WebThe minimum output voltage is GND. Driver output : At high logic level, minimum (V OH) is 2.4V for LVTTL and TTL and maximum is Vcc which is 3.3 V for LVTTL and 5V for TTL. … Like DTL, TTL is a current-sinking logic since a current must be drawn from inputs to bring them to a logic 0 voltage level. The driving stage must absorb up to 1.6 mA from a standard TTL input while not allowing the voltage to rise to more than 0.4 volts. The output stage of the most common TTL gates is specified to function correctly when driving up to 10 standard input stages (a fanout of 10). TTL inputs are sometimes simply left floating to provide a logical "1", though thi…
