8312AYILFT

Overview

The 8312AYILFT is a low skew LVCMOS fanout buffer manufactured by Renesas Electronics. It functions as a clock distribution component with a 1:12 output ratio, designed to maintain signal integrity across multiple loads. The device operates within a supply voltage range of 3 V to 3.6 V and supports maximum input frequencies up to 200 MHz. It is housed in a TQFP-32 surface-mount package and is rated for commercial operating temperatures between 0°C and +70°C. This component belongs to the 8312 series of clock buffers.

Feature Summary

• 1:12 LVCMOS Fanout Buffer configuration
• Low skew performance for precise timing
• Maximum input frequency of 200 MHz
• TQFP-32 surface mount package

Applications

• Clock distribution in digital systems
• LVCMOS logic interface buffering
• High-speed data processing circuits

Procurement Notes

The 8312AYILFT is listed as an obsolete or end-of-life product by Renesas Electronics. Availability is limited to existing stock from distributors. Verification of authenticity and storage history is critical due to the component's discontinued status. Buyers should confirm RoHS compliance details directly with suppliers before procurement.

Selection Notes

Select this component when a single LVCMOS clock source needs to drive twelve downstream loads with minimal skew. Ensure the system power supply remains within the 3 V to 3.6 V range. Verify that the required operating temperature falls within the commercial grade limits of 0°C to +70°C. Consider the TQFP-32 footprint constraints during PCB layout.

Part Context

This part is part of the Renesas 8312 series of clock buffers. It serves as a replacement for legacy ICS (Integrated Circuit Systems) parts, specifically the ICS8312AYLFT. The 'AY' suffix typically denotes the package type and temperature range, while 'LFT' indicates lead-free and tape-and-reel packaging variations compared to tray versions.

Replacement Considerations

Direct pin-to-pin replacements may include the ICS8312AYLFT. Verify electrical parameters such as skew and output drive strength against the original design requirements. Since the part is obsolete, evaluate alternative Renesas clock buffers with similar 1:12 ratios if long-term supply stability is required.
