The LMU08 and LMU8U are highspeed, low power 8-bit parallel multipliers. They are pin-for-pin equivalents with TRW TMC208K and TMC28KU type multipliers. Full military ambient temperature range operation is attained by the use of advanced
CMOS technology.
Both the LMU08 and the LMU8U produce the 16-bit product of two 8-bit numbers. The LMU08 accepts operands in two’s complement format, and produces a two’s complement result. The product is provided in two halves with the sign bit replicated as the most significant bit of both halves.
