DESCRIPTION:
The IDT29FCT52AT/BT/CT/DT and IDT29FCT53AT/BT/
CT are 8-bit registered transceivers built using an advanced
dual metal CMOS technology. Two 8-bit back-to-back regis-
ters store data flowing in both directions between two bidirec-
tional 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 IDT29FCT52AT/BT/CT/DT and IDT29FCT2052AT/BT/
CT are non-inverting options of the IDT29FCT53AT/BT/CT.
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
IDT29FCT52T part.
