SN74LVC823ADBR

Flip Flops Overview

The SN74LVC823ADBR is a 9-bit bus-interface flip-flop with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage of 1.65 V to 3.6 V and accepts input voltages up to 5.5 V. The device features a maximum propagation delay of 7.9 ns at 3.3 V. It provides high-level output current of -24 mA and low-level output current of 24 mA. The component is housed in a 24-pin SSOP package and supports surface-mount installation.

Flip Flops Feature Summary

• Provides 9-bit bus interface functionality with tri-state outputs for efficient data transfer
• Compatible with mixed 5-V and 3-V systems through 5.5-V tolerant inputs
• Designed for low power consumption with typical quiescent current of 10 µA

Flip Flops Applications

• High-density memory register applications
• Clocked bus-oriented transfers
• Optical encoding

Flip Flops Procurement Notes

Verify the specific datasheet revision (Rev. I) when sourcing, as electrical characteristics may vary between updates. Confirm that the 24-pin SSOP package matches your PCB footprint requirements. Ensure the operating temperature range of -40°C to 85°C aligns with your environmental specifications before finalizing procurement.

Flip Flops Selection Notes

Select this component when a 9-bit wide data path is required with tri-state control. It is suitable for designs needing 5.5-V input tolerance while operating on lower supply voltages. Consider the 7.9 ns propagation delay for timing constraints. This part is appropriate for applications requiring low power dissipation and high-speed bus interfacing within the specified voltage range.

Flip Flops Part Context

This device belongs to the LVC logic family, designed for low-voltage CMOS applications. It serves as a specialized variant within the broader SN74LV series, focusing on 9-bit width rather than standard octal configurations. The DBR suffix indicates the specific tape-and-reel packaging format used for automated assembly processes.

Flip Flops Replacement Considerations

Direct substitutes include other 9-bit bus-interface flip-flops with 3-state outputs from compatible logic families. Verify pin compatibility and voltage tolerances when considering alternatives. Cross-reference with SN74LVC823 variants or similar 24-pin SSOP components if package changes are permissible.
