3 Description
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 logic-
level 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.)
