The SN74LVCH16541A is a noninverting 16-bit buffer posed of two 8-bit sections with separate output-enable signals. For either 8-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 8-bit buffer section are in the high-impedance state. To ensure the high-impedance state during power up or power down, 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. - 40°C to 85°C ORDERING INFORMATION PACKAGE (1) ORDERABLE PART NUMBER SSOP - DL Tube Tape and reel SN74LVCH16541ADL SN74LVCH16541ADLR...
