DATA SHEET www.onsemi.com MARKING Noninverting 3-State Buffer DIAGRAMS MC74VHC1G125, SC88A XX M DF SUFFIX MC74VHC1GT125 CASE 419A The MC74VHC1G125 / MC74VHC1GT125 is a single non inverting 3 state buffer in tiny footprint packages. The SC74A MC74VHC1G125 has CMOS level input thresholds while the XXX M DBV SUFFIX MC74VHC1GT125 has TTL level input thresholds. CASE 318BQ The internal circuit is composed of three stages, including a buffered 3state output which provides high noise immunity and stable output. 5 TSOP5 The input structures provide protection when voltages up to 5.5 V XX M 5 DT SUFFIX are applied, regardless of the supply voltage. This allows the device to CASE 483 1 be used to interface 5 V circuits to 3 V circuits. The output structures 1 also provide protection when V = 0 V and when the output voltage CC exceeds V . These input and output structures help prevent device CC SOT953 destruction caused by supply voltage input/output voltage mismatch, P5 SUFFIX X M CASE 527AE battery backup, hot insertion, etc. 1 Features UDFN6 Designed for 2.0 V to 5.5 V V Operation 1.45 x 1.0 CC XM 1 CASE 517AQ 3.5 ns t at 5 V (typ) PD Inputs/Outputs OverVoltage Tolerant up to 5.5 V UDFN6 I Supports Partial Power Down Protection OFF 1.2 x 1.0 X M Source/Sink 8 mA at 3.0 V CASE 517AA 1 Available in SC88A, SC74A, TSOP5, SOT953 and UDFN6 Packages UDFN6 1.0 x 1.0 X M Chip Complexity < 100 FETs CASE 517BX 1 NLV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements AECQ100 XX = Specific Device Code Qualified and PPAP Capable M = Date Code* These Devices are PbFree, Halogen Free/BFR Free and are RoHS = PbFree Package Compliant (Note: Microdot may be in either location) OE *Date Code orientation and/or position may EN Y vary depending upon manufacturing location.
