74VCX245
Low Voltage Bidirectional Transceiver
with 3.6V Tolerant Inputs and Outputs
General Description
The VCX245 contains eight non-inverting bidirectional buff-
ers with 3-STATE outputs and is intended for bus oriented
applications. The T/R input determines the direction of data
flow. The OE input disables both the A and B ports by plac-
ing them in a high impedance state.
The 74VCX245 is designed for low voltage (1.4V to 3.6V)
VCC applications with I/O compatibility up to 3.6V.
The 74VCX245 is fabricated with an advanced CMOS
technology to achieve high-speed operation while main-
taining low CMOS power dissipation.
Features
s 1.4V to 3.6V VCC supply operation
s 3.6V tolerant inputs and outputs
s Power-off high impedance inputs and outputs
s Supports Live Insertion and Withdrawal (Note 1)
s tPD
3.5 ns max for 3.0V to 3.6V VCC
s Static Drive (IOH/IOL)
r24 mA @ 3.0V VCC
circuitry
s Latchup performance exceeds 300 mA
s ESD performance:
Human body model
! 2000V
Machine model
! 200V
s Leadless DQFN Pb-Free package
Note 1: To ensure the high impedance state during power up and power
down, OEn should be tied to VCC through a pull up resistor. The minimum
value of the resistor is determined by the current sourcing capability of the
driver.
Ordering Code:
Pb-Free package per JEDEC J-STD-020B.
Note 2: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
