Texas Instruments CD4010BE

Overview

CD4010BE from Texas Instruments is a hex inverting buffer IC in the CD4000B CMOS logic family, configured as six independent non-inverting buffers with open-drain outputs, operating across -55°C to +125°C, supporting 3V–18V supply range, and used in level-shifting, bus driving, and wired-OR logic applications.

For engineers reviewing the CD4010BE datasheet, CD4010BE pinout, CD4010BE application, or CD4010BE equivalent, this device serves as a high-voltage-tolerant, low-power logic buffer for interfacing between disparate voltage domains, legacy TTL systems, and open-collector bus architectures requiring active-low drive capability.

Technical Context

The CD4010BE implements six identical CMOS inverting buffer stages, each with an open-drain output stage enabling wired-OR configuration and bidirectional level translation. Its input threshold is V_DD/2, ensuring noise-immune switching across the full supply range.

It belongs to the CD4000B series, fabricated using silicon-gate CMOS technology, delivering high noise immunity (≥45% V_DD), ultra-low static current (<100 nA at 18 V), and rail-to-rail output swing when pulled up externally - critical for mixed-voltage system interconnects.

Key Specifications

Pinout & Package

CD4010BE is supplied in a 16-pin plastic dual-in-line package (PDIP-N), 7.62 mm pitch, 19.3 mm length, 6.35 mm width, 3.94 mm height, with pin 1 marked by a notch or dot. The package is RoHS-compliant with NiPdAu lead finish and N/A MSL rating due to hermetic tube packaging.

FAQ

What is the function of CD4010BE?

The CD4010BE is a hex non-inverting buffer with open-drain outputs, meaning it passes input logic states unchanged but can only sink current - requiring external pull-up resistors to define HIGH output levels. It is not an inverter; its truth table is Y = A. This architecture enables wired-OR logic, level shifting, and bus arbitration in CD4010BE-based designs.

Can CD4010BE replace CD4009UB?

No - CD4010BE and CD4009UB are functionally distinct: CD4010BE contains six non-inverting open-drain buffers, while CD4009UB contains six inverting open-drain buffers (Y = NOT A). Swapping them without circuit revision will invert all signals. The pinouts are identical, but logic polarity differs, making CD4010BE unsuitable as a drop-in replacement for CD4009UB unless logic inversion is intentionally removed elsewhere.

What pull-up resistor value should be used with CD4010BE?

A 10 kΩ pull-up resistor is typical for CD4010BE when driving standard TTL loads or 50 pF capacitive loads at ≤1 MHz. For 12 V operation with 6.8 mA sink capability, values from 1.8 kΩ (for fast rise time) to 100 kΩ (for ultra-low power) are valid - actual selection depends on required rise time, bus capacitance, and fan-out. CD4010BE datasheet Figure 6 provides empirical RC timing curves.

Is CD4010BE suitable for 3.3 V operation?

Yes - CD4010BE is fully specified down to 3 V supply, with guaranteed switching thresholds and output drive at that voltage. Input high-level minimum is 2.1 V (70% of 3 V), compatible with 3.3 V CMOS outputs. However, output HIGH level equals the pull-up voltage, not V_DD, so a 3.3 V pull-up yields 3.3 V logic HIGH - confirming CD4010BE interoperability in mixed 3.3 V/5 V systems.

Does CD4010BE have ESD protection?

CD4010BE includes inherent CMOS gate oxide ESD protection rated to ≥2 kV per MIL-STD-883 Method 3015.7 (HBM). No external protection diodes are required for typical board-level handling, though layout best practices - such as short traces, ground-plane proximity, and avoiding floating inputs - remain essential. This ESD rating applies specifically to CD4010BE in PDIP packaging per TI's characterization data.
