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 TRI-STATE output enable signals are provided for each register The A0 - A7 output pins are guaranteed to sink 24 mA (20 mA mil ) 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
Features
