74ALVC162245
Low Voltage 16-Bit Bidirectional Transceiver
with 3.6V Tolerant Inputs and Outputs
and 26
Ω Series Resistors in A Port Outputs
General Description
The ALVC162245 contains sixteen non-inverting bidirec-
tional buffers with 3-STATE outputs and is intended for bus
oriented applications. The device is byte controlled. Each
byte has separate 3-STATE control inputs which can be
shorted together for full 16-bit operation. The T/R inputs
determine the direction of data flow through the device.
The OE inputs disable both the A and B Ports by placing
them in a high impedance state.
The 74ALVC162245 is designed for low voltage (1.65V to
3.6V) VCC applications with I/O compatibility up to 3.6V.
The 74ALVC162245 is also designed with 26
Ω series
resistance in the A Port outputs. This design reduces line
noise in applications such as memory address drivers,
clock drivers, and bus transceivers/transmitters.
The 74ALVC162245 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
Features
I 1.65V–3.6V VCC supply operation
I 3.6V tolerant inputs and outputs
I 26
Ω series resistors in A Port outputs
I tPD
3.9 ns max for 3.0V to 3.6V VCC
4.8 ns max for 2.3V to 2.7V VCC
8.6 ns max for 1.65V to 1.95V VCC
I Power-down high impedance inputs and outputs
I Supports live insertion/withdrawal (Note 1)
I Uses patented noise/EMI reduction circuitry
I Latchup conforms to JEDEC JED78
I ESD performance:
Human body model
> 2000V
Machine model
>200V
Note 1: To ensure the high-impedance state during power up or power
down, OE 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:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
