MC74VHC1G126

DATA SHEET www.onsemi.com Noninverting 3-State Buffer MC74VHC1G126, MC74VHC1GT126 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. Features Designed for 2.0 V to 5.5 V VCC Operation 3.5 ns tPD at 5 V (typ) Inputs/Outputs Over−Voltage Tolerant up to 5.5 V IOFF Supports Partial Power Down Protection Source/Sink 8 mA at 3.0 V Available in SC−88A, SC−74A, TSOP−5, SOT−553, SOT−953 and UDFN6 Packages Chip Complexity < 100 FETs −Q Suffix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant OE EN Y A Figure 1.
