General Description

The IDT8T79S838-08I is a high performance, 1-to-8, differential input

to universal output fanout buffer. The device is designed for signal

fanout of high-frequency clock signals in applications requiring output

frequencies generated simultaneously. The IDT8T79S838-08I is

optimized for 3.3V and 2.5V supply voltages and a temperature range

of -40°C to 85°C. The device is packaged in a space-saving 32 lead

VFQFN package.
