STMicroelectronics HCF4081M013TR

Overview

HCF4081M013TR from STMicroelectronics is a quad 2-input AND gate IC in CMOS technology, operating across 3V–20V supply range with typical propagation delay of 60ns at 10V, quiescent current ≤0.5µA at 10V, and output drive capability of ±1.1mA (IOH/IOL) at VDD=10V. It implements basic logic conjunction in digital control, timing, and interface circuits.

For engineers reviewing the HCF4081M013TR datasheet, HCF4081M013TR pinout, HCF4081M013TR application, or HCF4081M013TR equivalent, key selection criteria include supply voltage flexibility (3–20V), guaranteed noise margin (2V min. at 10V), low input leakage (±0.1µA at 18V), SOP-14 package compatibility, and industrial temperature range (-55°C to +125°C).

Technical Context

The HCF4081M013TR integrates four independent AND gates in a single monolithic CMOS die, each with rail-to-rail input voltage tolerance (0 to VDD) and symmetrical output swing (VOL ≤0.05V, VOH ≥9.95V at VDD=10V). Its propagation delay varies predictably with supply voltage (45ns typ. at 15V, 125ns typ. at 5V) and temperature (0.3%/°C coefficient).

Designed for medium-speed logic interfacing, it supports direct connection between mixed-voltage subsystems-e.g., 5V microcontroller outputs driving 15V analog front-end enable lines-without level shifters, thanks to VIH/VIL thresholds scaling with VDD (e.g., VIH = 7V, VIL = 3V at VDD = 10V).

FAQ

What is the maximum supply voltage for reliable long-term operation?

The absolute maximum VDD is +22V, but the recommended operating limit is 20V per datasheet Section 3. Operation above 20V risks accelerated parametric drift and reduced lifetime, especially at elevated temperatures. For continuous 20V use, derate ambient temperature to ≤85°C and verify quiescent current remains ≤150µA.

Can HCF4081M013TR drive a 100pF load at 1MHz?

No - the datasheet specifies dynamic characteristics only up to 50pF (CL = 50pF). At 100pF, propagation delay increases by ~30% and transition times degrade beyond specification limits. For >50pF loads, add a buffer stage or reduce clock frequency below 500kHz to maintain timing integrity.

Is the SO-14 package RoHS-compliant and lead-free?

Yes - HCF4081M013TR uses a lead-free SO-14 package compliant with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL3). The device carries the "E3" marking on the top surface and ships with dry-pack desiccant per standard tape-and-reel packaging.

How does input leakage current behave at -40°C?

At -40°C, input leakage drops significantly: II is typically ≤±0.01µA (10nA) at VDD = 18V, per characterization data in ST's HCF4000B family reliability report. This improves noise immunity in cold environments but does not affect functional logic thresholds, which remain stable across temperature.
