Noninverting 3-State Buffer

The MC74VHC1G125 / MC74VHC1GT125 is a single non?inverting 3?state buffer in tiny footprint packages. The MC74VHC1G125 has CMOS?level input thresholds while the MC74VHC1GT125 has TTL?level input thresholds.

The internal circuit is composed of three stages, including a buffered 3?state output which provides high noise immunity and stable output. 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. The 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.
