WebNov 29, 2024 · Although in maximum cases it is a weak pull-up, means the current is very low. Often, we need pull up for more than 2 or 3 digital input-output pins, in such case a resistor network is used. It is easy to integrate and provide lower pin counts. It is called a resistor network or SIP resistors. This is the symbol of the resistor net. Webresistor in the TTL output stage, higher-than-normal currents called current spikes flow when TTL outputs are switched. These are similar to the current spikes that occur when high-speed CMOS outputs switch. So far we have shown the input signals to a TTL gate as ideal voltage sources.
