74FCT807CTPYGI

Overview

The 74FCT807CTPYGI is a clock driver and distribution integrated circuit manufactured by Renesas Electronics Corporation. It functions as a 1:10 fan-out buffer with TTL outputs, designed for high-speed clock signal distribution. The device operates within a supply voltage range of 4.75V to 5.25V and supports maximum frequencies up to 100 MHz. It features LVTTL input compatibility and CMOS/TTL output drive capabilities. The component is housed in a 20-SSOP package (0.209 inch width) and is rated for an operating temperature range of -40°C to +85°C. This specific part number indicates the commercial temperature grade variant.

Feature Summary

• 1:10 Clock Fan-Out Buffer with TTL Outputs
• Maximum Operating Frequency of 100 MHz
• Supply Voltage Range: 4.75V to 5.25V
• LVTTL Input / CMOS and TTL Output Compatibility

Applications

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm that the 74FCT807CTPYGI designation corresponds to the commercial temperature grade (-40°C to +85°C) and 20-SSOP package. Check for end-of-life status or obsolescence notices from Renesas Electronics prior to procurement planning.

Selection Notes

Select this component when a single-ended 1:10 clock distribution solution with TTL-compatible outputs is required at 5V logic levels. Ensure the design environment supports the specified 4.75V to 5.25V supply voltage. Verify that the 20-SSOP footprint matches the PCB layout requirements and that the thermal characteristics are suitable for the intended operating temperature range.

Part Context

This part belongs to the 74FCT series of Fast CMOS TTL-compatible logic devices. The 'C' suffix typically denotes the commercial temperature grade, distinguishing it from military or extended temperature variants. It is functionally related to other 74FCT807 variants differing primarily in packaging or temperature rating.
