description/ordering information
This 20-bit noninverting bus transceiver uses two
separate configurable power-supply rails.
The SN74AVC20T245 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.
