MC74VHC1G126XV5T2G中文资料安森美半导体数据手册PDF规格书

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.
