74FCT20807PYGI

Overview

The 74FCT20807PYGI is a single clock fan-out buffer manufactured by Renesas Electronics Corporation. It provides a 1:10 input-to-output ratio, distributing a single TTL-compatible input signal to ten LVTTTL outputs. The device operates within a supply voltage range of 2.3V to 2.7V and supports maximum frequencies up to 166 MHz. It is housed in a 20-SSOP package with a width of 3.90mm and functions reliably across an industrial temperature range of -40°C to 85°C.

Feature Summary

• Single circuit configuration with 1:10 fan-out ratio
• Maximum operating frequency of 166 MHz
• LVTTTL output drivers compatible with low-voltage logic systems
• Industrial temperature rating from -40°C to 85°C

Applications

• Clock distribution networks requiring high-speed signal splitting
• System boards utilizing 2.5V logic families
• High-frequency timing synchronization circuits

Procurement Notes

This component is listed as obsolete or end-of-life. Verification of current stock availability through authorized distributors is required before procurement planning. Alternative sources may be limited due to the discontinuation status.

Selection Notes

Select this part for applications requiring a 166 MHz buffer with LVTTTL outputs at 2.5V. Ensure the design accommodates the 20-SSOP footprint. Verify that the system power supply strictly adheres to the 2.3V–2.7V range to maintain signal integrity and operational stability.

Part Context

The 74FCT20807 series belongs to the 74FCT family of fast CMOS logic devices. This specific variant is optimized for lower voltage operation (2.5V) compared to standard 3.3V variants, targeting legacy or specialized low-power digital systems requiring precise clock distribution.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult manufacturer obsolescence notices for recommended next-generation replacements.
