STMicroelectronics HCF4071M013TR

Overview

HCF4071M013TR from STMicroelectronics is a quad 2-input OR gate CMOS logic IC in SO-14 package, operating across 3–20 V supply, with typical propagation delay of 60 ns at 10 V, input leakage ≤100 nA at 18 V, and guaranteed quiescent current testing up to 20 V - used in industrial control logic, power sequencers, and discrete signal combiners.

For engineers reviewing the HCF4071M013TR datasheet, HCF4071M013TR pinout, HCF4071M013TR application, or HCF4071M013TR equivalent, key selection criteria include supply voltage range (3–20 V), output drive capability (±1.1 mA at 10 V), noise margin (2 V min. at VDD = 10 V), and SO-14 thermal performance over –55°C to +125°C.

Technical Context

The HCF4071M013TR implements four independent positive-logic OR gates using standard B-series CMOS process, with rail-to-rail input voltage tolerance (–0.5 V to VDD + 0.5 V) and symmetrical output drive (|IOH| = |IOL| = 1.1 mA typ. at VDD = 10 V). It meets JEDEC JESD13B for B-series CMOS device definition and supports direct interfacing with TTL and other CMOS families.

Its dynamic performance is characterized at CL = 50 pF and RL = 200 kΩ, with tPHL/tPLH asymmetry minimized (50/50 ns typ. at 10 V), and transition times (tTLH/tTHL) tightly controlled (50 ns typ. at 10 V), enabling reliable use in asynchronous combinational logic and enable gating.

FAQ

Is HCF4071M013TR pin-compatible with CD4071BE?

Yes - both share identical 14-pin dual-in-line functional pinout (SO-14 vs. DIP-14), including VDD (pin 14), VSS (pin 7), and OR gate I/O assignments. Mechanical mounting differs, but PCB layout adaptation is straightforward via SO-to-DIP adapter footprints or redesign.

What is the maximum capacitive load this device can drive reliably?

HCF4071M013TR is characterized up to 50 pF load (per JEDEC test condition), with tPHL/tPLH specified at that value. Driving >100 pF may increase propagation delay nonlinearly and reduce noise margin; for heavier loads, add a buffer stage or use lower-VDD operation to improve slew rate.

Does this part support 3.3 V logic systems?

Yes - HCF4071M013TR operates down to 3 V supply and guarantees VIH ≥ 1.5 V and VIL ≤ 1.5 V at VDD = 3 V (extrapolated from 5 V data), making it compatible with 3.3 V CMOS systems when driven by clean, rail-referenced signals.

Is HCF4071M013TR still in active production?

No - STMicroelectronics lists HCF4071M013TR as obsolete per official documentation. However, Aetrix Electronics maintains verified, traceable inventory with full lot-level documentation and offers lifecycle support including cross-reference guidance and long-term supply planning.
