PI49FCT3805CQEX

Clock Buffers, Drivers Overview

The PI49FCT3805CQEX is a non-inverting clock driver manufactured by Diodes Incorporated, utilizing advanced submicron CMOS technology. It features two independent groups of buffers, each configured with one input and five outputs (1:5 fanout), along with an independent active-low output enable for each group. Group B includes an additional MON output identical to the standard outputs. The device operates at a supply voltage of 3.3V ±10% and supports switching frequencies up to 166 MHz. Key electrical characteristics include low propagation delay (<2.5ns), fast rise/fall times (<1.0ns), and extremely low output skew (<200ps).

Clock Buffers, Drivers Feature Summary

• Two independent 1:5 buffer groups with active-low output enables.
• Low output skew of less than 200ps and propagation delay under 2.5ns.
• Supports switching frequencies up to 166 MHz with fast rise/fall times under 1.0ns.
• Includes a dedicated MON output on Group B for diagnostics or PLL driving.

Clock Buffers, Drivers Applications

• High-speed clock distribution networks requiring minimal signal skew.
• Address distribution systems where single point-to-point transmission line driving is required.
• PLL driving applications utilizing the monitor output functionality.

Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix 'E' confirms lead-free and green status, and 'X' indicates tape and reel packaging. Confirm compliance with EU RoHS directives and halogen/antimony-free definitions before procurement. Ensure the component meets industrial temperature range requirements (-40°C to +85°C) for the intended environment.

Clock Buffers, Drivers Selection Notes
