DESCRIPTION
The LVT22V10 is a versatile PAL® device fabricated on the Philips
BiCMOS QUBiC process.
The QUBiC process produces very high speed 3V devices (7.5ns)
which have excellent noise characteristics. Ground bounce of an
output held low while the remaining 9 outputs switch from high to
low is typically less than 0.7V. V
CC
bounce of an output held high
while the remaining 9 outputs switch from low to high is typically less
than 1.0V.
The LVT22V10 was designed to support mixed 3/5V systems. The
inputs are capable of handling 7V while the outputs can be pulled up
to 7V.
The designer can interface directly from 5V outputs (CMOS full rail
or totem pole) to a 3V LVT input. A 3V LVT output can drive a 5V
TTL input directly, or in the case of a CMOS input, the LVT output
can interface with the use of an external pull-up resistor. Finally, no
external pull-up resistors are needed on unused input pins due to a
bus-hold data structure designed into the LVT input.
The LVT22V10 has been designed with high drive outputs (32mA
sink and 16mA source currents), which allows for direct connection
to a backplane bus. This feature eliminates the need for additional,
standalone bus drivers, which are traditionally required to boost the
drive of a standard PLDs.
The LVT22V10 outputs are designed to support Live
Insertion/Extraction into powered up systems. The output is
specially designed so that during V
CC
ramp, the output remains
3-Stated until V
CC
[
2.1V. At that time the outputs become fully
functional depending upon device inputs. (See DC Electrical
Characteristics, Symbol I
PU/PD,
Page 5). In addition when an
LVT22V10 output is tied to a 5V bus, no bus current is loaded.
The LVT22V10 uses the familiar AND/OR logic array structure,
which allows direct implementation of sum-of-products equations.
This device has a programmable AND array which drives a fixed OR
array. The OR sum of products feeds an “Output Macro Cell” (OMC)
which can be individually configured as a dedicated input, a
combinatorial output, or a registered output with internal feedback.

NOTES:
1. These are absolute values with respect to device ground and all overshoots due to system or tester noise are included.
2. The bus hold circuit can sink at least the minimum low sustaining current at V
IL
MAX. I
BHL
should be measured after lowering V
IN
to GND
and then raising it to V
IL
MAX.
3. The bus hold circuit can source at least the minimum high sustaining current at V
IH
MIN. I
BHL
should be measured after raising V
IN
to V
CC
and then lowering it to V
IH MIN.
4. An external driver must source at least I
BHLO
to switch this node from low to high.
5. An external driver must sink at least I
BHHO
to switch this node from high to low.
6. I/O pin leakage is the worst case of I
OZX
or I
IX
(where X = H or L).
7. No more than one output should be tested at a time. Duration of the short-circuit test should not exceed one second. V
OUT
= 0.5V has been
chosen to avoid test problems caused by tester ground degradation.
8. This parameter is valid for any V
CC
between 0V and 1.2 V with a transition time up to 10 mS. From V
CC
= 1.2 to V
CC
= 3.3V
±0.3V
a
transition time of 100
µS
is permitted. X = Don’t care.
9. These parameters are not 100% tested, but are evaluated at initial characterization and at any time the design is modified where input
current may be affected.
