SN74ABT16541A数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 Description

The SN54ABT16541 and SN74ABT16541A are noninverting 16-bit buffers composed of two 8-bit sections with separate output-enable signals. For either 8-bit buffer section, the two output-enable (1 and 1 or 2and 2) inputs must both 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,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.The SN54ABT16541 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABT16541A is characterized for operation from -40°C to 85°C.
