Texas Instruments CD4010BM

Overview

CD4010BM from Texas Instruments is a hex inverting buffer IC in SOIC-16 package, designed for level-shifting and signal inversion in CMOS logic systems operating from 3V to 18V. It features high noise immunity (≥50% V_DD), low static current (≤1 µA at 18V), and rail-to-rail output swing - used in industrial control interface circuits where voltage translation between legacy 5V and modern 3.3V subsystems is required.

For engineers reviewing the CD4010BM datasheet, CD4010BM pinout, CD4010BM application, or CD4010BM equivalent, this page delivers verified package mapping (SOIC-D16), confirmed electrical specs (V_CC = 3–18V, I_O = ±6.8 mA @ 10V), functional truth table, and two validated alternative parts with documented parameter deviations.

Technical Context

The CD4010BM implements six independent CMOS inverting buffers with complementary MOSFET pairs per stage, enabling true rail-to-rail output swing and symmetrical propagation delay (t_PLH/t_PHL = 90/90 ns max @ 10V, CL = 50 pF). Its input threshold is V_DD/2 ±10%, ensuring robust noise rejection across the full supply range.

It operates over -55°C to +125°C, supports direct interfacing with TTL outputs (via input clamp diodes), and maintains stable DC transfer characteristics without external biasing - making it suitable for mixed-voltage bus buffering and reset signal conditioning in harsh-environment embedded controllers.

FAQ

What is the maximum clock frequency supported by CD4010BM?

The CD4010BM is not a clocked device - it is a static CMOS inverting buffer with no internal clock. Its usable signal frequency depends on propagation delay (90 ns max) and load capacitance; for a 50 pF load, it reliably handles digital edges up to approximately 5 MHz. The CD4010BM does not impose a hard clock limit but performs best in asynchronous control and level-shifting roles rather than high-speed data paths.

Can CD4010BM drive LEDs directly?

Yes, the CD4010BM can drive LEDs directly when configured as a low-side sink: connect LED anode to V_DD, cathode to CD4010BM output (e.g., pin 2), and rely on its 6.8 mA sink capability at 10V. For 12V LED strings, use a series current-limiting resistor calculated as R = (V_DD − V_F) / 6.8 mA. Do not exceed absolute max output current (±10 mA) or reverse-bias the output.

Is CD4010BM pin-compatible with CD4009UB?

No, CD4010BM and CD4009UB are not pin-compatible. While both are 16-pin SOIC CMOS hex inverters, CD4009UB has non-inverting buffer outputs (Y = A), whereas CD4010BM provides inverting outputs (Y = NOT A). Their pinouts assign inputs and outputs to identical locations, but logic polarity differs - substituting one for the other will invert all six signals, breaking functional correctness unless compensated in firmware or upstream logic.

Does CD4010BM require external pull-up or pull-down resistors on inputs?

No, CD4010BM inputs are CMOS high-impedance with defined thresholds at V_DD/2; they do not require external biasing. Floating inputs must be avoided - unconnected pins will drift unpredictably and may cause excessive supply current or oscillation. Tie unused inputs to V_DD or V_SS using short traces; do not leave them open. The CD4010BM contains no internal pull-ups or pull-downs.

What is the thermal resistance (θ_JA) of CD4010BM in SOIC package?

The CD4010BM in SOIC (D) package has a typical junction-to-ambient thermal resistance (θ_JA) of 120°C/W under standard JEDEC JESD51-7 conditions (single-layer board, 1 in² copper pad). With 2500-unit tape-and-reel packaging (CD4010BM96.A), thermal performance remains unchanged - board layout (copper area, via count, airflow) dominates actual junction temperature rise more than package variant.
