2. Answer the following questions about the TTL gate shown: www 4k 1.6k www INPUTS Ꭺ Ꮕ www 4k B www 1k www. 130 Vcc = +5V OUTPUT OF a. Make a table that states whether each of the transistors Q1 ... Q6 is on or off for all combinations of HI and LOW inputs A and B. b. What logic function does this gate represent? c. Approximately, what current flows in an input line when the input is HIGH? What flows when the input is LOW? d. Without any load, the voltage when the output is HIHG is less than 5 volts. Explain why, and what voltage is it and why it is that voltage. e. If the output is HI, then the output current is 1.5 mA, what would the output voltage be? Explain and/or show a calculation that supports this.
