SN74ABTR2245

SN54ABTR2245, SN74ABTR2245 OCTAL TRANSCEIVERS AND LINE/MEMORY DRIVERS WITH 3-STATE OUTPUTS SCBS680A – MARCH 1997 – REVISED MAY 1997 D Outputs Have Equivalent 25-Ω Series Resistors, So No External Resistors Are Required D State-of-the-Art EPIC-ΙΙB™ BiCMOS Design Significantly Reduces Power Dissipation D High-Impedance State During Power Up and Power Down D Latch-Up Performance Exceeds 500 mA Per JEDEC Standard JESD-17 D ESD Protection Exceeds 2000 V Per MIL-STD-833, Method 3015; Exceeds 200 V Using Machine Model (C = 200 pF, R = 0) D Typical VOLP (Output Ground Bounce) < 1 V at VCC = 5 V, TA = 25°C D Package Options Include Plastic Small-Outline (DW), Shrink Small-Outline (DB), Thin Shrink Small-Outline (PW), and Thin Very Small-Outline (DGV) Packages, Ceramic Chip Carriers (FK), and Plastic (N) and Ceramic (J) DIPs description These octal transceivers and line drivers are designed for asynchronous communication between data buses. The devices transmit data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so the buses are effectively isolated. A8 GND B8 SN54ABTR2245 . . . J PACKAGE SN74ABTR2245 . . .
