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.
