FEATURES
DESCRIPTION
The 74LV126 is a low-voltage Si-gate CMOS device that is pin and
function compatible with 74HC/HCT126.
• Wide operating voltage: 1.0 to 5.5 V
• Optimized for low voltage applications: 1.0 to 3.6 V
The 74LV126 consists of four non-inverting buffers/line drivers with
3-state outputs. The 3-state outputs (nY) are controlled by the output
enable input (nOE). A LOW at nOE causes the outputs to assume a
high impedance OFF-state.
• Accepts TTL input levels between V = 2.7 V and V = 3.6 V

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
DC ELECTRICAL CHARACTERISTICS
Over recommended operating conditions, voltages are referenced to GND (ground = 0 V)
