The MAX 3000A architecture supports 100% transistor-to-transistor logic
(TTL) emulation and high–density small-scale integration (SSI),
medium-scale integration (MSI), and large-scale integration (LSI) logic
functions. The MAX 3000A architecture easily integrates multiple devices
ranging from PALs, GALs, and 22V10s to MACH and pLSI devices.
MAX 3000A devices are available in a wide range of packages, including
PLCC, PQFP, and TQFP packages. See
Note:
(1)
MAX 3000A devices use CMOS EEPROM cells to implement logic
functions. The user–configurable MAX 3000A architecture accommodates
a variety of independent combinatorial and sequential logic functions.
The devices can be reprogrammed for quick and efficient iterations
during design development and debugging cycles, and can be
programmed and erased up to 100 times.

When the IEEE Std. 1149.1 (JTAG) interface is used for in–system programming or
boundary–scan testing, four I/O pins become JTAG pins.
