Unused TTL inputs should never be left open. Depending on how their logic levels
will affect the operation you want from the device, unused inputs should always
be tied to either the +5v supply (logic 1) or to the circuit ground (logic 0). If an
input is left open ("floating"), then it can assume either logic level, and you literally
never know which state it's in.
What else can I help you with?
What should be done with the unused inputs of a TTL integrated circuit?
Unused ttl inputs would normally default to logic 1 if left floating. but these inputs could act as antennas under certain conditions and they could pick up noise which can cause the circuit to malfunction. it is better to tie unused inputs to Vcc through a 1k resistor (74LS, 74XX etc) or simply return the inputs to ground. for most other ttl families, the 1k resistor might not be required.- Stan (Nigeria)
What is a TTL-compatible output?
Compatibility in TTL means that the output of one TTL device can be used to drive the Input of the other TTL device , This because the low and high output window fit inside the low and high input window/profile TTL stand for Transistor Transistor Logic, so any voltage between 0 and 5 volt is compatible where any voltage between 3V and 5V is logic 1 and zero volt is logic 0
What is a TTL compatible output?
A: TTL gates operates on the premise of having +5 dc on the rail therefore the output will be in the range +5 volts. A cmos gate while similar to a TTL function is not really compatible since the output volts can be 12 volts or more. Besides that TTL gates require some input current for it to operate
Ttl logic family has an output state known as?
true and false
Why an open ttl gate behaves as a logic high input?
because TTL have a bias input setup to eliminate noise therefore the output will follow the logic one input if left open
Why is setting the TTL to a small number a bad Idea?
Because a TTL determines the maximum number of days the server will TTL of 0 means that the resource record should not be cached.
What is a TTL waveform?
A TTL waveform refers to the output signal of a Transistor-Transistor Logic (TTL) digital circuit, characterized by its distinct voltage levels representing binary states. Typically, a TTL high state is around 2.4 to 5 volts, while a low state is around 0 to 0.8 volts. The waveform transitions sharply between these levels, reflecting the rapid switching behavior of TTL circuits. TTL waveforms are used in various digital applications, including logic gates, microprocessors, and communication systems.
Why do TTl integrated circuits assume unconnected inputs to be at logic?
Unused ttl inputs would normally default to logic 1 if left floating. but these inputs could act as antennas under certain conditions and they could pick up noise which can cause the circuit to malfunction.
How can a ttl output from a receiver be used to switch a transistor on or off?
By choosing the type of transistor to meet your needs carefully. I assume what you're trying to do is feed beyond the ttl output's power capability? a JFET may be a good option. A simple amplifier circuit using a MOSFET may be all you need, and this might be more readily available.
Interfacing of ttl with cmos and cmos with ttl?

Which has a shorter propagation delay TTL or CMOS?
TTL
What is the full form of TTL?
TTL stands for Time To Live
