资 源 简 介

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