by reducing voltage swing (1V p-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.
DESCRIPTION
The FBL22033 is an 8-bit transceiver featuring a split input (AI) and
output (AO) bus on the TTL-level side.
The common I/O, open collector B port operates at BTL signal
levels. The logic element for data flow in each direction is controlled
by two pairs of mode select inputs (SBA0 and SBA1 for B-to-A,
SAB0 and SAB1 for A-to-B). It can be configured as a buffer, a
register, or a D-type latch.
Output clamps are provided on the BTL outputs to further reduce
switching noise. The “VOH” clamp reduces inductive ringing effects
during a Low-to-High transition. The “VOH” clamp is always active.
The other clamp, the “trapped reflection” clamp, clamps out ringing
below the BTL 0.5V VOL level. This clamp remains active for
approximately 100ns after a High-to-Low transition.
When configured in the buffer mode, the inverse of the input data
appears at the output port. In the flip-flop mode, data is stored on
the rising edge of the appropriate clock input (LCAB or LCBA). In the
latch mode, clock pins serve as transparent-High latch enables.
Regardless of the mode, data is inverted from input to output.
To support live insertion, OEB0 is held Low during power on/off
cycles to ensure glitch- free B port drivers. Proper bias for B port
drivers during live insertion is provided by the BIAS V pin when at a
3.3V level while VCC is Low. The BIAS V pin is a low current input
which will reverse-bias the BTL driver series Schottky diode, and
also bias the B port output pins to a voltage between 1.62V and
2.1V. This bias function is in accordance with IEEE BTL Standard
1194.1. If live insertion is not a requirement, the BIAS V pin should
be tied to a VCC pin.
Data flow in the B-to-A direction, regardless of the logic element
selected, is further controlled by the Loopback input. When the
Loopback input is High the output of the selected A-to-B logic
element (not inverted) becomes the B-to-A input.
The 3-State AO port is enabled by asserting a High level on OEA.
The B port has two output enables, OEB0 and OEB1. Only when
OEB0 is High and OEB1 is Low is the output enabled. When either
OEB0 is Low or OEB1 is High, the B-port is inactive and is pulled to
the level of the pull-up voltage. New data can be entered in the
flip-flop and latched modes or can be retained while the associated
outputs are in 3-State (AO port) or inactive (B port).
The LOGIC GND and BUS GND pins are isolated inside the
package to minimize noise coupling between the BTL and TTL
sides. These pins should be tied to a common ground external to the
package.
Each BTL driver has an associated BUS GND pin that acts as a
signal return path and these BUS GND pins are internally isolated
from each other. In the event of a ground return fault, a “hard” signal
failure occurs instead of a pattern dependent error that may be very
infrequent and impossible to trouble- shoot.
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 ensure very good noise margins by
limiting the switching threshold to a narrow region centered at 1.55V.
As with any high power device thermal considerations are
critical. It is recommended that airflow (300Ifpm) and/or thermal
mounting be used to ensure proper junction temperature.
The B-port interfaces to “Backplane Transceiver Logic” (see the
IEEE 1194.1 BTL standard). BTL features low power consumption

1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operation conditions for the applicable type.
2. All typical values are at VCC = 3.3V, TA = 25°C.
3. Due to test equipment limitations, actual test conditions are VIH = 1.8V and VIL = 1.3V for the B side.
4. Unused pins are at VCC or GND.
5. For B port input voltage between 3 and 5 volt; IIH will be greater than 100mA but the part will continue to function normally (clamping circuit

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
