SCES551E – FEBRUARY 2004 – REVISED NOVEMBER 2015
SN74AVC16T245 16-Bit Dual-Supply Bus Transceiver
with Congurable Level-Shifting / Voltage Translation and Tri-State Outputs
1 Features 3 Description
This 16-bit noninverting bus transceiver uses two

• Control Inputs VIH/VIL Levels Are Referenced to separate congurable power-supply rails. The
VCCA Voltage SN74AVC16T245 device is optimized to operate with
• VCC Isolation Feature – If Either VCC Input Is at VCCA/VCCB set at 1.4 V to 3.6 V. The device is
GND, Both Ports Are in the High-Impedance State operational with VCCA/VCCB as low as 1.2 V. The A
port is designed to track VCCA. VCCA accepts any
• Overvoltage-Tolerant Inputs and Outputs Allow
supply voltage from 1.2 V to 3.6 V. The B port is
Mixed-Voltage-Mode Data Communications designed to track VCCB. VCCB accepts any supply
• Fully Congurable Dual-Rail Design Allows Each voltage from 1.2 V to 3.6 V. This allows for universal
Port to Operate Over the Full 1.2 V to 3.6 V low-voltage bidirectional translation between any of
Power-Supply Range the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage
• Io Supports Partial-Power-Down Mode Operation nodes.
• I/Os Are 4.6 V Tolerant The SN74AVC16T245 device is designed for
• Maximum Data Rates asynchronous communication between data buses.
The device transmits data from the A bus to the B
– 380 Mbps (1.8 V to 3.3 V Level-Shifting) bus or from the B bus to the A bus, depending on the
– 200 Mbps (<1.8 V to 3.3 V Level-Shifting) logic level at the direction-control (DIR) input. The
– 200 Mbps (Level-Shifting to 2.5 V or 1.8 V) output-enable (OE) input can be used to disable the
outputs so the buses eectively are isolated.
– 150 Mbps (Level-Shifting to 1.5 V)
– 100 Mbps (Level-Shifting to 1.2 V) The SN74AVC16T245 control pins (1DIR, 2DIR,
1OE, and 2OE) are supplied by VCCA.
