29F52•29F53
8-Bit Registered Transceiver
General Description
The 29F52 and 29F53 are 8-bit registered transceivers.
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 pro-
vided for each register. The A0–A7 output pins are guaran-
teed to sink 24 mA while the B0–B7 output pins are
designed for 64 mA.
The 29F53 is an inverting option of the 29F52. Both trans-
ceivers are AMD Am2952/2953 functional equivalents.
