MC74VHCT574ADW

Flip Flops Overview

The MC74VHCT574ADW is an octal D-type flip-flop manufactured by onsemi using advanced LOG CMOS technology. It features eight D-type edge-triggered flip-flops with a single data output line per bit, providing non-inverting outputs. The device operates within a supply voltage range of 2.0 V to 3.6 V and includes a clock enable input for controlling data latching. It is housed in a 20-lead SOIC package.

Flip Flops Feature Summary

• Utilizes LOG CMOS technology for high-speed operation and low power consumption
• Contains eight independent D-type edge-triggered flip-flops
• Features a clock enable input to control data latching timing
• Provides non-inverting outputs for direct signal interfacing

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Buffering and register applications in digital systems
• Data storage elements in microprocessor-based designs

Flip Flops Procurement Notes

Verify the specific suffix 'DW' corresponds to the 20-SOIC package configuration as documented. Confirm that the LOG CMOS series specifications align with the target voltage requirements of 2.0 V to 3.6 V. Ensure compatibility with existing board layouts for the SOIC-20 footprint before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when high-speed logic performance is required at lower voltages compared to standard HCT or HC families. The LOG CMOS technology offers superior speed-power trade-offs suitable for battery-operated devices. Consider the single-ended output structure and the necessity of the clock enable feature for precise timing control in the design.

Flip Flops Part Context

This part belongs to the MC74VHCT574A family of octal D-type flip-flops. It is distinct from the MC74HCT574A series which uses HCT logic levels and typically operates at 5 V. The VHCT designation indicates the use of LOG CMOS technology, offering faster switching speeds and different input threshold characteristics compared to conventional CMOS logic families.
