1 / 9 page SN54LVCH245A, SN74LVCH245A OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS SCES008F – JULY 1995 - REVISED JUNE 1998 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D EPIC™ (Enhanced-Performance Implanted CMOS) Submicron Process D Typical VOLP (Output Ground Bounce) < 0.8 V at VCC = 3.3 V, TA = 25°C D Typical VOHV (Output VOH Undershoot) > 2 V at VCC = 3.3 V, TA = 25°C D Power Off Disables Outputs, Permitting Live Insertion D ESD Protection Exceeds 2000 V Per MIL-STD-883, Method 3015; Exceeds 200 V Using Machine Model (C = 200 pF, R = 0) D Latch-Up Performance Exceeds 250 mA Per JESD 17 D Support Mixed-Mode Signal Operation on All Ports (5-V Input/Output Voltage With 3.3-V VCC) 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), and Thin Shrink Small-Outline (PW) Packages, Ceramic Flat (W) Package, Ceramic Chip Carriers (FK), and DIPs (J) description The SN54LVCH245A octal bus transceiver is designed for 2.7-V to 3.6-V VCC operation and the SN74LVCH245A octal bus transceiver is designed for 1.65-V to 3.6-V VCC operation. These devices are designed for asynchronous communication between data buses. These 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. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment. 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. Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level. The SN54LVCH245A is characterized for operation over the full military temperature range of –55 °C to 125°C. The SN74LVCH245A is characterized for operation from –40 °C to 85°C.
