SN74FB1650

18BIT TTL/BTL UNIVERSAL STORAGE TRANSCEIVER

SCBS178O − AUGUST 1992 − REVISED MARCH 2004

POST OFFICE BOX 655303

• DALLAS, TEXAS 75265

description/ordering information

The SN74FB1650 contains two 9-bit transceivers 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 2.1 V, the A outputs are in the

high-impedance state.

BIAS VCC establishes a voltage between 1.62 V and 2.1 V on the BTL outputs when VCC is not connected.

BG VCC and BG GND are the supply inputs for the bias generator.
