description

The SN74FB2041A is a 7-bit transceiver designed to translate signals between TTL and backplane transceiver

logic (BTL) environments. The device is specifically designed to be compatible with IEEE Std 1194.1-1991.

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. When OEB is high and OEB is low, the B port is active

than 2.1 V, the B port is turned off. The enable/disable logic partitions the device as two 3-bit sections and one

1-bit section.

The A port operates at TTL signal levels and has split input and output pins. The A outputs reflect the inverse

than 2.1 V, the A outputs are in the high-impedance state.
