DATA SHEET www.onsemi.com MARKING Buffer DIAGRAMS SC88A MC74VHC1G50, XX M DF SUFFIX CASE 419A MC74VHC1GT50 The MC74VHC1G50 / MC74VHC1GT50 is an advanced high SC74A XXX M DBV SUFFIX speed CMOS buffer in tiny footprint packages. The MC74VHC1G50 CASE 318BQ has CMOS level input thresholds while the MC74VHC1GT50 has TTL level input thresholds. 5 The input structures provide protection when voltages up to 5.5 V 5 5 1 are applied, regardless of the supply voltage. This allows the device to XXXAYW XX M TSOP5 be used to interface 5 V circuits to 3 V circuits. The output structures DT SUFFIX also provide protection when V = 0 V and when the output voltage CC CASE 483 1 1 exceeds V . These input and output structures help prevent device CC destruction caused by supply voltage input/output voltage mismatch, SOT553 XX M battery backup, hot insertion, etc. XV5 SUFFIX CASE 463B Features Designed for 2.0 V to 5.5 V V Operation SOT953 CC P5 SUFFIX X M 3.5 ns t at 5 V (typ) PD CASE 527AE 1 Inputs/Outputs OverVoltage Tolerant up to 5.5 V I Supports Partial Power Down Protection OFF UDFN6 1.45 x 1.0 XM Source/Sink 8 mA at 3.0 V 1 CASE 517AQ Available in SC88A, SC74A, TSOP5, SOT553, SOT953 and UDFN6 Packages UDFN6 1.2 x 1.0 X M Chip Complexity < 100 FETs CASE 517AA 1 NLV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements AECQ100 UDFN6 Qualified and PPAP Capable 1.0 x 1.0 X M CASE 517BX These Devices are PbFree, Halogen Free/BFR Free and are RoHS 1 Compliant XX = Specific Device Code M = Date Code* = PbFree Package 1 A Y (Note: Microdot may be in either location) *Date Code orientation and/or position may Figure 1.
