description/ordering information

These octal buffers/drivers are designed

specifically for low-voltage (3.3-V) VCC operation,

with the capability to provide a TTL interface to a

5-V system environment.

The ’LVTH241 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.
