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.) • CD4049UB Inverting CD4050B Noninverting High Sink Current for Driving 2 TTL Loads High-to-Low Level Logic Conversion 100% Tested for Quiescent Current at 20 V Maximum Input Current of 1 µA at 18 V Over Full Package Temperature Range; 100 nA at 18 V and 25°C 5-V, 10-V, and 15-V Parametric Ratings 2 Applications • • • CMOS to DTL or TTL Hex Converters CMOS Current Sink or Source Drivers CMOS High-to-Low Logic Level Converters Device Information PART NUMBER(1) PACKAGE BODY SIZE (NOM) CD4049UBE, CD4050BE PDIP (16) 6.35 mm × 19.30 mm CD4049UBD, CD4050BD SOIC (16) 9.90 mm × 3.91 mm CD4049UBDW, CD4050BDW SOIC (16) 10.30 mm × 7.50 mm CD4049UBNS, CD4050BNS SO (16) 10.30 mm × 5.30 mm CD4049UBPW, CD4050BPW TSSOP (16) 5.00 mm × 4.40 mm (1) For all available packages, see the orderable addendum at the end of the data sheet.

These devices do logic-level conversions and have a high sink current that can drive two TTL loads. These devices also have low input current of 1 µA across the full temperature range at 18 V. The CD4049UB and CD4050B devices are designated as replacements for CD4009UB and CD4010B devices, respectively. Because the CD4049UB and CD4050B require only one power supply, they are preferred over the CD4009UB and CD4010B and should be used in place of the CD4009UB and CD4010B in all inverter, current driver, or logic-level conversion applications. In these applications the CD4049UB and CD4050B are pin compatible with the CD4009UB and CD4010B respectively, and can be substituted for these devices in existing as well as in new designs. Pin 16 (NC) is not connected internally on the CD4049UB or CD4050B, therefore, connection to this terminal is of no consequence to circuit operation. TI recommends the CD4069UB hex inverter is recommended for applications not requiring high sink-current or voltage conversion. 8.2 Functional Block Diagram CD4050B 3 2 A 5 4 B 7 10 D 11 12 E 14 A H=B B I=C C J=D D K= E E 15 F L= F F 2 G=A 5 6 C 9 3 G= A 4 H=B 7 6 I=C 9 10 J=D 11 12 K=E 14 1 15 L=F 1 VCC VCC 8 8 VSS VSS NC = 13 NC = 16 NC = 13 NC = 16 Copyright © 2016, Texas Instruments Incorporated 8.3 Feature Description CD4049UB and CD4050B have standardized symmetrical output characteristics and a wide operating voltage from 3 V to 18 V with quiescent current tested at 20 V.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information The CD4049UB and CD4050B devices have low input currents of 1 µA at 18 V over full package-temperature range and 100 nA at 18 V, 25°C. These devices have a wide operating voltage from 3 V to 18 V and used in high-voltage applications. 9.2 Typical Application VCC C Logic signal LED R Copyright © 2016, Texas Instruments Incorporated Figure 9-1. CD4049UB Application 9.2.1 Design Requirements The CD4049UB device is the industry's highest logic inverter operating at 18 V under recommended conditions. These devices have high sink current capabilities. 9.2.2 Detailed Design Procedure The recommended input conditions for Figure 9-1 includes rise time and fall time specifications (see Δt/ΔV in Recommended Operating Conditions) and specified high and low levels (see VIH and VIL in Recommended Operating Conditions). Inputs are not overvoltage tolerant and must be below VCC level because of the presence of input clamp diodes to VCC. The recommended output condition for the CD4049UB application includes specific load currents. Load currents must be limited so as to not exceed the total power (continuous current through VCC or GND) for the device. These limits are in the Absolute Maximum Ratings. Outputs must not be pulled above VCC.

Typical Power Dissipation vs Input Rise and Fall Times Per Inverter for CD4049UB and Fall Times Per Buffer for CD4050B 10 Power Supply Recommendations The power supply can be any voltage between the minimum and maximum supply voltage rating in Recommended Operating Conditions. Each VCC pin must have a good bypass capacitor to prevent power disturbance. For devices with a single supply, TI recommends a 0.1-µF capacitor. If there are multiple VCC pins, then TI recommends a 0.01-µF or 0.022-µF capacitor for each power pin. It is acceptable to parallel multiple bypass capacitors to reject different frequencies of noise. 0.1-µF and 1-µF capacitors are commonly used in parallel. The bypass capacitor must be installed as close to the power pin as possible for best results. 11 Layout 11.1 Layout Guidelines When using multiple bit logic devices, inputs must never float. In many cases, digital logic device functions or parts of these functions are unused (for example, when only two inputs of a triple-input and gate are used, or only 3 of the 4 buffer gates are used). Such input pins must not be left unconnected because the undefined voltages at the outside connections result in undefined operational states. This rule must be observed under all circumstances specified in the next paragraph. All unused inputs of digital logic devices must be connected to a high or low bias to prevent them from floating. See Implications of Slow or Floating CMOS Inputs for more information on the effects of floating inputs. The logic level must apply to any particular unused input depending on the function of the device. Generally, they are tied to GND or VCC (whichever is convenient). 11.2 Layout Example VCC Unused Input Input Output Unused Input Output Input Figure 11-1.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 12.7 Glossary TI Glossary This glossary lists and explains terms, acronyms, and definitions. 13 Mechanical, Packaging, and Orderable Information The following pages include mechanical, packaging, and orderable information.
