FBL22041
• 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
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
terminating resistors unnecessary
impedances down to 10Ω.
• 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
DESCRIPTION
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.
power consumption
• Built-in precision band-gap reference provides accurate receiver
The B-port drivers are Low-capacitance open collectors with
controlled ramp and are designed to sink 100mA. 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.
thresholds and improved noise immunity
• Compatible with IEEE Futurebus+ or proprietary BTL backplanes
• Controlled output ramp and multiple GND pins minimize ground
The FBL22041 is designed with a 30Ω series resistance in both the
HIGH and LOW states of the output.
bounce
• Each BTL driver has a dedicated Bus GND for a signal return
• Glitch-free power up/power down operation
• Low ICC current
The FBL22041 is pin and function compatible with FB2041 but
operates at a 3.3V supply voltage, greatly reducing power
consumption.

The B-port interfaces to “Backplane Transceiver Logic” (See the
IEEE 1194.1 BTL standard). BTL features low power consumption
by reducing voltage swing (1Vp-p, between 1V and 2V) and reduced
capacitive loading by placing an internal series diode on the drivers.
BTL also provides incident wave switching, a necessity for high
performance backplanes.
The A-port operates at TTL levels with separate I/O. The 3-state
A-port drivers are enabled when OEAn goes High after an extra 6ns
delay which is built in to provide a break-before-make function.
When OEAn goes Low, A-port drivers become High impedance
without any extra delay. During power on/off cycles, the A-port
drivers are held in a High impedance state when VCC is below 1.3V.
There are three separate pairs of driver enables in a 1 bit, 3 bit, 3 bit
arrangement. The TTL/BTL output drivers for bit 0 are enabled with
OEA1/OEB1, output drivers for bits 1–2–3 are enabled with
OEA2/OEB2 and output drivers for bits 4–5–6 are enabled with
OEA3/OEB3.
The B-port has an output enable, OEB0, which affects all seven
drivers. When OEB0 is High and OEBn is Low the output driver will
be enabled. When OEB0 is Low or if OEBn is High, the B-port
drivers will be inactive and at the level of the backplane signal.

Definitions
Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended
periods may affect device reliability.
Application information — Applications that are described herein for any of these products are for illustrative purposes only. Philips
Semiconductors make no representation or warranty that such applications will be suitable for the specified use without further testing or
modification.
Disclaimers
Life support — These products are not designed for use in life support appliances, devices or systems where malfunction of these products can
reasonably be expected to result in personal injury. Philips Semiconductors customers using or selling these products for use in such applications
do so at their own risk and agree to fully indemnify Philips Semiconductors for any damages resulting from such application.
Right to make changes — Philips Semiconductors reserves the right to make changes, without notice, in the products, including circuits, standard
cells, and/or software, described or contained herein in order to improve design and/or performance. Philips Semiconductors assumes no
responsibility or liability for the use of any of these products, conveys no license or title under any patent, copyright, or mask work right to these
products, and makes no representations or warranties that these products are free from patent, copyright, or mask work right infringement, unless
