Fabricated using CMOS silicon gate technology, this device offers a very low-power alternative to existing bipolar and NMOS counterparts, with only 1/7 to 1/10 the power dissipation and exceptional speed (25ns maximum) performance. A pin and functional replacement for TRW’s TDC1010J the IDT7210 operates from a single 5 volt supply and is patible with standard TTL logic levels. The architecture of the IDT7210 is fairly straightforward, featuring individual input and output registers with clocked D-type flip-flop, a preload capability which enables input data to be preloaded into the output registers, individual three-state output ports for the Extended Product (XTP) and Most Significant Product (MSP) and a Least Significant Product output (LSP) which is multiplexed with the Y input. The XIN and YIN data input registers may be specified through the use of the Two’s plement input (TC) as either a two’s plement or an unsigned magnitude, yielding a...
