IDT7216L  
IDT7217L  
16 x 16 PARALLEL  
CMOS MULTIPLIERS  
Integrated Device Technology, Inc.  
FEATURES:  
• 16 x 16 parallel multiplier with double precision product  
• 16ns clocked multiply time  
• Low power consumption: 120mA  
• Produced with advanced submicron CMOS high perfor-  
mance technology  
• IDT7216L is pin- and function compatible with TRW  
MPY016H/K and AMD Am29516  
• IDT7217L requires a single clock with register enables  
making it pin- and function compatible with AMD  
Am29517  
• Configured for easy array expansion  
• User-controlled option for transparent output register  
mode  
DESCRIPTION:  
The IDT7216/IDT7217 are high-speed, low-power  
16 x 16-bit multipliers ideal for fast, real time digital signal  
processing applications. Utilization of a modified Booths  
algorithm and IDT’s high-performance, submicron CMOS  
technology,hasachievedspeedscomparabletobipolar(20ns  
max.), at 1/10 the power consumption.  
The IDT7216/IDT7217 are ideal for applications requiring  
high-speed multiplication such as fast Fourier transform  
analysis, digital filtering, graphic display systems, speech  
synthesis and recognition and in any system requirement  
where multiplication speeds of a mini/microcomputer are  
inadequate.  
All input registers, as well as LSP and MSP output regis-  
ters, use the same positive edge-triggered D-type flip-flop. In  
the IDT7216, there are independent clocks (CLKX, CLKY,  
CLKM, CLKL) associated with each of these registers. The  
IDT7217hasonlyasingleclockinput(CLK)andthreeregister  
enables. ENX and ENY control the two input registers, while  
ENP controls the entire product.  
• Round control for rounding the MSP  
• Input and output directly TTL-compatible  
• Three-state output  
• Available in Top Braze, DIP, PLCC, Flatpack and Pin  
Grid Array  
• Military product compliant to MIL-STD-883, Class B  
• Standard Military Drawing #5962-86873 is listed on this  
function for IDT7216 and Standard Military Drawing  
#5962-87686 is listed for this function for IDT7217.  
• Speeds available: Commercial: L16/20/25/35/45/55/65  
TheIDT7216/IDT7217offeradditionalflexibilitywiththeFA  
control and MSPSEL functions. The FA control formats the  
output for two’s complement by shifting the MSP up one bit  
and then repeating the sign bit in the MSB of the LSP. The  
Military:
