SN74LVTH574DBR

Flip Flops Overview

The SN74LVTH574DBR is an octal D-type flip-flop featuring three-state outputs, manufactured by Texas Instruments. It belongs to the LVTH logic series and utilizes a 20-pin SSOP package for surface-mount installation. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports a non-inverting input configuration with 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 functions across an operating temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Provides eight independent edge-triggered D-type flip-flops with three-state outputs for efficient bus driving applications.
• Features low-voltage operation compatible with 3.3 V systems while maintaining TTL input thresholds.

Flip Flops Applications

• Buffer registers in digital data processing systems
• I/O port interfacing for microcontroller-based designs
• Bidirectional bus drivers requiring high drive capability

Flip Flops Procurement Notes

Verify the specific ordering suffix 'DBR' corresponds to the SSOP-20 package and reel packaging format as listed in official Texas Instruments documentation. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the supply voltage provided matches the specified 2.7 V to 3.6 V operational range to prevent device malfunction or damage during integration.

Flip Flops Selection Notes

Select this component when designing circuits requiring fast switching speeds and high output drive strength at low voltages. The LVTH series offers superior performance compared to standard HC logic in mixed-voltage environments. Consider the SSOP package size for space-constrained PCB layouts. Verify that the 32 mA source and 64 mA sink currents meet the load requirements of the connected bus lines or downstream logic gates.

Flip Flops Part Context

This part is part of the SN74LVTH574 family, which represents a line of advanced low-voltage CMOS logic devices. The family is designed to bridge the gap between traditional 5 V logic and modern 3.3 V systems. The SN74LVTH574 variant specifically targets applications needing high-speed data storage and transfer with robust output capabilities.
