Single 2-Input NOR Gate with Open Drain Output MC74VHC1G03, MC74VHC1GT03 The MC74VHC1G03 / MC74VHC1GT03 is a 2input NOR Gate with an open drain output in tiny footprint packages. www.onsemi.com The input structures provide protection when voltages up to 5.5 V MARKING are applied, regardless of the supply voltage. This allows the device to DIAGRAMS 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 CC SC88A XX M DF SUFFIX destruction caused by supply voltage input/output voltage mismatch, CASE 419A battery backup, hot insertion, etc. Features Designed for 2.0 V to 5.5 V V Operation CC SC74A XXX M 3.5 ns t at 5 V (typ) DBV SUFFIX PD CASE 318BQ Inputs/Outputs OverVoltage Tolerant up to 5.5 V I Supports Partial Power Down Protection OFF 5 Source/Sink 8 mA at 3.0 V TSOP5 XX M Available in SC88A, SC74A, TSOP5, SOT553, SOT953 and 5 DT SUFFIX UDFN6 Packages CASE 483 1 1 Chip Complexity < 100 FETs NLV Prefix for Automotive and Other Applications Requiring SOT553 Unique Site and Control Change Requirements AECQ100 XX M XV5 SUFFIX Qualified and PPAP Capable CASE 463B These Devices are PbFree, Halogen Free/BFR Free and are RoHS Compliant SOT953 P5 SUFFIX X M A 1 CASE 527AE Y 1 B Figure 1.
