29F52*29F53 8-Bit Registered Transceiver
April 1988 Revised August 1999
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 provided for each register. The A0-A7 output pins are guaranteed 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 transceivers are AMD Am2952/2953 functional equivalents.
