DESCRIPTION:
The IDT29FCT2052AT/BT/CT/DT is an 8-bit registered transceiver
built using an advanced dual metal CMOS technology. Two 8-bit back-to-
back registers store data flowing in both directions between two bidirectional
buses. Separate clock, clock enable and 3-state output enable signals are
provided for each register. Both A outputs and B outputs are guaranteed
to sink 64mA.
The IDT29FCT2052AT/BT/CT has balanced drive outputs with current
limiting resistors. This offers low ground bounce, minimal undershoot and
controlled output fall times-reducing the need for external series terminating
resistors. The IDT29FCT2052T part is a plug-in replacement for the
IDT29FCT52T part.
