DESCRIPTION
TC, ACC, and SUB controls are latched on the rising edge of the logical OR of CLK A and CLK B. TC specifies the input as two’s complement (TC HIGH) or unsigned magnitude (TC LOW). RND, when HIGH, adds ‘1’ to the most significant bit position of the least significant half of the product. Subsequent truncation of the 16 least The LMA1010 and LMA2010 produce significant bits produces a result the 32-bit product of two 16-bit numbers. correctly rounded to 16-bit preciThe results of a series of multiplications sion. may be accumulated to form the sum of products.

The L MA1010 a nd L MA2010 a re high-speed, low power 16-bit multiplier-accumulators. The LMA1010 and LMA2010 are functionally identical; they differ only in packaging. Full military ambient temperature range operation is achieved with advanced CMOS technology. The LMA1010/2010 output register (accumulator register) is divided into three independently controlled sections. The least significant result (LSR) and most significant result (MSR) registers are 16 bits in length. The extended result register (XTR) is 3 bits long. The output signals R15-0 and input signals B15-0 share the same bidirectional pins. Each output register has an independent output enable control. In addition to providing three-state control of the output buffers, when OEX, OEM, or OEL are HIGH and PREL is HIGH, data can be preloaded via the bidirectional output pins into the respective output registers. Data present on the output pins is latched on the rising edge of CLK R. The interrelation of PREL and the enable controls is summarized in Table 1.

Exposure to maximum rating conditions for extended periods may affect reliability. 11. For the tENA test, the transition is measured to the 1.5 V crossing point with datasheet loads. For the tDIS test, the transition is measured to the ±200mV level from the measured steady-state output voltage with ±10mA loads. The balancing voltage, V TH , is set at 3.5 V for Z-to-0 and 0-to-Z tests, and set at 0 V for Zto-1 and 1-to-Z tests. 12. These parameters are only tested at the high temperature extreme, which is the worst case for leakage current.
