The MC74VHC1G126 / MC74VHC1GT126 is a single gate

noninverting 3?state buffer in tiny footprint packages. The

MC74VHC1G126 has CMOS?level input thresholds while the

MC74VHC1GT126 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. 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.
