74VCXH16245
LowVoltage 1.8/2.5/3.3V
16Bit Transceiver
With 3.6 VTolerant Inputs and Outputs
(3State, NonInverting)
The 74VCXH16245 is an advanced performance, noninverting
16bit transceiver. It is designed for very highspeed, very lowpower
operation in 1.8 V, 2.5 V or 3.3 V systems.
When operating at 2.5 V (or 1.8 V) the part is designed to tolerate
voltages it may encounter on either inputs or outputs when interfacing
to 3.3 V busses. It is guaranteed to be overvoltage tolerant to 3.6 V.
The VCXH16245 is designed with byte control. It can be operated
as two separate octals, or with the controls tied together, as a 16bit
wide function. The Transmit/Receive (T/Rn) inputs determine the
direction of data flow through the bidirectional transceiver. Transmit
(activeHIGH) enables data from A ports to B ports; Receive
(activeLOW) enables data from B to A ports. The Output Enable
inputs (OEn), when HIGH, disable both A and B ports by placing them
in a HIGH Z condition. The data inputs include active bushold
circuitry, eliminating the need for external pullup resistors to hold
unused or floating inputs at a valid logic state.

*NOTE: To ensure the outputs activate in the 3state condition,
the output enable pins should be connected to V
through a
pullup resistor. The value of the resistor is determined by the
current sinking capability of the output connected to the OE pin.
