description/ordering information
This 20-bit noninverting bus transceiver uses two separate configurable power-supply rails. The
SN74AVCH20T245 is optimized to operate with V
CCA
/V
CCB
set at 1.4 V to 3.6 V. It is operational with V
CCA
/V
CCB
as low as 1.2 V. The A port is designed to track V
CCA
. V
CCA
accepts any supply voltage from 1.2 V to 3.6 V. The
B port is designed to track V
CCB
. V
CCB
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.
