Texas Instruments CD4010BPWRG4

Overview

CD4010BPWRG4 from Texas Instruments is a hex non-inverting buffer IC in the CD4000B logic family, designed for level-shifting and fan-out expansion in 3–15 V DC supply systems. It features six independent CMOS buffer stages, rail-to-rail output swing, and input thresholds at 50% V_DD, enabling reliable interfacing between TTL, CMOS, and microcontroller I/Os in industrial control and instrumentation circuits.

For engineers reviewing the CD4010BPWRG4 datasheet, CD4010BPWRG4 pinout, CD4010BPWRG4 application, or CD4010BPWRG4 equivalent, key selection criteria include its 16-pin TSSOP package, -55°C to +125°C operating range, 100 nA max quiescent current, and compatibility with legacy CD4000-series timing and interface designs requiring non-inverting buffering without inversion.

Technical Context

The CD4010BPWRG4 implements six identical CMOS non-inverting buffer gates using silicon-gate enhancement-mode P- and N-channel MOSFETs. Each stage provides high noise immunity (V_NIH/V_NIL ≥ 45% V_DD), low static power consumption, and symmetrical propagation delays (typ. 80 ns at 10 V, 50 pF load).

It operates across a wide V_DD range (3 V to 15 V), supports direct connection to TTL outputs (with pull-up if needed), and maintains stable logic levels under capacitive loads up to 50 pF - making it suitable for clock distribution, address/data bus buffering, and signal conditioning in mixed-voltage systems.

FAQ

What is the maximum operating voltage for CD4010BPWRG4?

The CD4010BPWRG4 supports a supply voltage range from 3 V to 15 V DC. Its absolute maximum rating is 20 V, but sustained operation above 15 V is not recommended. At 15 V, output drive capability reaches ±4.2 mA, and propagation delay remains within specification - making CD4010BPWRG4 ideal for industrial systems using unregulated 12 V rails or battery-backed 9–15 V supplies.

Is CD4010BPWRG4 pin-compatible with CD4049UB or CD4050B?

Yes, CD4010BPWRG4 shares the same 16-pin TSSOP (PW) footprint and pin assignment as CD4049UB (hex inverter) and CD4050B (hex non-inverting buffer). While CD4049UB provides inverted outputs, CD4010BPWRG4 and CD4050B are functionally identical - allowing direct PCB substitution where non-inverting logic is required, provided the supply and loading conditions match.

Does CD4010BPWRG4 require external pull-up resistors on inputs?

No, CD4010BPWRG4 does not require external pull-up resistors on inputs. Its CMOS inputs have extremely high impedance (>100 MΩ) and defined thresholds at 50% V_DD. However, floating inputs must be avoided - unused inputs should be tied to V_DD or GND to prevent oscillation and excess current draw. This behavior is intrinsic to CD4010BPWRG4's silicon-gate structure and applies across its full temperature range.

What is the thermal performance of CD4010BPWRG4 in TSSOP-16 package?

The CD4010BPWRG4 in TSSOP-16 (PW) package has a junction-to-ambient thermal resistance (θ_JA) of 160°C/W under standard JEDEC 2-layer board conditions. With its 100 nA max quiescent current, self-heating is negligible - even at 125°C ambient, junction temperature stays within limits. No heatsink or thermal pad is required, though PCB copper pour under the exposed pad improves margin in high-density layouts.

Can CD4010BPWRG4 drive a 50 pF capacitive load reliably?

Yes, CD4010BPWRG4 is fully characterized to drive up to 50 pF capacitive loads while maintaining specified propagation delay (80 ns typ at 10 V) and output voltage swing (V_OH ≥ V_DD – 0.1 V, V_OL ≤ 0.1 V). This makes CD4010BPWRG4 suitable for driving PCB traces, multiple gate inputs, or small display segments without signal degradation - confirmed across -55°C to +125°C per TI's SCHS020C datasheet.
