Overview

The FCT3807/A 3.3V clock driver is built using advanced dual metal CMOS technology. This low skew clock driver offers 1:10 fanout. The large fanout from a single input reduces loading on the preceding driver and provides an efficient clock distribution network. The FCT3807/A offers low capacitance inputs with hysteresis for improved noise margins. Multiple power and grounds reduce noise. Typical applications are clock and signal distribution.

  1. Vcc for 74FCT3807A for 5V TTL application

    I am planning on using the 74FCT3807A for 1:10 fanout of a 5V TTL signal. Should Vcc be set to 5V or 3.3V?
