74LV126
FEATURES · Wide operating voltage: 1.0 to 5.5 V · Optimized for low voltage applications: 1.0 to 3.6 V · Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V · Typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V,
Tamb = 25°C
DESCRIPTION
The 74LV126 is a low-voltage Si-gate CMOS device that is pin and function compatible with 74HC/HCT126. 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.
· Typical VOHV (output VOH undershoot) > 2 V at VCC = 3.3 V,
Tamb = 25°C
· Output capability: bus driver · ICC category: MSI QUICK REFERENCE DATA

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.
