74LV574PW,112

Overview

The NXP USA Inc. 74LV574PW,112 is an octal D-type flip-flop featuring positive edge triggering and three-state outputs. It belongs to the LV logic series, designed for low-voltage CMOS applications with a supply voltage range of 1 V to 5.5 V. The device operates within a temperature range of -40°C to +125°C and utilizes a 20-TSSOP surface-mount package. Key electrical parameters include a propagation delay of 13 ns at 3.3 V and 17 ns at 5 V with a 50 pF load. It supports output currents of ±16 mA and has a maximum clock frequency of 70 MHz.

Feature Summary

• Octal D-type flip-flop architecture with positive edge-triggered operation
• Three-state outputs providing non-inverting data transmission
• Wide operating voltage range supporting 1 V to 5.5 V systems
• Industrial-grade temperature capability from -40°C to +125°C

Applications

• Data storage in digital logic circuits
• Bus driver implementations requiring tri-state control
• Parallel-to-serial conversion interfaces
• Memory buffer stages in embedded systems

Procurement Notes

This component is officially listed as obsolete and no longer manufactured by Nexperia or NXP. Distributors indicate that the factory is not accepting orders, and current stock levels are zero or unavailable in many regions. Procurement requires verification of existing inventory sources or authorized surplus dealers, as new production units are not available. Designers should initiate replacement strategies immediately due to discontinuation status.

Selection Notes

Engineers selecting this part must account for its discontinued status and limited availability. The LV series offers lower power consumption compared to standard TTL but requires careful attention to the 1 V minimum supply voltage. When replacing, verify that the substitute component matches the 20-TSSOP footprint and maintains compatible timing characteristics, specifically the propagation delay and clock frequency limits under similar load conditions.

Part Context

The 74LV574PW,112 is part of the broader 74LV574 family, which includes variants like the 74LV574DB and 74LV574PWDH-T. These components share the same logical function as octal D-type flip-flops but may differ in packaging or specific electrical tolerances. The PW suffix denotes the TSSOP package type, while the ,112 indicates a specific tape-and-reel or tube configuration detail defined by the manufacturer's ordering code structure.
