MC74VHC1GT126
Noninverting Buffer /
CMOS Logic Level Shifter
with LSTTL−Compatible Inputs
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) 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 5 V 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 3.0 V
CMOS logic to 5.0 V CMOS Logic or from 1.8 V CMOS logic to 3.0 V
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 5 V circuits to 3 V
circuits. The output structures also provide protection when VCC = 0 V.
These input and output structures help prevent device destruction caused
by supply voltage − input/output voltage mismatch, battery backup, hot
insertion, etc.
High Speed: tPD = 3.5 ns (Typ) at VCC = 5 V
Low Power Dissipation: ICC = 1 mA (Max) at TA = 25°C
TTL−Compatible Inputs: VIL = 0.8 V; VIH = 2.0 V
CMOS−Compatible Outputs: VOH > 0.8 VCC; VOL < 0.1 VCC @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

6. CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load.
Average operating current can be obtained by the equation: ICC(OPR) = CPD  VCC  fin + ICC / 4 (per buffer). CPD is used to determine the
no−load dynamic power consumption; PD = CPD  VCC2  fin + ICC  VCC.
