DESCRIPTION:
The IDT49FCT805/A and IDT49FCT806/A are clock
drivers built using advanced dual metal CMOS technology.
The IDT49FCT805/A is a non-inverting clock driver and the
IDT49FCT806/A is an inverting clock driver. Each device
consists of two banks of drivers. Each bank drives five output
buffers from a standard TTL compatible input. The devices
feature 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
IDT49FCT805/A and IDT49FCT806/A offer low capacitance
inputs with hysteresis. Rail-to-rail output swing improves
noise margin and allows easy interface with CMOS inputs.
