SN74AXC1T45/SN74AXC1T45-Q1 Bus Transceivers

Texas Instruments SN74AXC1T45/SN74AXC1T45-Q1 Single-Bit Dual-Supply Bus Transceivers use two single configurable power-supply rails and are operational using both V_CCA and V_CCB supplies. The A port tracks V_CCA, and the B port tracks V_CCB, both accepting supply voltages from 0.65V to 3.6V. The DIR pin determines the direction of signal propagation. When the DIR pin is configured in HIGH mode, translation is from Port A to Port B. Translation is from Port B to Port A when configured in LOW mode. The DIR pin tracks logic-high and logic-low thresholds with V_CCA.
