Single Non-Inverting Buffer with Open Drain Output
MC74VHC1G07, MC74VHC1GT07
The MC74VHC1G07 / MC74VHC1GT07 is a single non−inverting buffer with open drain output in tiny footprint packages. The MC74VHC1G07 has CMOS−level input thresholds while the MC74VHC1GT07 has TTL−level input thresholds.
The input structures provide protection when voltages up to 5.5 V are applied, regardless of the supply voltage. This allows the device to be used to interface 5 V circuits to 3 V circuits. Some output structures also provide protection when VCC = 0 V and when the output voltage exceeds VCC. These input and output structures help prevent device destruction caused by supply voltage − input/output voltage mismatch, battery backup, hot insertion, etc.
