FAST CMOS OCTAL REGISTERED TRANSCEIVERS IDT29FCT52AT/BT/CT/DT IDT29FCT2052AT/BT/CT IDT29FCT53AT/BT/CT 1 The IDT logo is a registered trademark of Integrated Device Technology, Inc. FEATURES: • Common features: – Low input and output leakage ≤1µA (max.) – CMOS power levels – True TTL input and output compatibility – VOH = 3.3V (typ.) – VOL = 0.3V (typ.) – Meets or exceeds JEDEC standard 18 specifications – Product available in Radiation Tolerant and Radiation Enhanced versions – Military product compliant to MIL-STD-883, Class B and DESC listed (dual marked) – Available in DIP, SOIC, SSOP, QSOP, CERPACK and LCC packages • Features for 29FCT52/29FCT53T: – A, B, C and D speed grades – High drive outputs (-15mA IOH, 64mA IOL) – Power off disable outputs permit “live insertion” • Features for 29FCT2052T: – A, B and C speed grades – Resistor outputs (-15mA IOH, 12mA IOL Com.) (-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 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.
