STMicroelectronics HCF4072M013TR

Overview

HCF4072M013TR from STMicroelectronics is a dual 4-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, output drive capability of ±1.1 mA (VDD = 10 V), and input leakage ≤100 nA at 18 V. It implements positive-logic OR functions for digital control in industrial timing and power sequencing circuits.

For engineers reviewing the HCF4072M013TR datasheet, HCF4072M013TR pinout, HCF4072M013TR application, or HCF4072M013TR equivalent, key selection criteria include supply voltage range (3–20 V), dual independent 4-input OR structure, SO-14 thermal and mounting compatibility, and guaranteed quiescent current testing up to 20 V.

Technical Context

The HCF4072M013TR integrates two independent CMOS OR gates, each accepting four inputs (A–D and E–H) and driving one output (J and K). Its B-series CMOS architecture ensures rail-to-rail output swing, noise margins ≥2 V at VDD = 10 V, and operation from -55°C to +125°C.

It complies with JEDEC JESD13B for B-series CMOS devices and supports direct interface with TTL and other CMOS families via compatible input thresholds (VIH = 7 V, VIL = 3 V at VDD = 10 V) and low-output impedance (IOL = 0.9–2.6 mA).

FAQ

Is HCF4072M013TR pin-compatible with through-hole HCF4072BEY?

Yes - both use identical 14-pin dual-in-line functional pinout (VDD=14, VSS=7, NC=6/8, outputs=1/13, inputs=2–5 and 9–12). The M013TR is the SO-14 surface-mount variant of the BEY DIP part, sharing identical electrical specs and logic function.

Can HCF4072M013TR operate reliably at 18 V supply?

Yes - absolute maximum VDD is +22 V, and all DC parameters (including II ≤100 nA and VOH ≥14.95 V) are specified and tested at 15 V and 20 V. Operation at 18 V falls within recommended 3–20 V range and maintains full parametric compliance.

What is the meaning of "NC" pins 6 and 8?

Pins 6 and 8 are internally not connected - no bond wire or circuit node exists. They must remain unconnected on PCB; routing traces or vias to them risks parasitic capacitance, ESD path disruption, or mechanical stress on leadframe during reflow.

Does HCF4072M013TR support mixed-voltage interfacing (e.g., 3.3 V inputs with 12 V VDD)?

Yes - input voltage range is 0 to VDD, so 3.3 V signals applied to pins 2–5 or 9–12 are fully valid when VDD = 12 V. VIH and VIL thresholds scale with VDD (e.g., VIH = 8.4 V min. at VDD = 12 V), ensuring correct logic interpretation without level shifting.
