If your bus fans out to more than one receiver per line, or if you are driving a long backplane trace, the 6 mA limit will force a buffer or a stronger driver. Compare with the 32 mA drive of the SN74LVTH16245ADGVR if your load budget is tighter.","metaTitle":"TI SN74HCT245DBR 74HCT Transceiver, 5.5V 20-SSOP","metaDescription":"Texas Instruments SN74HCT245DBR 8-bit non-inverting transceiver, 3-state outputs, 4.5V–5.5V supply, -40°C to 85°C, 20-SSOP.
