These 16-bit buffers/drivers SN74LVTH16541 are designed specifically for low-voltage (3.3-V) V_CCoperation, but with thecapability to provide a TTL interface to a 5-V system environment.
These devices are noninverting 16-bit buffers composed of two 8-bit sections with separate output-enablesignals. For either 8-bit buffer section, the two output-enable (1OE1 and 1OE2 or 2OE1 and 2OE2) inputs mustbe low for the corresponding Y outputs to be active. If either output-enable input is high, the outputs of that 8-bitbuffer section are in the high-impedance state.
When V_CC is between 0 and 1.5 V, the devices are in the high-impedance state during power up or power down.
About SN74LVTH16541, to ensure the high-impedance state above 1.5 V, OE should be tied to V_CCthrough a pullup resistor;the minimum value of the resistor is determined by the current-sinking capability of the driver.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
These devices SN74LVTH16541 are fully specified for hot-insertion applications using I  and power-up 3-state. The I  circuitryoff offdisables 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.
The SN54LVTH16541 is characterized for operation over the full military temperature range of 55°C to 125°C.The SN74LVTH16541 is characterized for operation from 40°C to 85°C.
