74VCXH16245
Low鈭扸oltage 1.8/2.5/3.3V
16鈭払it Transceiver
With 3.6 V鈭扵olerant Inputs and Outputs
(3鈭扴tate, Non鈭捍nverting)
The 74VCXH16245 is an advanced performance, non鈭抜nverting
16鈭抌it transceiver. It is designed for very high鈭抯peed, very low鈭抪ower
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 over鈭抳oltage 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 16鈭抌it
wide function. The Transmit/Receive (T/Rn) inputs determine the
direction of data flow through the bi鈭抎irectional transceiver. Transmit
(active鈭扝IGH) enables data from A ports to B ports; Receive
(active鈭扡OW) 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 pull鈭抲p resistors to hold
unused or floating inputs at a valid logic state.

*NOTE: To ensure the outputs activate in the 3鈭抯tate condition,
the output enable pins should be connected to V

through a
pull鈭抲p resistor. The value of the resistor is determined by the
current sinking capability of the output connected to the OE pin.
