IDT49FCT3805B

3.3V CMOS BUFFER/CLOCK DRIVER

COMMERCIAL AND INDUSTRIAL TEMPERATURE RANGE

3.3V CMOS

BUFFER/CLOCK DRIVER

IDT49FCT3805B

FEATURES:

•

DESCRIPTION:

0.5 MICRON CMOS Technology

Guaranteed low skew < 500ps (max.)

Very low duty cycle distortion < 1.0ns (max.)

Very low CMOS power levels

TTL compatible inputs and outputs

Inputs can be driven from 3.3V or 5V components

Two independent output banks with 3-state control

1:5 fanout per bank

"Heartbeat" monitor output

= 3.3V ± 0.3V

Available in SSOP, SOIC, and QSOP packages

The FCT3805B is a 3.3 volt, non-inverting clock driver built using

advanced dual metal CMOS technology. The device consists of two banks

of drivers, each with a 1:5 fanout and its own output enable control. The

device has a "heartbeat" monitor for diagnostics and PLL driving. The

MON output is identical to all other outputs and complies with the output

specifications in this document. The FCT3805B offers low capacitance

inputs with hysteresis.

The FCT3805B is designed for high speed clock distribution where

signal quality and skew are critical. The FCT3805B also allows single

point-to-point transmission line driving in applications such as address

distribution, where one signal must be distributed to multiple recievers with

low skew and high signal quality.

For more information on using the FCT3805B with two different input

frequencies on bank A and B, please see AN-236.
