8312AYLFT

Overview

The 8312AYLFT is a low skew LVCMOS fanout buffer manufactured by Renesas Electronics. It functions as a clock buffer with one input and twelve outputs, designed for signal distribution in digital systems. 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 and is identified by the alias ICS8312AYLF.

Feature Summary

• 1:12 LVCMOS Fanout Buffer configuration
• Maximum input frequency of 200 MHz
• Supply voltage range of 3 V to 3.6 V
• TQFP-32 surface-mount packaging

Applications

• Clock distribution networks requiring low skew
• LVCMOS logic system synchronization
• Digital signal routing in consumer electronics

Procurement Notes

The 8312AYLFT is listed as an obsolete or end-of-life product by Renesas Electronics. Availability through major distributors such as Mouser is currently restricted or non-existent in many regions. Verification of lifecycle status and potential last-time-buy options is required before procurement planning.

Selection Notes

Designers should verify compatibility with LVCMOS voltage levels and ensure the 200 MHz frequency limit meets system requirements. The TQFP-32 package dimensions must be checked against PCB layout constraints. Due to the obsolete status, alternative components with similar pinouts and electrical specifications should be evaluated for long-term production viability.

Part Context

The 8312AYLFT is part of the Renesas 8312 series of clock buffers. It is also known under the alias ICS8312AYLF, reflecting its historical association with Integrated Circuit Specialties (ICS), which was acquired by Renesas. The 'Y' suffix typically denotes the temperature grade, while 'L' indicates lead-free compliance.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Given the obsolete status, engineers must identify functional equivalents from current Renesas portfolios or other manufacturers that match the 1:12 LVCMOS fanout ratio, 200 MHz speed, and TQFP-32 package.
