IDT49FCT805PY8

Clock Buffers, Drivers Overview

The IDT49FCT805PY8 is a non-inverting buffer and clock driver manufactured by Renesas Electronics Corporation, utilizing advanced dual metal CMOS technology. It features two independent output banks, each driving five buffers from a standard TTL-compatible input. The device includes a 'heartbeat' monitor output for diagnostics and PLL driving. Electrical specifications include low skew under 700ps maximum, duty cycle distortion under 1ns maximum, and high drive capability of -24mA IOH and +64mA IOL. It operates within a commercial temperature range of 0°C to +70°C.
