DESCRIPTION:
The IDT49FCT805BT/CT and IDT49FCT806BT/CT are clock drivers built using advanced dual metal CMOS technology. The IDT49FCT805BT/CT is a non-inverting clock driver and the IDT49FCT806BT/CT 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 805BT/CT and 806BT/CT have extremely low output skew, pulse skew, and package skew. The devices 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 805BT/CT and 806BT/CT offer low capacitance inputs with hysteresis.

1.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. Exposure to absolute maximum rating conditions for extended periods may affect reliability. No terminal voltage may exceed VCC by +0.5V unless otherwise noted.
