IDT29FCT2052AT/BT/CT
DESCRIPTION:
The IDT29FCT2052T 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 IDT29FCT2052T has balanced drive outputs with current limiting
resistors. This offers low ground bounce, minimal undershoot and con-
trolled output fall times-reducing the need for external series terminating
resistors. The IDT29FCT2052T is a plug-in replacement for the IDT29FCT52T.
