MC74VHC1G126,
MC74VHC1GT126
Noninverting 3-State Buffer
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. The output structures

also provide protection when V = 0 V and when the output voltage
CC
exceeds V . These input and output structures help prevent device

destruction caused by supply voltage − input/output voltage mismatch,
battery backup, hot insertion, etc.
