IDTQS3VH800PAG

Overview

The IDTQS3VH800PAG is a discontinued digital bus switch IC manufactured by Renesas Electronics Corporation. It features a single circuit configuration with ten independent 1:1 bidirectional switches, providing a total of ten bits of data path capability. The device operates within a supply voltage range of 2.3 V to 3.6 V and supports surface-mount installation in a 24-TSSOP package with a width of 4.40 mm. It is designed for low-voltage applications and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides ten independent bidirectional data paths for signal routing
• Supports low-voltage operation between 2.3 V and 3.6 V
• Features flow-through architecture for simplified PCB layout

Applications

• Portable equipment requiring low-voltage signal switching
• Consumer electronics utilizing 3.3 V logic systems
• Industrial control systems needing isolated data paths

Procurement Notes

This component has been officially discontinued and is no longer in production. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer allocation. Buyers must confirm the authenticity of existing stock and review any Product Change Notices (PCN) regarding material or process alterations that may affect long-term reliability. Design-in substitution is strongly recommended for new projects.

Selection Notes

Engineers selecting this part should note its specific 10-bit configuration and 24-pin TSSOP footprint. The device is suitable for designs requiring multiple bidirectional switches within a compact surface-mount package. Compatibility with 3.3 V logic families is a primary consideration. Due to its end-of-life status, alternative components with equivalent pinouts and electrical characteristics should be evaluated to ensure supply chain stability for future manufacturing phases.

Part Context

The IDTQS3VH800PAG belongs to the QS3VH series of high-speed bus switches from Renesas Electronics. This family is characterized by low on-resistance and fast switching speeds, making it suitable for high-frequency data transmission applications. The part represents a legacy product line previously managed under the IDT brand before integration into Renesas's portfolio, maintaining compatibility with standard CMOS logic interfaces.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the 74CBTLV3861PGG and 74CBTLV3861PGG8 from Renesas Electronics. Other potential equivalents listed in distributor databases include Texas Instruments parts such as CCBTLV3861IPWRG4Q1 and CCBTLV3861IPWRQ1, though functional verification is required.
