FUNCTIONAL DESCRIPTION
The LVT22V10 allows the systems engineer to implement the
design on-chip, by opening fuse links to configure AND and OR
gates within the device, according to the desired logic function.
Product terms with all fuses opened assume the logical HIGH state;
product terms connected to both True and Complement of any
single input assume the logical LOW state.
The LVT22V10 has 12 inputs and 10 I/O Macro Cells (Figure 1). The
Macro Cell allows one of four potential output configurations,
registered output or combinatorial I/O, Active-HIGH or Active-LOW
(see Figure 2). The configuration choice is made according to the
user’s design specification and corresponding programming of the
configuration bits S

. Multiplexer controls are connected to
ground (0) through a programmable fuse link, selecting the “0” path
through the multiplexer. Programming the fuse disconnects the
control line from GND and it floats to V
CC
(1), selecting the “1” path.
