DATA SHEET www.onsemi.com MARKING Single 2-Input OR Gate DIAGRAMS MC74VHC1G32, SC88A XX M DF SUFFIX MC74VHC1GT32 CASE 419A The MC74VHC1G32 / MC74VHC1GT32 is a single 2input OR Gate in tiny footprint packages. The MC74VHC1G32 has SC74A CMOS level input thresholds while the MC74VHC1GT32 has XXX M DBV SUFFIX TTLlevel thresholds. CASE 318BQ The input structures provide protection when voltages up to 5.5 V are applied, regardless of the supply voltage. This allows the device to 5 be used to interface 5 V circuits to 3 V circuits. The output structures TSOP5 also provide protection when V = 0 V and when the output voltage CC XX M DT SUFFIX 5 exceeds V . These input and output structures help prevent device CC CASE 483 1 destruction caused by supply voltage input/output voltage mismatch, 1 battery backup, hot insertion, etc. 5 Features XXXAYW Designed for 2.0 V to 5.5 V V Operation CC 3.7 ns t at 5 V (typ) 1 PD Inputs/Outputs OverVoltage Tolerant up to 5.5 V I Supports Partial Power Down Protection OFF SOT953 P5 SUFFIX X M Source/Sink 8 mA at 3.0 V CASE 527AE 1 Available in SC88A, SC74A, TSOP5, SOT953 and UDFN6 Packages UDFN6 Chip Complexity < 100 FETs 1.45 x 1.0 XM 1 CASE 517AQ NLV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements AECQ100 UDFN6 Qualified and PPAP Capable 1.2 x 1.0 X M These Devices are PbFree, Halogen Free/BFR Free and are RoHS CASE 517AA 1 Compliant UDFN6 A 1.0 x 1.0 X M 1 Y CASE 517BX 1 B Figure 1.
