(-12mA IOH, 12mA IOL Mil.) – Reduced system switching noise 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 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. FUNCTIONAL BLOCK DIAGRAM(1) CPA CEA A0 A1 A2 A3 A4 A5 A6 A7 D 0 CE CP Q0 D1 D2 Q1 Q2 OEB B0 B1 B2 B3 B4 B5 B6 B7 D3 Q3 A Reg.
