Product details
Overview
CD4050BQPWRG4TY from Texas Instruments is a noninverting hex buffer IC designed for CMOS-to-TTL/DTL logic-level conversion and high-current sinking in single-supply systems. It operates from 3V to 18V, delivers ≥24mA sink current at VCC = 15V and TA = 25°C, exhibits ≤0.05V VOL at 5V supply, and supports –55°C to +125°C industrial temperature range - used in voltage translation interfaces for microcontroller I/O expansion.
For engineers reviewing the CD4050BQPWRG4TY datasheet, CD4050BQPWRG4TY pinout, CD4050BQPWRG4TY application, or CD4050BQPWRG4TY equivalent, key selection criteria include verified noninverting logic behavior, input voltage tolerance exceeding VCC (VIH up to 12.5V at 15V supply), low 100nA input leakage at 25°C, and TSSOP-16 package compatibility with high-density PCB layouts.
Technical Context
The CD4050BQPWRG4TY implements six independent noninverting buffer stages in a single monolithic CMOS die, each with symmetrical output drive capability and rail-to-rail voltage transfer characteristics. Its input structure allows VIH > VCC (e.g., 12.5V input with 15V VCC), enabling direct high-voltage signal interfacing without external level-shifting components.
It features standardized DC parameters across temperature: VOH ≥ 14.95V at VCC = 15V, VOL ≤ 0.05V at VCC = 5V/10V/15V, and IIN ≤ ±0.1µA at TA = –55°C to 25°C with VCC = 18V - ensuring stable operation in mixed-voltage industrial control and legacy system upgrades.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 3V to 18V - supports direct interface between 3.3V/5V logic and 12V/15V industrial buses without external regulators. |
| IOL (Min) | 24mA at VCC = 15V, TA = 25°C - drives two standard TTL loads (each ~1.6mA) with margin for aging and temperature drift. |
| VOL (Max) | 0.05V at VCC = 5V/10V/15V - ensures robust low-state noise immunity when interfacing with 5V TTL receivers. |
| VIH (Min) | 11V at VCC = 15V, TA = 25°C - enables reliable recognition of 12V logic-high signals in mixed-supply systems. |
| tPHL / tPLH | 15–30ns at VCC = 15V - supports >10MHz digital signal routing in timing-critical sensor interface paths. |
| IIN (Max) | ±0.1µA at VCC = 18V, TA = –55°C to 25°C - minimizes loading on high-impedance analog or battery-powered sensor outputs. |
| Operating Temp | –55°C to +125°C - qualified for under-hood automotive, motor drive, and outdoor industrial environments. |
Pinout & Package
Packaged in a 16-pin TSSOP (PW) measuring 5.00mm × 4.40mm with 0.65mm pitch, the CD4050BQPWRG4TY uses surface-mount construction optimized for automated assembly and thermal performance (RθJA = 108.4°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, VCC | Positive supply | Single power rail input; must be bypassed with 0.1µF ceramic capacitor placed within 2mm of pin. |
| 2, G | Output 1 | Noninverting buffered replica of Input A; capable of sourcing/sinking ≥24mA at 15V. |
| 3, A | Input 1 | CMOS input tolerant up to 12.5V when VCC = 15V; requires external pull-up/down if unused. |
| 4, H | Output 2 | Noninverting buffered replica of Input B; electrically isolated from other channels. |
| 5, B | Input 2 | Independent logic input; no internal connection to other inputs or outputs. |
| 6, I | Output 3 | Noninverting buffered replica of Input C; shares same VCC/VSS rails but no crosstalk coupling. |
| 7, C | Input 3 | High-impedance CMOS node; leakage ≤100nA at 25°C ensures minimal power loss in battery systems. |
| 8, VSS | Negative supply / GND | Reference return path for all six buffers; must connect to low-impedance ground plane. |
| 9, D | Input 4 | Unused inputs must be tied to VCC or VSS - floating states cause undefined output and increased ICC. |
| 10, J | Output 4 | Noninverting buffered replica of Input D; matches propagation delay (tPHL/tPLH) of other channels. |
| 11, E | Input 5 | Input threshold defined by VCC ratio; VIH = 11V min at VCC = 15V ensures clean switching at 12V logic levels. |
