LMU08/8U  
8 x 8-bit Parallel Multiplier  
DEVICES INCORPORATED  
FEATURES  
DESCRIPTION  
The LMU08 and LMU8U are high-  
speed, 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.  
This facilitates use of the LMU08  
product as a double precision operand  
in 8-bit systems. The LMU8U oper-  
ates on unsigned data, producing an  
unsigned magnitude result.

Two’sComplement(LMU08),or  
Both the LMU08 and the LMU8U  
feature independently controlled  
registers for both inputs and the  
product, which along with three-state  
outputs allows easy interfacing with  
microprocessor busses. Provision is  
Unsigned Operands (LMU8U)  
Three-State Outputs  
Package Styles Available:  
Both the LMU08 and the LMU8U  
produce the 16-bit product of two  
8-bit numbers. The LMU08 accepts  
• 40-pin PDIP  
• 44-pinPLCC, J-Lead  
operands in two’s complement format, made in the LMU08 and LMU8U for  
and produces a two’s complement proper rounding of the product to  
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. OR of CLK A and CLK B for the  
LMU08. The LMU8U latches RND on  
the rising edge of CLK A only. In  
either case, a ‘1’ is added in the most

Subsequent truncation of the least  
significant product byte results in a
