74LVTH574DB,112

Overview

The SN74LVTH574DBR is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the LVTH logic series. It features a 20-SSOP package and operates within a supply voltage range of 2.7 V to 3.6 V. The device includes eight non-inverting circuits with three-state outputs and TTL-compatible inputs. Key electrical parameters include a propagation delay of 3 ns, a high-level output current of -32 mA, and a low-level output current of 64 mA. It supports surface-mount installation and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Octal D-type flip-flop architecture with positive edge triggering
• Three-state output buffers for bus-oriented applications
• TTL-compatible input structure for direct interface compatibility

Applications

• Bus-oriented memory addressing
• Registering digital data in communication systems
• High-speed data buffering in industrial control

Procurement Notes

Verify that the specific part number matches the required manufacturer specifications, as the original NXP type may be discontinued. Confirm the presence of RoHS compliance documentation and ensure the component meets the necessary environmental standards for your application. Cross-reference the datasheet to validate pinout and electrical characteristics against current design requirements before finalizing procurement.

Selection Notes

Select this component when a low-voltage, high-speed octal register with three-state outputs is required. Ensure the system voltage falls within the specified 2.7 V to 3.6 V range. Consider the SSOP-20 package constraints for PCB layout and verify that the propagation delay and drive current meet the timing and load requirements of the target circuit design.

Part Context

This component is part of the SN74LVTH574 family, designed for 3.3 V applications. It serves as a replacement or alternative for older NXP types like the 74LVTH574DB,112, which has been discontinued. The Texas Instruments version provides similar functionality with potentially updated manufacturing processes and packaging options suitable for modern surface-mount assembly techniques.

Replacement Considerations

Public confirmed substitute part numbers: SN74LVTH574ADW, SN74LVTH574APW.
