SN74ABTH245

SN54ABTH245, SN74ABTH245 OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS SCBS663D – APRIL 1996 – REVISED SEPTEMBER 1999 D State-of-the-Art EPIC-ΙΙB™ BiCMOS Design Significantly Reduces Power Dissipation D Latch-Up Performance Exceeds 500 mA Per JESD 17 D Typical VOLP (Output Ground Bounce) < 1 V at VCC = 5 V, TA = 25°C D Ioff and Power-Up 3-State Support Hot Insertion D High-Drive Outputs (–32-mA IOH, 64-mA IOL) D Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors 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), Plastic (N) and Ceramic (J) DIPs, and Ceramic Flat (W) Package description These octal bus transceivers 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 SN54ABTH245 . . . J OR W PACKAGE SN74ABTH245 . . .
