IDT49FCT805/A FAST CMOS BUFFER/CLOCK DRIVER 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 advanced 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.

Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause 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.

This parameter is measured at characterization but not tested. 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.
