1 / 16 page SN54ABT827, SN74ABT827 10BIT BUFFERS/DRIVERS WITH 3STATE OUTPUTS SCBS159E − JANUARY 1991 − REVISED APRIL 2005 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D State-of-the-Art EPIC-ΙΙB BiCMOS Design Significantly Reduces Power Dissipation D Flow-Through Architecture Optimizes PCB Layout D Latch-Up Performance Exceeds 500 mA Per JEDEC Standard JESD-17 D Typical VOLP (Output Ground Bounce) < 1 V at VCC = 5 V, TA = 25°C D High-Impedance State During Power Up and Power Down D High-Drive Outputs (−32-mA IOH, 64-mA IOL) D Package Options Include Plastic Small-Outline (DW), Shrink Small-Outline (DB), and Thin Shrink Small-Outline (PW) Packages, Ceramic Chip Carriers (FK), and Plastic (NT) and Ceramic (JT) DIPs description These 10-bit buffers or bus drivers provide a high-performance bus interface for wide data paths or buses carrying parity. 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 ten outputs are in the high-impedance state. The ’ABT827 provides true data at the outputs. When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 2.1 V, 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 SN54ABT827 is characterized for operation over the full military temperature range of −55 °C to 125°C. The SN74ABT827 is characterized for operation from −40 °C to 85°C.
