74LVT74DB,112

Overview

The 74LVT74DB,112 is a dual positive-edge-triggered D-type flip-flop with set and clear inputs manufactured by NXP USA Inc. It operates within a supply voltage range of 2.7 V to 3.6 V and features three-state outputs. The device is housed in a 14-pin SSOP package (SOT337-1) designed for surface-mount applications. Key electrical characteristics include a propagation delay of 5.0 ns at 3.3 V and output drive capabilities of ±8 mA for both high and low states. It supports a wide operating temperature range from -40 °C to +85 °C and complies with JEDEC standards.

Feature Summary

• Dual D-type flip-flops with independent set and clear functions
• Positive-edge triggering for precise data capture
• Three-state outputs for bus-oriented system designs
• 3.3 V logic level compatibility with robust noise immunity

Applications

• Parallel-to-serial and serial-to-parallel data conversion circuits
• High-speed buffering and register stages in digital systems
• Timing control and synchronization logic modules
• Data storage elements in microprocessor-based architectures

Procurement Notes

Verify the specific ordering code suffix to confirm the SSOP-14 package variant. Confirm RoHS compliance status through official Nexperia documentation prior to integration. Check current production lifecycle status as components may be subject to discontinuation notices. Ensure supply chain sources provide valid traceability for quality assurance requirements.

Selection Notes

Select this component when designing 3.3 V logic systems requiring dual edge-triggered storage. Compare against 74HC or 74HCT series if lower voltage operation or different speed profiles are needed. Verify that the SSOP-14 footprint matches the target PCB layout constraints. Consider thermal performance within the specified -40 °C to +85 °C range for industrial environments.

Part Context

This part belongs to the 74LVT family of low-voltage CMOS logic devices. It shares functional similarities with other D-type flip-flops like the 74LVT75 but differs in pinout and configuration. The 74LVT series is optimized for 3.3 V applications, offering improved switching speeds compared to older 5 V logic families while maintaining compatibility with standard digital interfaces.

Replacement Considerations

Public confirmed substitutes include the 74LVT74D,652 and 74LVT74PW,112. Verify package compatibility between SO14 and SSOP14 variants before substitution. Cross-reference datasheet parameters to ensure equivalent timing and electrical characteristics.
