This 16-bit (dual-octal) noninverting bus transceiver is designed for 1.65-Vto 3.6-V VCC operation.
The SN74LVCR16245A device is designed for asynchronous communication betweendata buses. All inputs and outputs have equivalent 26-Ω resistors that will slowthe edges of the output and reduce switching noise caused by long capacitiveetch runs or cables.
This device can be used as two 8-bit transceivers or one 16-bit transceiver.Active bus-hold circuitry holds unused or undriven data inputs at a valid logicstate.
Member of the Texas Instruments Widebus Family
Operates From 1.65 V to 3.6 V
Inputs Accept Voltages to 5.5 V
Max tpd of 4.8 ns at 3.3 V
Typical VOLP (Output Ground Bounce) <0.8 V atVCC = 3.3 V, TA = 25°D
Typical VOHV (Output VOH Undershoot) >2 V at VCC = 3.3 V, TA = 25°C
Supports Mixed-Mode Signal Operation on All Ports (5-V Input/Output Voltage With 3.3-V VCC)
All Inputs and Outputs Have Equivalent 26-Ω Series Resistors, So No External Resistors Are Required
Ioff Supports Live Insertion, Partial-Power-Down Mode, and Back-Drive Protection
