SN74AVCH16T245
SCES587D â AUGUST 2004 â REVISED NOVEMBER 2015
SN74AVCH16T245 16-Bit Dual-Supply Bus Transceiver
with Configurable Level-Shifting / Voltage Translation and Tri-State Outputs
1 Features
â¢1 VCC Isolation Feature â If Either VCC Input is at
GND, Both Ports are in the High-Impedance State
⢠Control Inputs VIH/VIL Levels Are Referenced to
VCCA Voltage
⢠Overvoltage-Tolerant Inputs and 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
⢠Bus Hold on Data Inputs Eliminates the Need for
External Pullup and Pulldown Resistors
⢠Maximum Data Rates
â 380 Mbps (1.8 V to 3.3 V Level-Shifting)
â 200 Mbps (<1.8 V to 3.3 V Level-Shifting)

3 Description
This 16-bit noninverting bus transceiver uses two
separate configurable power-supply rails. The
SN74AVCH16T245 device is optimized to operate
with VCCA/VCCB set at 1.4 V to 3.6 V. The device 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.
