74VCXH245
LowVoltage 1.8/2.5/3.3 V
8Bit Transceiver
(3State, NonInverting with Bushold)
The 74VCXH245 is an advanced performance, noninverting 8bit
transceiver. It is designed for very highspeed, very lowpower
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 bidirectional transceiver. Transmit (activeHIGH) enables
data from A ports to B ports; Receive (activeLOW) 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 pullup resistors to hold unused or floating inputs at a valid
logic state.
