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.
