The SCAN16602 and SCAN16512 chips from National Semiconductor Corp. provide easy, cost-effective testability solutions in basestations, switchers, multiplexers, and other low-voltage telecommunications systems.

The universal 16-bit transceivers enable testability of boards or entire systems, and give designers the option to use JTAG compliant buffers without paying a price penalty. They are designed for inserting test points into high-speed TTL/CMOS backplanes and operate over a voltage supply range of 2.7V to 3.6V.

Optional bus hold or series resistors on the products eliminate the need for additional pull-up/down or external termination resistors while minimizing system noise. The SCAN16602 and SCAN16512 are available in 64-bump BGA packaging at $3.25 each in 1,000-unit quantities.
