NXP Semiconductors FBL22041
The FBL22041 is a 7-bit bidirectional BTL transceiver and is intended to provide the electrical interface to a high performance wired-OR bus. The FBL22041 is an inverting transceiver. The B-port drivers are Low-capacitance open collectors with controlled ramp and are designed to sink 100mA.| Part No. | FBL22041 |

FEATURES
● 7-bit BTL transceiver● Separate I/O on TTL A-port
● Inverting
● Three separate pairs of driver enables in a 1 bit, 3 bit, 3 bit arrangement
● Drives heavily loaded backplanes with equivalent load impedances down to 10Ω.
● Tight output skew
● Supports live insertion
● Pins for the optional JTAG boundary scan function are provided
● High density packaging in plastic Quad Flatpack
● 5V compatible I/O on A-port
● The A port includes a series resistor of 30Ω making external terminating resistors unnecessary
● High drive 100mA BTL open collector drivers on B-port
● Allows incident wave switching in heavily loaded backplane buses
● Reduced BTL voltage swing produces less noise and reduces power consumption
DESCRIPTION
The FBL22041 is an inverting transceiver. Precision band gap references on the B-port insure very good noise margins by limiting the switching threshold to a narrow region centered at 1.55V. The FBL22041 is designed with a 30Ω series resistance in both the HIGH and LOW states of the output.
