Apart from the "minor detail" of being inverters and not buffers, the 74HC2G14 / 74HCT2G14 comes much closer to the transition currents that you desire. Available drive current is in the order of 4 mA at Vcc =3D 5V. Ye olde tech HC/HCT seems to still have some advantages (as Bob noted). 2 x 2 input ANDs or 4 x inverters would provide 2 buffers if available. https://assets.nexperia.com/documents/data-sheet/74HC_HCT2G14.pdf Icc peak for Vcc 0.2 / 0.6 mA low-high / high-low at Vcc =3D 5V and 60 / 80 uA at Vcc =3D 2V Russell --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
