74LV74D,118

Overview

The Nexperia 74LV74D,118 is a dual positive-edge triggered D-type flip-flop housed in a 14-SOIC surface-mount package. It operates within a supply voltage range of 2.0 V to 5.5 V and supports data rates up to 200 MHz. The device features asynchronous set and reset inputs with active-low logic levels. Electrical specifications include a maximum propagation delay of 6.5 ns at 3.3 V and output drive capabilities of 24 mA for both high and low states. It complies with JEDEC standards JESD8-C and JESD8-2B for 2.7 V to 5.5 V operation.

Feature Summary

• Dual D-type flip-flops with complementary outputs
• Asynchronous active-low set and reset controls
• Positive-edge clock triggering mechanism
• 5 V tolerant input structure

Applications

• Parallel-to-serial data conversion circuits
• Shift register construction
• Timing delay element implementation
• General-purpose digital storage applications

Procurement Notes

Verify the specific suffix '118' corresponds to the SOIC-14 tape-and-reel packaging configuration required for automated assembly processes. Confirm that the operating voltage range aligns with the target system's power rails, as the device supports both 3.3 V and 5 V logic levels. Ensure ESD handling protocols are followed during component placement due to CMOS sensitivity.

Selection Notes

Select this component when a dual flip-flop solution is required for synchronous data path management. The wide supply voltage compatibility allows integration into mixed-voltage systems without additional level shifting. Consider the 14-pin SOIC footprint for PCB layout constraints and verify that the 200 MHz speed rating meets the system clock frequency requirements.

Part Context

This part belongs to the Nexperia 74LV series, which utilizes Low-Voltage CMOS technology to balance performance with power efficiency. The 74LV74 variant specifically provides two independent D-type flip-flops in a single package, offering a compact alternative to discrete logic solutions for sequential circuit design.

Replacement Considerations

The SN74LV74AD from Texas Instruments serves as a confirmed functional substitute with identical logical operations and pinout compatibility.
