DESCRIPTION/ORDERING INFORMATION
This 4-bit noninverting bus transceiver uses two separate configurable power-supply rails. 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. The SN74AVCH4T245 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. 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.
