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-Ω 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.
●• Output Ports Have Equivalent 25-Ω Series Resistors, So No External Resistors Are Required
●• State-of-the-Art EPIC-ΙΙB BiCMOS Design Significantly Reduces Power Dissipation
●• Latch-Up Performance Exceeds 500 mA Per JEDEC Standard JESD-17
●• Typical VOLP (Output Ground Bounce) < 1 V at VCC = 5 V, TA = 25°C
●• Typical VOLV (Output Undershoot) < 0.5 V at VCC = 5 V, TA = 25°C
●• Package Options Include Plastic Small-Outline (DW) Package and Ceramic Chip Carriers (FK) and DIPs (JT)
