Logical Design of Digital Systems Experiment 1: data-traffic in digital circuits 1.6 Data Transfer via a Bus It is often necessary to transfer 8- or 16-bit words in 4-bit sections via the same conduction for processing and administering data in digital technique. This principle is e.g. used concerning input and output units for systems of processors. The following circuit is supposed to be simulated. The components that are used are a RAM (74170, a 4x4 bit registers with open-collector) and two 4-bit D-type-registers with a tristate output 74LS173A. Figure 1.11: Data transfer via a bus Q22: Why are the pins 9, 10 (

in the circuit) as well as in the circuit) connected with each other? Which functions do the inputs have? Q23: What is the task of pin 15 at the register? 14 of 61
