The SN74FB1651 contains an 8-bit and 9-bit transceiver with a buffered clock. The clock and the transceivers are designed to translate signals between TTL and backplane transceiver-logic (BTL) environments. The device is designed specifically 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 low, OEB\ is high, or VCC is less than 2.1 V, the B\ port is turned off.
The A port operates at TTL-signal levels. The A outputs reflect the inverse of the data at the B\ port when the A-port output enable (OEA) is high. When OEA is low or when VCC is less than 2
