These hex buffers are monolithic complementary mos (CMOS) integrated circuits constructed with n- and p-channel enhancement mode transistors. These devices feature logic level conversion using only one supply voltage (VDC). the input signal level can exceed the VDC supply voltage when these devices are used for logic level conversions. These devices are intended for use as hex buffers, CMOS to dtl/TTL converters, or as CMOS current drivers, and at vdd=5.0V, they can drive directly two dtl/TTL loads over the full operating temperature range.
