• Manufacturer Part Number: PALC22V10
• Description: Reprogrammable CMOS PAL Device
• Manufacturer: Cypress Semiconductor

Functional Description (continued)
The PALC22V10 is available in 24-pin 300-mil molded DIPs,
300-mil windowed cerDIPs, 28-lead square ceramic leadless
chip carriers, 28-lead square plastic leaded chip carriers, and
provides up to 22 inputs and 10 outputs. When the windowed
cerDIP is exposed to UV light, the 22V10 is erased and can
then be reprogrammed. The programmable macrocell pro-
vides the capability of defining the architecture of each output

individually. Each of the 10 potential outputs may be specified
as registered or combinatorial. Polarity of each output may
also be individually selected, allowing complete flexibility of
output configuration. Further configurability is provided
through array-configurable output enable for each potential
output. This feature allows the 10 outputs to be reconfigured
as inputs on an individual basis, or alternately used as a com-
bination I/O controlled by the programmable array.
