Component qualification in accordance with JEDEC and industry  
standards to ensure reliable operation over an extended  
temperature range. This includes, but is not limited to, Highly  
Accelerated Stress Test (HAST) or biased 85/85, temperature  
cycle, autoclave or unbiased HAST, electromigration, bond  
intermetallic life, and mold compound life. Such qualification  
testing should not be viewed as justifying use of this component  
beyond specified performance and environmental limits.

description/ordering information

operation, with the capability to  
CC  
The SN74LVTH241 is organized as two 4-bit line drivers with separate output-enable (1OE, 2OE) inputs. When  
1OE is low or 2OE is high, the device passes noninverted data from the A inputs to the Y outputs. When 1OE  
is high or 2OE is low, the outputs are in the high-impedance state.  
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors  
with the bus-hold circuitry is not recommended.  
When V  
is between 0 and 1.5 V, the device is in the high-impedance state during power up or power down.  
CC  
However, to ensure the high-impedance state above 1.5 V, OE should be tied to V  
through a pullup resistor  
CC  
and OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by  
the current-sinking/current-sourcing capability of the driver.  
This device is fully specified for hot-insertion applications using I and power-up 3-state. The I circuitry  
off  
off  
disables the outputs, preventing damaging current backflow through the device when it is powered down. The  
power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down,  
which prevents driver conflict.
