Features, Applications

State-of-the-Art EPIC-B TM BiCMOS Design Significantly Reduces Power Dissipation ESD Protection Exceeds 2000 V Per MIL-STD-883, Method 3015; Exceeds 200 V Using Machine Model = 200 pF, = 0) Latch-Up Performance Exceeds 500 mA Per JEDEC Standard JESD-17 Typical VOLP (Output Ground Bounce) V at VCC = 25C High-Drive Outputs (32-mA IOH, 64-mA IOL) Package Options Include Plastic Small-Outline (DW), Shrink Small-Outline (DB), and Thin Shrink Small-Outline (PW) Packages, Ceramic Chip Carriers (FK), Plastic (N) and Ceramic (J) DIPs, and Ceramic Flat (W) Package


The 'ABT540 octal buffers and line drivers are ideal for driving bus lines or buffer memory address registers. The devices feature inputs and outputs on opposite sides of the package that facilitate printed circuit board layout. The 3-state control gate a 2-input AND gate with active-low inputs so that if either output-enable or OE2) input is high, all corresponding outputs 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. The SN54ABT540 is characterized for operation over the full military temperature range to 125C. The SN74ABT540 is characterized for operation from to 85C.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. The package thermal impedance is calculated in accordance with EIA/JEDEC Std JESD51, except for through-hole packages, which use a trace length of zero.

* On products compliant to MIL-PRF-38535, this parameter does not apply. All typical values are at VCC 5 V. Not more than one output should be tested at a time, and the duration of the test should not exceed one second. This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.
