description

These octal buffers/drivers are designed
specifically for low-voltage (3.3-V) V
with the capability to provide a TTL interface to a
5-V system environment.

The ’L VTH241 devices are organized as two 4-bit
line drivers with separate output-enable (1OE
2OE) inputs. When 1OE

is low or 2OE is high, the
devices pass 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
However, to ensure the high-impedance state above 1.5 V, OE

is between 0 and 1.5 V , the devices are in the high-impedance state during power up or power down.

CC

should be tied to VCC through a pullup resistor
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.

These devices are fully specified for hot-insertion applications using I

and power-up 3-state. The I

off

disables the outputs, preventing damaging current backflow through the devices when they are 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.

†

Stresses beyond those listed under “absolute maximum ratings” 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.

NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.

2. This current flows only when the output is in the high state and VO > VCC.

3. The package thermal impedance is calculated in accordance with JESD 51-7.
