The CD4049BE devices are inverting 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 logic-level conversions. These devices are intended for use as CMOS to DTL/TTL converters and can drive directly two DTL/TTL loads. The CD4049UB and CD4050B 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 = 5 V, VOL ≤ 0.4 V, and IOL ≥ 3.3 mA.)
