74ALVC74D,112

Overview

The 74ALVC74D,112 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 utilizes a 14-SOIC package with a width of 0.154 inches (3.90 mm). The device features positive-edge triggering and includes asynchronous set and reset inputs. It supports a maximum clock frequency of 425 MHz and exhibits a propagation delay of 3.8 ns at 3.3 V with 50 pF load. Output drive capability is specified at 24 mA for both high and low states, with a static current consumption of 10 µA.

Feature Summary

• Dual D-type flip-flops with positive-edge triggering mechanism
• Asynchronous active-low set and reset inputs operating independently of the clock
• Complementary nQ and Q outputs for flexible logic interfacing

Applications

• High-speed data storage and transfer in digital systems
• Shift register implementations requiring fast clock frequencies
• Synchronization circuits for asynchronous signal crossing

Procurement Notes

Verify component authenticity through authorized Nexperia distributors or certified partners. Confirm RoHS3 compliance and MSL rating of 1 during incoming inspection. Ensure ESD handling protocols are strictly followed due to CMOS sensitivity. Validate packaging integrity against moisture damage risks despite the infinite shelf life classification under standard conditions.

Selection Notes

Select this component when designing low-voltage logic systems requiring high-speed performance up to 425 MHz. The 1.65 V to 3.6 V supply range ensures compatibility with modern portable and battery-operated devices. Consider the 14-SOIC package for surface-mount assembly constraints. Verify that the 24 mA output drive meets the fan-out requirements of the connected load circuitry without additional buffering.
