74VCXH245
Low−Voltage 1.8/2.5/3.3 V
8−Bit 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 bidirectional 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 pullup resistors to hold unused or floating inputs at a valid
logic state.
Features
Designed for Low Voltage Operation: VCC = 1.65−3.6 V
High Speed Operation: 3.5 ns max for 3.0 to 3.6 V
4.2 ns max for 2.3 to 2.7 V
8.4 ns max for 1.65 to 1.95 V
Static Drive: ±24 mA Drive at 3.0 V
±18 mA Drive at 2.3 V
±6 mA Drive at 1.65 V
Includes Active Bushold to Hold Unused or Floating Data Inputs at a
Valid Logic State
Near Zero Static Supply Current in All Three Logic States (20 mA)
Substantially Reduces System Power Requirements
Latchup Performance Exceeds ±200 mA @ 85°C
ESD Performance:
Human Body Model >2000 V
Machine Model >200 V
