SN74FB2040 - 8-Bit TTL/BTL Transceiver
The SN74FB2040 is an 8-bit transceiver designed to translate signals between TTL and backplane transceiver logic (BTL) environments.
The B port operates at BTL-signal levels.
The open-collector B ports are specified to sink 100 mA.
Two output enables (OEB and OEB) are provided for the B outputs.
