2.5 V / 3.3 V 20位缓冲器/带3态输出驱动程序 2.5-V/3.3-V 20-BIT BUFFERS/DRIVERS WITH 3-STATE OUTPUTS
The "ALVTH162827 devices are 20-bit buffers/line drivers designed for 2.5-V or 3.3-V VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.
The devices are composed of two 10-bit sections with separate output-enable signals. For either 10-bit buffer section, the two output-enable 1OE1\ and 1OE2\, or 2OE1\ and 2OE2\\\\ inputs must be low for the corresponding Y outputs to be active. If either output-enable input is high, the outputs of that 10-bit buffer section are in the high-impedance state.
When VCC is between 0 and 1.2 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.2 V, OE\ should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
All outputs are designed to sink up to 12 mA, and include equivalent 30- resistors to reduce overshoot and undershoot.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN54ALVTH162827 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALVTH162827 is characterized for operation from -40°C to 85°C.
