ATV750B(L)
0301I–08/01
Each of the ATV750B(L) 22 logic pins can be used as an input. Ten of these can be used as
inputs, outputs or bi-directional I/O pins. Each flip-flop is individually configurable as either D-
or T-type. Each flip-flop output is fed back into the array independently. This allows burying of
all the sum terms and flip-flops.
There are 171 total product terms available. A variable format is used to assign between four
to eight product terms per sum term. There are two sum terms per output, providing added
flexibility. Much more logic can be replaced by this device than by any other 24-pin PLD. With
20 sum terms and flip-flops, complex state machines are easily implemented with logic to
spare.
Product terms provide individual clocks and asynchronous resets for each flip-flop. Each flip-
flop may also be individually configured to have direct input pin controlled clocking. Each out-
put has its own enable product term. One product term provides a common synchronous
preset for all flip-flops. Register preload functions are provided to simplify testing. All registers
automatically reset upon power-up.
The ATV750BL is a low-power device with speeds as fast as 15 ns. The ATV750BL provides
the optim um low-power PLD solution, with full CMOS output levels. This device
significantly reduces total system power, thereby allowing battery-powered operation.
Logic Options
Absolute Maximum Ratings*
Temperature Under Bias................................ -55°C to +125°C
*NOTICE: Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect
device reliability.
