SN74ABT5402A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

These 12-bit buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The 3-state control gate is a 2-input AND gate with active-low inputs so that if either output-enable (OE1\\ or OE2\\) input is high, all 12 outputs are in the high-impedance state. The outputs, which are designed to source or sink up to 12 mA, include equivalent 25- series resistors to reduce overshoot and undershoot. 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. The SN54ABT5402A is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABT5402A is characterized for operation from -40°C to 85°C.
