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.
