74VCXH245
Low鈭扸oltage 1.8/2.5/3.3V
8鈭払it Transceiver
(3-State, Non-Inverting with Bushold)
The 74VCXH245 is an advanced performance, non-inverting 8-bit
transceiver. It is designed for very high-speed, very low-power
operation in 1.8 V, 2.5 V or 3.3 V systems.
The 74VCXH245 is designed as a byte control. The
Transmit/Receive (T/Rn) inputs determine the direction of data flow
through the bi- directional transceiver. Transmit (active- HIGH)
enables data from A ports to B ports; Receive (active-LOW) enables
data from B to A ports. The Output Enable input (OE), when HIGH,
disables 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-up resistors to hold unused or floating inputs at a
valid logic state.
