AM2952 Datasheet PDF

REI Datasheet AM2952, AM2952A, AM2953, AM2953A Eight-Bit Bidirectional I/O Ports with Handshake Two eight-bit, back-to-back registers store data moving in both directions between two bidirectional, 3-state busses. On chip flag flip-flops, set automatically when a register is loaded, provide the handshaking signals required for demand-response data transfer. Considerable flexibility is designed into the AM2952/AM2953. Separate Clock, Clock Enable, and Three-State Output Enable signals are provided for each register, and edge-sensitive clear inputs are provided for each flag flip-flop. A number of these circuits can be used for wider I/O ports. Both inverting and non-inverting versions are available.
