CD4049A, CD4050A Typ s COS/MOS Hex Buffer/Converters
RECOMMENDED OPERATING CONDITIONS at TA=25 0 C, Except as Noted.
For maximum reliability, nominal operating conditions should be selected so that
operation IS always Within the following ranges: CD4049A-lnverting Type
CD4050A-Non-lnverting Type
The CD4049A and CD4050A are inverting
and non-inverting hex buffers, respectively,
and feature logic-level conversion using o.nly
one supply voltage (VCC)-The input-signal
high level (V I H) can exceed the V CC supply
voltage when these devices are used for logiclevel conversions_ These devices are intended
for use as COS/MOS to DTL/TTL converters
and can drive directly two DTL/TTL loads_
(VCC=5 V, VOL ~0.4 V, and IDN ~3.2 mA.)
The CD4049A and CD4050A are designated
as replacements for CD4009A and CD4010A,
respectively. Because the CD4049A and
CD4050A require only one power supply,
they are preferred over the CD4009A and
CD4010A and should be used in place of the
CD4009A and CD4010A in all inverter, current driver, or logic-level conversion applications. In these applications the CD4049A
and CD4050A are pin compatible with the …
