The 8021 processor scans the key matrix, converts switch closures to an 8-bit code and then transmits that code serially to the keyboard interface on the main system. It will also accept commands to turn indicator LEDs on or off. The 8021 was also used in the keyboards for the TRS-80 Model 12, 12B, 16, 16B and the Tandy 6000/6000HD. [6]
Size comparison of BJT transistor packages, from left to right: SOT-23, TO-92, TO-126, TO-3 3D model of TO-3 package. In electronics, TO-3 is a designation for a standardized metal semiconductor package used for power semiconductors, including transistors, silicon controlled rectifiers, and, integrated circuits.
The number of leads is always even. For 0.3 inch spacing, typical lead counts are 8, 14, 16, and 20; less common are 4, 6, 18, 24, and 28 lead counts. To have an even number of leads some DIPs have unused not connected (NC) [nb 1] leads to the internal chip, or are duplicated, e.g. two ground pins. For 0.6 inch spacing, typical lead counts are ...
The IEEE renewed the standard in the 1990s, but withdrew it from active support shortly thereafter. This document also has an ANSI document number, ANSI Y32.16-1975. This standard codified information from, among other sources, a United States military standard MIL-STD-16 which dates back to at least the 1950s in American industry.
The continuous time (CT) blocks are composed of an op-amp circuit and designated as ACBxx where xx is 00–03. The other type is the switch cap (SC) blocks, which allow complex analog signal flows and are designated by ASCxy where x is the row and y is the column of the analog block.

Through-hole technology uses holes drilled through the printed circuit board (PCB) for mounting the components. The component has leads that are soldered to pads on the PCB to electrically and mechanically connect them to the PCB. Three 14-pin (DIP14) plastic dual in-line packages containing IC chips.
