POST OFFICE BOX 655303
DALLAS, TEXAS 75265
D Control Inputs VIH/VIL Levels are
Referenced to VCCA Voltage
D VCC Isolation Feature If Either VCC Input
Is at GND, Both Ports Are in the
High-Impedance State
D Overvoltage-Tolerant Inputs/Outputs Allow
Mixed-Voltage-Mode Data Communications
D Fully Configurable Dual-Rail Design Allows
Each Port to Operate Over the Full 1.65-V to
5.5-V Power-Supply Range
D Ioff Supports Partial-Power-Down Mode
Operation
description/ordering information
This 16-bit noninverting bus transceiver uses two
separate configurable power-supply rails. The
A port is designed to track VCCA. VCCA accepts
any supply voltage from 1.65 V to 5.5 V. The B port
is designed to track VCCB. VCCB accepts any
supply voltage from 1.65 V to 5.5 V. This allows for
universal low-voltage bidirectional translation
between any of the 1.8-V, 2.5-V, 3.3-V, and 5-V
voltage nodes.
The
SN74LVC16T245
is
designed
for
asynchronous communication between data
buses. The device transmits data from the A bus
to the B bus or from the B bus to the A bus,
depending
on
the
logic
level
at
the
direction-control (DIR) input. The output-enable
(OE) input can be used to disable the outputs so
the buses are effectively isolated.
The SN74LVC16T245 is designed so that the
control pins (1DIR, 2DIR, 1OE, and 2OE) are
supplied by VCCA.
