74LVT126
3.3 V quad buffer; 3-state
The 74LVT126 is a quad buffer/line driver with 3-state outputs controlled by the output enable inputs (nOE). A LOW on nOE causes the outputs to assume a high impedance OFF-state. Bus hold data inputs eliminate the need for external pull-up resistors to define unused inputs. This device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.
Features and benefits
Quad bus interface
3-state buffers
Wide supply voltage range from 2.7 to 3.6 V
Overvoltage tolerant inputs to 5.5 V
BiCMOS high speed and output drive
Output capability: +64 mA and -32 mA
Direct interface with TTL levels
Input and output interface capability to systems at 5 V supply
Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs
Live insertion and extraction permitted
No bus current loading when output is tied to 5 V bus
Power-up 3-state
IOFF circuitry provides partial Power-down mode operation
Latch-up performance exceeds 500 mA per JESD 78 Class II Level B
