The SN74LVC1G07 is a high performance  single non−inverting buffer with open drain outputs  operating from a 1.65 to 5.5V supply. The  Output stage is open drain with Over Voltage Tolerance. This allows the SN74LVC1G07 to  be used to interface 5.0V circuits to circuits of any  voltage between 0 and +7.0V

The SN74LVC1G125 is a high performance non−inverting buffer operating from a 1.65V to 5.5V supply. This device is fabricated with advanced CMOS technology to achieve ultra-high speed with high output drive.

The SN74LVC1G17 is a single  Non−inverting Schmitt Trigger Buffer in  three tiny footprint packages.

The CD4049 and CD4050 devices are inverting and noninverting hex buffers, and feature logic-level conversion using only one supply voltage (VCC). The input-signal high level (VIH) can exceed the VCC supply voltage when these devices are used for logiclevel conversions. These devices are intended for use as CMOS to DTL or TTL converters and can drive directly two DTL or TTL loads. (VCC = 5V,VOL ≤ 0.4V, and IOL ≥ 3.3mA.)
