Texas Instruments (SN74LVC8T245DBR) Transceiver, 1.65 V to 5.5 V

Product OverviewThe SN74LVC8T245DBR is a 8-bit dual-supply Bus Transceiver with configurablevoltage-level shifting and 3-state outputs. This 8-bit non-inverting bustransceiver uses two separate configurable power-supply rails. It is optimizedto operate with VCCA and VCCB set at 1.65 to 5.5V. The A port is designed totrack VCCA. VCCA accepts any supply voltage from 1.65 to 5.5V. The B port isdesigned to track VCCB. It is designed for asynchronous communication betweentwo data buses. The logic levels of the direction-control (DIR) input and theoutput-enable (OE) input activate either the B-port outputs or the A-portoutputs or place both output ports into the high-impedance mode. The devicetransmits data from the A bus to the B bus when the B-port outputs are activatedand from the B bus to the A bus when the A-port outputs are activated. The inputcircuitry on both A and B ports is always active and must have a logic HIGH orLOW level applied to prevent excess ICC and ICCZ.Control inputs VIH/VIL levels are referenced to VCCA voltageVCC Isolation - If either VCC input is at GND, all are in the high-impedancestateFully configurable dual-rail design allows port to operate over the full 1.65 to5.5V supply rangeLatch-up performance exceeds 100mA per JESD 78, class IIGreen product and no Sb/BrProduct InformationLogic Device Type: Transceiver, Non InvertingLogic Family / Base Number: 74LVC8T245Logic Case Style: SSOPNo. of Pins: 24PinsSupply Voltage Min: 1.65VSupply Voltage Max: 5.5VLogic IC Family: 74LVCLogic IC Base Number: 748T245Operating Temperature Min: -40°COperating Temperature Max: 85°CProduct Range: -Automotive Qualification Standard: -MSL: MSL 1 - Unlimited
