Pin assignment is for Dual-in-Line Package. For PLCC pin assignment, see the Pin Conversion Tables on page 6-11 of the Motorola MECL Data Book (DL122/D).
NOTE: Each MECL 10H series circuit has been designed to meet the dc specifications shown in the test table, after thermal equilibrium has been established. The circuit is in a test socket or mounted on a printed circuit board and transverse air flow greater than 500 Ifpm is maintained. Outputs are terminated through a 50-ohm resistor to -2.0 volts.

TYPICAL APPLICATIONS
The MC10H179 is a high-speed, low-power, standard MECL complex function that is designed to perform the look-ahead carry function. This device can be used with the MC10H181 4-bit ALU directly, or with the MC10H180 dual arithmetic unit in any computer, instrumentation or digital communication application requiring high speed arithmetic operation on long words. When used with the MC10H181, the MC10H179 performs a second order or higher look-ahead. Figure 2 shows a 16-bit look-ahead carry arithmetic unit. Second order carry is valuable for longer binary words. As an example, addition of two 32-bit words is improved from 30 nanoseconds with ripple-carry techniques. A block diagram of a 32-bit ALU is shown in Figure 1. The MC10H179 may also be used in many other applications. It can, for example, reduce system package count when used to generate functions of several variables.
