LOGIC Devices Incorporated LMU08
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. This facilitates use of the LMU08 product as a double precision operand in 8-bit systems.DESCRIPTION
Full military ambient temperature range operation is attained by the use of advanced CMOS technology. The LMU8U operates on unsigned data, producing an unsigned magnitude result.FEATURES

The LMU08 accepts microprocessor busses. Provision is operands in two’s complement format, made in the LMU08 and LMU8U for proper rounding of the product to and produces a two’s complement result. The product is provided in two 8-bit precision. The round input is halves with the sign bit replicated as loaded at the rising edge of the logical the most significant bit of both halves.
