DESCRIPTION:
The IDT29FCT52A/B/C and IDT29FCT53A/B/C are 8-bit
registered transceivers manufactured 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 IDT29FCT52A/B/C is a non-inverting option of the
IDT29FCT53A/B/C.
