SN74FB2033A - 8-Bit TTL/BTL Registered Transceiver
The SN74FB2033A is an 8-bit transceiver featuring a split input (AI) and output (AO) bus on the TTL-level A port.
The common-I/O, open-collector B port operates at backplane transceiver logic (BTL) signal levels.
The logic element for data flow in each direction is configured by two mode inputs (IMO
