CD4049A/CD4050A Types CMOS Hex Buffer/Converters
■The CD4049A and CD4050A are inverting and non-inverting hex buffers, respectively, and feature logic-level conversion using only one supply voltage (V-CC). The input-signal high level (V-IH) can exceed the V-CC 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. (V-CC=5 V, V-OL ≥0.4 V, and l-DN ≥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 CD4009A and CD4010A respectively, and can be substituted for these devices in existing as well as in new designs. Terminal No.16 is not connected internally on the CD4049A or CD4050A, therefore, connection to this terminal is of no consequence to circuit operation. For applications not requiring high sink-current or voltage conversion, the CD4069 Hex Inverter is recommended.
■These types are supplied in 16-lead hermetic dual-in-line ceramic packages (D and F suffixes), 1 6-lead dual-in-line plastic pack- age (E suffix), 16-lead ceramic flat packages (K suffix), and in chip form (H suffix).
●Features:
■High sink current for driving 2 TT L loads
■High-to-low level logic conversion
■Quiescent current specified to 15 V
■Maximum input leakage of 1 μA at 15 V (full package-temperature range)
