http://www.interfacebus.com/voltage_threshold.html WebApr 12, 2024 · The actual output voltage depends on the output current. For heavily loaded outputs, the output levels might vary of 0.5V or more!), still the minimum high-level input voltage for a TTL is 2V. Similarly, if not too much heavily loaded, the low-level output voltage of a CMOS is lower than the maximum low-level TTL input voltages. high pating jobs requires no degree

TTL And LVTTL Voltage Levels - Euresys

WebThe HCT and ACT CMOS families are designed with a low threshold similar to TTL for compatability (since bipolar TTL outputs do not swing all the way to +V). 24mA Sink/Source drive current. ACT has TTL compatible inputs. Min high level voltage = 2V so these can be used to interface 3V3 IC’s to 5V IC’s. WebAs you can see above, these relationships match for 5 V TTL and 3.3 V LVTTL. True TTL outputs do not actually output a 5 V high signal, but something near 3.3 V, so they would not overload a 3.3 V input. If your 5 V signals are not TTL but CMOS, you could use something like the TXS0108E. Emrys Maier over 4 years ago in reply to faussat thibault.
