Noninverting 3-State Buffer MC74VHC1G126, MC74VHC1GT126 The MC74VHC1G126 / MC74VHC1GT126 is a single gate noninverting 3 state buffer in tiny footprint packages. The MC74VHC1G126 has CMOS level input thresholds while the www.onsemi.com MC74VHC1GT126 has TTL level input thresholds. The internal circuit is composed of three stages, including a buffered 3state output which provides high noise immunity and stable output. MARKING The input structures provide protection when voltages up to 5.5 V DIAGRAMS are applied, regardless of the supply voltage. This allows the device to be used to interface 5 V circuits to 3 V circuits. The output structures SC88A also provide protection when V = 0 V and when the output voltage CC XX M DF SUFFIX exceeds V . These input and output structures help prevent device CC CASE 419A destruction caused by supply voltage input/output voltage mismatch, battery backup, hot insertion, etc. SC74A Features XXX M DBV SUFFIX Designed for 2.0 V to 5.5 V V Operation CC CASE 318BQ 3.5 ns t at 5 V (typ) PD Inputs/Outputs OverVoltage Tolerant up to 5.5 V 5 TSOP5 I Supports Partial Power Down Protection OFF XX M DT SUFFIX 5 Source/Sink 8 mA at 3.0 V CASE 483 1 1 Available in SC88A, SC74A, TSOP5, SOT553, SOT953 and UDFN6 Packages SOT553 XX M Chip Complexity < 100 FETs XV5 SUFFIX NLV Prefix for Automotive and Other Applications Requiring CASE 463B Unique Site and Control Change Requirements AECQ100 Qualified and PPAP Capable SOT953 P5 SUFFIX X M These Devices are PbFree, Halogen Free/BFR Free and are RoHS CASE 527AE 1 Compliant UDFN6 OE EN XM 1.45 x 1.0 Y A CASE 517AQ 1 Figure 1.
