mAat 3-VVCC for External Pullup/Pulldown Resistors•
Control Inputs VIH/VIL Levels Are Referenced – 2000-V Human-Body Model (A114-A)to VCCB Voltage – 200-V Machine Model (A115-A)•
If EitherVCC InputIsat GND, Both Ports Arein 1000-V Charged-Device Model (C101)the High-Impedance StateThis 32-bit noninverting bus transceiver uses two separate configurable power-supply rails. TheA portis
designedto track VCCA. VCCA accepts any supply voltage from 1.4Vto 3.6V. TheB portis designedto track
VCCB. VCCB accepts any supply voltage from 1.4Vto 3.6V. This allows for universal low-voltage bidirectional
translation between anyof the 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.
The SN74AVCBH324245is designed for asynchronous communication between data buses. The device
transmits data from theA busto theB busor from theB busto theA bus, depending on the logic levelat the
direction-control (DIR) input. The output-enable (OE) inputis usedto disable the outputs,so the buses effectively
are isolated.
The SN74AVCBH324245is designedso that the control pins (1DIR, 2DIR, 1OE, and 2OE) are suppliedby VCCB.
Active bus-hold circuitryis providedto hold unusedor floating data inputsata valid logic level. Useof pullupor
pulldown resistors with the bus-hold circuitryis not recommended. ensure the high-impedance state during powerupor power down, OE should be tiedto VCCB througha pullup
resistor; the minimum valueof the resistoris determinedby the current-sinking capabilityof the driver.
This deviceis fully specified for partial-power-down applications using Ioff. TheIoff circuitry disables the outputs,
preventing damaging current backflow through the device whenitis powered down.If either VCC inputisat GND,
both ports arein the high-impedance state.
