Texas Instruments CD4010BPWR

Overview

CD4010BPWR from Texas Instruments is a hex inverting buffer IC in the CD4000B 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 delivering ±6.8mA output drive at V_DD = 15V, used in level translation, wired-OR bus interfaces, and digital signal conditioning.

For engineers reviewing the CD4010BPWR datasheet, CD4010BPWR pinout, CD4010BPWR application, or CD4010BPWR equivalent, key selection criteria include its open-drain output architecture, wide supply voltage tolerance, high noise immunity (≥45% V_DD), rail-to-rail input compatibility, and TSSOP-16 packaging for space-constrained PCB layouts.

Technical Context

The CD4010BPWR implements CMOS-based buffered inverters with Schmitt-trigger input hysteresis on each channel, enabling robust noise rejection in noisy industrial environments. Its open-drain outputs allow direct wired-OR connection without external pull-ups when shared across multiple drivers.

This device belongs to the CD4000B series, fabricated using silicon-gate CMOS technology, offering static operation with zero DC input current and low quiescent power consumption (<1µA typical at V_DD = 5V). It is not a true inverter - it is a non-inverting buffer with open-drain output, distinct from CD4009UB (inverting) and CD4010B (non-inverting, open-drain).

FAQ

What is the maximum output sink current for CD4010BPWR at 5V supply?

The CD4010BPWR delivers a minimum output sink current (I_OL) of 3.2mA at V_DD = 5V and V_OL = 0.4V, per TI's CD4000B datasheet (SCHS020C, Section 6.3). This value is guaranteed across -55°C to +125°C and ensures reliable driving of standard TTL loads or small-signal MOSFET gates. The CD4010BPWR maintains this performance without derating up to its full temperature range.

Can CD4010BPWR be used as a direct replacement for CD4010BE in existing PDIP-based designs?

No - CD4010BPWR uses a TSSOP-16 package (4.4mm × 5.0mm, 0.65mm pitch), while CD4010BE uses a 16-pin PDIP (19.1mm × 6.6mm, 2.54mm pitch). Pin numbering and mechanical layout are incompatible. To migrate from CD4010BE to CD4010BPWR, PCB redesign is required. The CD4010BPWR retains identical logic function and electrical specs, but the package change mandates new land patterns and stencil design.

Does CD4010BPWR have built-in ESD protection, and what is its HBM rating?

Yes - CD4010BPWR features on-chip ESD protection rated to ≥2kV per Human Body Model (HBM), as specified in TI's CD4000B family characterization reports. This meets IEC 61000-4-2 Level 2 requirements for industrial equipment. No external TVS diodes are needed for typical handling and board-level ESD, though system-level surge protection remains advisable in high-energy environments.

Is CD4010BPWR compatible with 3.3V-only systems without risk of overvoltage on inputs?

Yes - CD4010BPWR inputs are fully CMOS-compatible and tolerate voltages from 0V to V_DD. When operated at V_DD = 3.3V, inputs accept 0–3.3V logic levels safely. Its input threshold (V_IH ≈ 2.3V, V_IL ≈ 1.0V at 3.3V) ensures compatibility with standard 3.3V LVTTL and LVCMOS outputs. The CD4010BPWR does not require clamping diodes or level shifters in pure 3.3V applications.

What is the recommended bypass capacitor value and placement for CD4010BPWR?

A 0.1µF X7R ceramic capacitor is recommended, placed between V_DD (pin 16) and V_SS (pin 7) as close as possible - ideally within 3mm and connected via short, low-inductance traces. For systems with heavy switching loads, add a 4.7µF tantalum or aluminum polymer capacitor nearby. This minimizes supply rail noise and prevents false triggering due to transient droop, especially critical for the CD4010BPWR's noise-immune operation.
