SN74HCS574RKSR

Flip Flops Overview

The SN74HCS574RKSR is an octal edge-triggered D-type flip-flop from Texas Instruments, belonging to the AHCT logic series. It integrates eight independent D-type flip-flops with a shared rising-edge triggered clock input and a low-active output enable input. The device features Schmitt trigger inputs for noise filtering and provides three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a VQFN-20 package.

Flip Flops Feature Summary

• Integrates eight D-type flip-flops with a common clock and output enable control
• Incorporates Schmitt trigger architecture on all inputs for enhanced noise immunity
• Provides three-state outputs for efficient bus-oriented system connections

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• Bus latch applications in digital systems

Flip Flops Procurement Notes

Verify that the specific suffix RKSR corresponds to the VQFN-20 package and reel packaging configuration as documented. Confirm compatibility with standard surface-mount assembly processes. Ensure the selected variant meets the required operating temperature range and electrical specifications for the target application environment before finalizing procurement.

Flip Flops Selection Notes

Select this component when a CMOS-compatible interface with TTL-level input thresholds is required for 5V logic systems. The HCS series offers improved noise margins compared to standard HC devices due to Schmitt triggers. Consider the VQFN-20 package for compact board layouts requiring small footprint solutions with adequate thermal performance.
