Texas Instruments CD4010BF

Overview

CD4010BF from Texas Instruments is a hex inverting buffer IC in a 16-pin ceramic dual-in-line package (CDIP), designed for level-shifting and signal inversion in legacy CMOS logic systems. It operates across -55°C to +125°C, supports 3–18 V supply range, and delivers rail-to-rail output swing with <1 µA quiescent current - enabling use in battery-backed instrumentation and aerospace subsystems requiring high-reliability discrete logic.

For engineers reviewing the CD4010BF datasheet, CD4010BF pinout, CD4010BF application, or CD4010BF equivalent, this device serves as a non-inverting buffer alternative when paired with external inversion, offers robust noise immunity in mixed-voltage interfacing, and provides verified performance under extended temperature stress without derating.

Technical Context

The CD4010BF implements six independent CMOS inverting buffers using enhancement-mode p- and n-channel MOSFETs in a single monolithic structure. Each stage features symmetrical input thresholds (~50% V_DD) and full rail-to-rail output drive capability, supporting bidirectional voltage translation between logic families operating at different supply rails.

Its design targets compatibility with older CD4000-series systems where low static power, wide supply tolerance, and radiation-tolerant packaging are mandatory. The F3A-suffix ceramic hermetic package ensures hermeticity and thermal stability, distinguishing it from plastic or surface-mount variants in mission-critical analog-digital interface roles.

Key Specifications

Pinout & Package

CD4010BF uses a 16-pin ceramic dual-in-line package (CDIP-J) with 0.3-inch body width, 0.1-inch lead pitch, and hermetic glass-sealed construction. Pin 1 is located at the left end of the top row, identified by a circular index mark adjacent to the lead.

FAQ

What is the maximum supply voltage rating for CD4010BF?

The CD4010BF is rated for continuous operation up to 18 V DC on V_DD, with guaranteed performance across the full -55°C to +125°C temperature range. Exceeding 18 V risks permanent gate oxide damage; transient spikes above 20 V require external clamping. The CD4010BF maintains stable logic thresholds and output drive capability throughout its specified voltage window.

Does CD4010BF support 3.3 V logic levels?

Yes, CD4010BF operates down to 3 V supply and reliably recognizes 3.3 V CMOS inputs as valid HIGH signals, since its input threshold is approximately V_DD/2. At 3.3 V supply, it delivers ~3.1 V HIGH output and ~0.2 V LOW output - sufficient to drive standard 3.3 V CMOS loads. The CD4010BF does not require level translators when interfacing with 3.3 V systems powered from the same rail.

Is CD4010BF pin-compatible with CD4010BE?

Yes, CD4010BF and CD4010BE share identical 16-pin DIP pinouts, electrical specifications, and functional behavior - differing only in package material (ceramic vs. plastic) and lead finish (SNPB vs. NIPDAU). The CD4010BF can directly replace CD4010BE in through-hole sockets, though its hermetic CDIP construction adds weight and cost for non-military applications.

What is the typical propagation delay of CD4010BF at 10 V supply?

At 10 V supply and 25°C, the CD4010BF exhibits a typical propagation delay of 60 ns from input to output, measured between 50% V_DD points under 50 pF capacitive load. This value increases to ~90 ns at -55°C and ~50 ns at +125°C due to carrier mobility shifts. The CD4010BF maintains consistent delay symmetry between rising and falling edges, critical for clock inversion tasks.

Can CD4010BF drive a 10 kΩ pull-up resistor directly?

Yes, CD4010BF can sink or source sufficient current to drive a 10 kΩ pull-up to V_DD while maintaining valid logic levels: at 12 V supply, its VOL remains ≤0.45 V when sinking 1.2 mA, well within TTL and CMOS input thresholds. The CD4010BF's output structure ensures stable DC termination without oscillation or shoot-through, even with resistive loads.
