 3-state output buffer characteristics.
