GND, Both Ports Are in the High-Impedance
State
Overvoltage-Tolerant Inputs/Outputs Allow
Mixed-Voltage-Mode Data Communications
Fully Configurable Dual-Rail Design Allows
Each Port to Operate Over the Full 1.2-V to
3.6-V Power-Supply Range
Ioff Supports Partial-Power-Down Mode
Operation
I/Os Are 4.6-V Tolerant
Latch-Up Performance Exceeds 100 mA Per
JESD 78, Class II
ESD Protection Exceeds JESD 22

This 16-bit noninverting bus transceiver uses two
separate
configurable
power-supply
rails.
The
SN74AVC16T245
is
optimized
to
operate
with
VCCA/VCCB set at 1.4 V to 3.6 V. It is operational with
VCCA/VCCB as low as 1.2 V. The A port is designed to
track VCCA. VCCA accepts any supply voltage from
1.2 V to 3.6 V. The B port is designed to track VCCB.
VCCB accepts any supply voltage from 1.2 V to 3.6 V.
This allows for universal low-voltage bidirectional
translation between any of the 1.2-V, 1.5-V, 1.8-V,
2.5-V, and 3.3-V voltage nodes.
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
effectively are isolated.
The SN74AVC16T245 is designed so that the control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied by VCCA.