| 12, K | Output 5 | Noninverting buffered replica of Input E; VOL ≤ 0.05V guarantees TTL-compatible low state. |
| 13, NC | No connection | Internally unconnected; may be left unpopulated or grounded - no electrical effect on operation. |
| 14, F | Input 6 | Last input channel; identical electrical specs to A–E; supports full hex-buffer utilization. |
| 15, L | Output 6 | Noninverting buffered replica of Input F; completes six-channel bidirectional interface capability. |
| 16, NC | No connection | Internally unconnected; no routing or soldering required; does not affect thermal or electrical performance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar noninverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4050BE | PDIP-16 package; RθJA = 49.5°C/W; no moisture sensitivity level rating; leaded finish. | Through-hole assembly only; unsuitable for automated SMT lines or high-reliability sealed enclosures. | Select CD4050BE only for prototyping, repair, or legacy through-hole designs where reflow compatibility is irrelevant. |
| SN74HC244N | CMOS octal buffer; 2V–6V VCC range; 3.5mA IOL max; 50pF CIN; 25ns tPD typical at 5V. | Limited to 5V systems; cannot translate 12V/15V inputs; lower drive strength insufficient for dual-TTL loads. | Choose SN74HC244N only for cost-sensitive 5V-only applications where high-voltage tolerance and 24mA drive are unnecessary. |
Compared with CD4050BE and SN74HC244N, the CD4050BQPWRG4TY uniquely combines 15V input tolerance, 24mA sink capability, and TSSOP-16 packaging - making it the only option for space-constrained, mixed-voltage industrial control where both voltage translation and load driving are required.

FAQ
What is the maximum input voltage the CD4050BQPWRG4TY can accept when VCC = 15V?
The CD4050BQPWRG4TY specifies VIH(Min) = 11V at VCC = 15V and TA = 25°C, meaning it reliably recognizes logic-high inputs ≥11V. Absolute maximum ratings allow input voltages up to 20V, but sustained operation above VCC risks latch-up or accelerated degradation. For continuous 12V signal interfacing, the CD4050BQPWRG4TY is fully rated and widely deployed in industrial controls.
Does the CD4050BQPWRG4TY support true bidirectional signal translation?
No, the CD4050BQPWRG4TY is a unidirectional noninverting buffer: signals flow strictly from pins A–F (inputs) to G–L (outputs). It does not support automatic direction sensing or bus arbitration. For bidirectional translation (e.g., I²C), separate dedicated level shifters like TXS0108E are required. The CD4050BQPWRG4TY is intended for fixed-direction voltage translation only.
Can unused inputs on the CD4050BQPWRG4TY be left floating?
No, unused inputs on the CD4050BQPWRG4TY must be tied to either VCC or VSS. Floating CMOS inputs cause undefined output states, increased quiescent current (IDD), and potential oscillation due to noise coupling. TI explicitly recommends connecting all unused inputs to a defined rail - this applies equally to CD4050BQPWRG4TY and all members of the CD4000B logic family.
What is the thermal resistance (RθJA) of the CD4050BQPWRG4TY in its TSSOP-16 package?
The CD4050BQPWRG4TY in PW (TSSOP-16) package has a junction-to-ambient thermal resistance (RθJA) of 108.4°C/W, as specified in TI's SCHS046L datasheet Section 5.4. This value assumes standard JEDEC 2-layer board conditions. For higher-power applications, thermal relief pads and copper pours under the exposed pad (if present) or adjacent VCC/VSS traces significantly improve heat dissipation.
Is the CD4050BQPWRG4TY pin-compatible with older CD4050B variants?
Yes, the CD4050BQPWRG4TY is functionally and pinout-compatible with all CD4050B variants including CD4050BE (PDIP), CD4050BD (SOIC), and CD4050BDW (SOIC wide). All share identical pin numbering, logic function, and electrical specifications. The "QPWRG4TY" suffix denotes TI's green, RoHS-compliant, TSSOP-16 packaging with NiPdAu lead finish and Level-1 MSL rating - no circuit redesign is needed for migration.
