Product Overview MC74VHC1GT126: Single Non-Inverting Buffer, TTL Level For complete documentation, see the data sheet Product Description The MC74VHC1GT126 is a single gate noninverting 3-state buffer fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. The MC74VHC1GT126 requires the 3-state control input (OE(bar)) to be set Low to place the output into the high impedance state. The device input is compatible with TTL-type input thresholds and the output has a full 5V CMOS level output swing. The input protection circuitry on this device allows overvoltage tolerance on the input, allowing the device to be used as a logic-level translator from 3.0V CMOS logic to 5.0V CMOS Logic or from 1.8V CMOS logic to 3.0V CMOS Logic while operating at the high-voltage power supply. The MC74VHC1GT126 input structure provides protection when voltages up to 7V are applied, regardless of the supply voltage. This allows the MC74VHC1GT126 to be used to interface 5V circuits to 3V circuits. The output structures also provide protection when VCC = 0V. These input and output structures help prevent device destruction caused by supply voltage - input/output voltage mismatch, battery backup, hot insertion, etc. Features • • • • • • • • • High Speed: tPD = 3.5ns (Typ) at V CC = 5V Low Power Dissipation: ICC = 1µA (Max) at TA = 25°C TTL-Compatible Inputs: VIL = 0.8V; VIH = 2.0V CMOS-Compatible Outputs: VOH > 0.8VCC ; VOL < 0.1VCC @Load Power Down Protection Provided on Inputs and Outputs Balanced Propagation Delays Pin and Function Compatible with Other Standard Logic Families Chip Complexity: FETs = 62; Equivalent Gates = 16 Pb-Free Packages are Available Part Electrical Specifications Product M74VHC1GT126DF1G Compliance Status Channels Output VCC Min (V) VCC Max (V) tpd Max (ns) IO Max (mA) Package Type Pb-free Active 1 3-State 3 5.5 7.5 8 SC-88A-5 / SC-70-5 / SOT-323-5 Active 1 3-State 3 5.5 7.5 8 SC-88A-5 / SC-70-5 / SOT-323-5 Active 1 3-State 3 5.5 7.5 8 TSOP-5 / SOT-23-5 Active 1 3-State 3 5.5 7.5 8 SC-88A-5 / SC-70-5 / SOT-323-5 Active 1 3-State 3 5.5 7.5 8 SC-88A-5 / SC-70-5 / SOT-323-5 Active 1 3-State 3 5.5 7.5 8 TSOP-5 / SOT-23-5 Halide free M74VHC1GT126DF2G Pb-free Halide free M74VHC1GT126DT1G Pb-free Halide free NLVVHC1GT126DF1G AEC Qualified PPAP Capable Pb-free Halide free NLVVHC1GT126DF2G AEC Qualified PPAP Capable Pb-free Halide free NLVVHC1GT126DT1G AEC Qualified PPAP Capable Pb-free Halide free For more information please contact your local sales support at www.onsemi.com Created on: 6/30/2016
