Hldtl 126 in a transistor transistor logic ttl if the

126. in a transistor-transistor-logic
(TTL), if the base collector junction of a
transistor is clamped with a Schottky-
diode it becomes Schottky TTL. What is the
significance of having this diode?
127. PMOS are generally supplied with a
voltage up to
15 V
128. NMOS can be interlaced to CMOS by
providing a
pull-up resistor
129. a digital IC whose output transistor
has no internal pull-up resistor.
Open-collector configuration
130. in digital ICs, such as buffers and
registers, what output configuration is
used if they are intended for “busing” ?
tri-state output
131. in TTL ICs, which input
configurations gives a high-input
impedance at both logic states (HIGH and
LOW state)?
Substrate pnp input
132. what is the purpose of internal
clamping diodes at the input of a logic
circuit?
To minimize negative ringing effects
133. in TTL ICs with more than one gates
available, sometimes not all gates are
used. How will you handle these unused
gates?
Force the output to go HIGH
134. how will you handle unused inputs in
a logic gate/logic IC?
Pull them up or down, depending on circuit
function
