74ALVC74BQ,115

Overview

The 74ALVC74BQ,115 is a dual D-type flip-flop manufactured by Nexperia USA Inc. It operates within a supply voltage range of 1.65 V to 3.6 V and supports a maximum clock frequency of 200 MHz. The device features positive-edge triggering with asynchronous set and reset inputs. Propagation delay is specified at 2.1 ns under typical conditions (3.3 V, 50 pF load). Output drive capability provides 24 mA for both high and low states. It is housed in a 14-DHVQFN package with dimensions of 2.5x3 mm, suitable for surface mount applications across an operating temperature range of -40°C to +85°C.

• Schmitt trigger action on all inputs for noise tolerance

Applications

• Parallel data storage and buffering
• Shift register construction
• Timing and synchronization circuits
• State machine implementation

Procurement Notes

Verify the specific suffix 'BQ' corresponds to the DHVQFN-14 package variant when sourcing. Confirm that the manufacturer's standard lead time aligns with project schedules, as this component typically follows a defined production cycle. Ensure compatibility with RoHS3 compliance requirements if applicable to the target assembly process. Cross-reference distributor part numbers such as 1727-6949-2-ND for accurate ordering identification.

Selection Notes

Select this component when a dual D-type flip-flop with high-speed performance is required. The 200 MHz clock frequency and 2.1 ns propagation delay make it suitable for fast digital logic applications. Consider the 1.65 V to 3.6 V supply range for compatibility with low-voltage systems. The DHVQFN package offers a compact footprint for space-constrained designs compared to larger QFP or SOIC alternatives.

Part Context

This part belongs to the 74ALVC series, which represents advanced low-voltage CMOS technology. It is functionally similar to other 74LVC variants but offers faster switching speeds. The 'BQ' suffix denotes the specific tape and reel packaging and the DHVQFN form factor. It serves as a fundamental building block for sequential logic circuits in modern embedded systems and consumer electronics.

Replacement Considerations

The 74LVC74A series offers comparable functionality with slightly different electrical characteristics. Other manufacturers may provide pin-compatible alternatives within the same logic family. Verify that any substitute maintains the same voltage range and package dimensions to ensure seamless integration into existing PCB layouts.
