IDT7429FCT53BTPY Datasheet



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 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 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.
