COMMERCIAL AND INDUSTRIAL TEMPERATURE RANGE
FAST CMOS
BUFFER/CLOCK DRIVER
IDT49FCT805/A
FEATURES:
• 0.5 MICRON CMOS Technology
• Guaranteed low skew < 700ps (max.)
• Low duty cycle distortion < 1ns (max.)
• Low CMOS power levels
• TTL compatible inputs and outputs
• Rail-to-rail output voltage swing
• High drive: -24mA IOH, +64mA IOL
• Two independent output banks with 3-state control
• 1:5 fanout per bank
• "Heartbeat" monitor output
• Available in SSOP and SOIC packages
DESCRIPTION:
The 49FCT805 is a non-inverting buffer/clock driver built using ad-
vanced dual metal CMOS technology. Each bank consists of two banks of
drivers. Each bank drives five output buffers from a standard TTL
compatible input. These devices feature a “heart-beat” 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 49FCT805 offers low capacitance inputs and hysteresis. Rail-to-rail
output swing improves noise margin and allows easy interface with CMOS
inputs.

NOTE:
1. Pin 8 is not internally connected on devices with a "K" prefix in the date code. On older
devices, pin 8 is internally connected to GND. To insure compatibility with all products,
pin 8 should be connected to GND at the board level.

permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
