74AHC574BQ,115

Overview

The Nexperia 74AHC574BQ,115 is a CMOS D-type edge-triggered flip-flop featuring eight non-inverting outputs. It operates within a supply voltage range of 2 V to 5.5 V and supports a maximum clock frequency of 200 MHz. The device exhibits a propagation delay of 16.7 ns and provides output drive currents of ±8 mA. Packaged in a 20-DHVQFN (4.5x2.5 mm) surface-mount housing with exposed pad, it functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides eight parallel data storage channels via positive-edge triggered D-type flip-flops
• Features high-speed operation with a maximum clock frequency of 200 MHz
• Delivers strong output drive capability with ±8 mA current sourcing and sinking

Applications

• Parallel-to-serial and serial-to-parallel data conversion circuits
• Register banks for temporary data storage in digital systems
• Interface buffering between microcontrollers and peripheral devices

Procurement Notes

Verify the specific suffix '115' corresponds to the DHVQFN-20 package variant during procurement. Confirm that the application environment remains within the specified -40°C to +85°C operating temperature limits. Ensure power supply decoupling is adequate for the 2 V to 5.5 V operating range to maintain signal integrity at high frequencies.

Selection Notes

Select this component when a compact surface-mount solution is required for eight-bit data latching. The DHVQFN package offers space efficiency compared to standard SOIC or TSSOP alternatives. Consider the ±8 mA drive strength for direct interfacing with moderate capacitive loads without additional buffer stages.

Part Context

This part belongs to the 74AHC logic family, designed for low-power CMOS applications with speeds comparable to TTL. The 'BQ' designation indicates the specific DHVQFN package type, while '115' denotes the reel quantity and tape configuration. It serves as a digital storage element within broader logic subsystems.

Replacement Considerations

The 74AHC574D,118 offers identical logical functionality but utilizes an SOIC-20 package. The 74AHC574PW,118 provides the same circuit in a TSSOP-20 housing. Verify pin compatibility and thermal requirements when substituting these package variants.
