Texas Instruments CD4071BPWE4

Overview

CD4071BPWE4 from Texas Instruments is a CMOS quad 2-input OR gate designed for general-purpose digital logic, positive-true signal combining, control-line aggregation, status logic, enable generation, timing networks, and embedded board-level logic applications. The device integrates four independent 2-input OR gates in a 14-pin TSSOP package and operates across the wide-voltage CD4000-series CMOS logic range.

As part of the Texas Instruments CD4071B CMOS logic family, CD4071BPWE4 combines wide-voltage operation, buffered outputs, low static power dissipation, high noise immunity, standardized OR-gate logic behavior, and compact surface-mount packaging. For engineers reviewing the CD4071BPWE4 datasheet, CD4071BPWE4 pinout, CD4071BPWE4 application, or CD4071BPWE4 equivalent, this device is widely used in glue logic, status aggregation, interrupt or alarm combining, enable control, signal selection, industrial logic boards, consumer electronics, and general-purpose CMOS digital systems.

Technical Context

In digital logic systems, CD4071BPWE4 provides four independent OR gates. Each gate output goes HIGH when either corresponding input is HIGH; the output remains LOW only when both inputs are LOW. This function is useful for combining positive-true control signals, generating shared status lines, merging enable conditions, and implementing simple combinational logic.

The CD4071B family belongs to the CD4000 CMOS logic series, which is often selected when a broader supply-voltage range is required than standard 74HC logic. This makes CD4071BPWE4 useful in systems where logic rails may operate at 5V, 10V, 12V, or 15V, provided that all input and output levels remain within the datasheet operating limits.

Compared with 74HC32-type OR gates, CD4071BPWE4 is typically chosen for broad-voltage CMOS compatibility rather than high-speed low-voltage logic operation. Designers should compare supply voltage, propagation delay, output drive, input thresholds, package footprint, and timing requirements before substituting CD4071B-family devices into existing logic circuits.

Key Specifications

Pinout & Package

The CD4071BPWE4 pinout uses a 14-pin TSSOP package with four independent OR gate sections. Each section has two logic inputs and one output, with VSS as the ground reference and VDD as the positive supply pin. The package supports compact surface-mount layouts where several OR-gate functions must be implemented in limited PCB area.

For PCB implementation, VDD should be bypassed close to the package, unused inputs should be tied to a valid logic HIGH or LOW level, and output loading should remain within the recommended operating limits. Since CD4000 CMOS devices can be used across a wide voltage range, every connected logic input and output should be checked for voltage-level compatibility with the selected VDD rail.

Applications

Equivalent & Alternatives

When evaluating CD4071BPWE4 equivalent devices, engineers should compare logic family, supply-voltage range, input threshold behavior, propagation delay, output drive, package footprint, temperature range, power consumption, and pin-to-pin compatibility.

Compared with CD4071BM, CD4071BPWE4 is optimized for compact TSSOP / PW package layouts while maintaining the same CD4071B quad OR-gate function. CD4071BPWE4 vs 74HC32PW selection depends mainly on supply-voltage range, logic-family compatibility, propagation delay, output drive, package footprint, and existing board qualification.

Quality

CD4071BPWE4 should be sourced as original Texas Instruments components through traceable and controlled supply channels. Quality verification procedures may include package inspection, top-mark validation, solderability testing, pin continuity checks, input threshold verification, functional OR truth-table testing, supply-current review, output-level measurement, and incoming inspection according to standard logic production requirements.

Because the device is often used in status, enable, timing, and control logic, system reliability depends on valid CMOS input levels, clean supply decoupling, tied unused inputs, correct output loading, stable input timing, and verification that the chosen supply voltage is compatible with all connected logic devices. Traceable sourcing supports manufacturing quality and reduces counterfeit supply-chain risk for CD4000 logic production programs.
