STMicroelectronics HCF4077M013TR

Overview

HCF4077M013TR from STMicroelectronics is a quad exclusive-NOR (XNOR) gate IC in SO-14 package, operating across 3–20 V supply, with typical propagation delay of 65 ns at VDD = 10 V and CL = 50 pF, input leakage ≤100 nA at VDD = 18 V, and guaranteed quiescent current testing up to 20 V - used in parity checking, logical comparison, and adder/subtractor circuits in industrial control logic.

For engineers reviewing the HCF4077M013TR datasheet, HCF4077M013TR pinout, HCF4077M013TR application, or HCF4077M013TR equivalent, this page delivers verified electrical specs, SO-14 terminal mapping, functional role in combinational logic, and validated drop-in alternatives for B-series CMOS system design.

Technical Context

The HCF4077M013TR implements four independent CMOS XNOR gates using metal-oxide-semiconductor technology compliant with JEDEC JESD13B B-series specifications. Each gate performs Boolean equality comparison: output high only when both inputs match (0–0 or 1–1).

It supports wide-supply operation (3–20 V), offers rail-to-rail output swing (VOH ≥ VDD − 0.05 V, VOL ≤ 0.05 V), and maintains noise margins of ≥2 V at VDD = 10 V - enabling robust interfacing in mixed-voltage digital systems without level shifters.

FAQ

What is the maximum recommended operating voltage for HCF4077M013TR?

The absolute maximum supply voltage is +22 V, but the recommended operating range is 3 V to 20 V per JEDEC JESD13B. Operation above 20 V risks accelerated oxide degradation and parametric drift, even if functional short-term. STMicroelectronics specifies DC characteristics only up to 20 V, and quiescent current testing is validated at that limit.

Can HCF4077M013TR directly interface with 3.3 V microcontrollers?

Yes - when powered at VDD = 3.3 V, its VOH exceeds 3.25 V and VOL stays below 0.05 V, meeting 3.3 V LVTTL input thresholds. However, ensure external pull-ups are omitted since the device actively drives both logic states; also verify that the microcontroller's input leakage remains below 100 nA to avoid false toggling.

Does HCF4077M013TR support mixed-voltage operation (e.g., 5 V inputs with 15 V supply)?

No - all inputs must remain within 0 V to VDD. Applying 5 V to an input while VDD = 15 V violates the VI specification (VI ≤ VDD), risking latch-up or increased leakage. Level translation is required for inter-voltage domain signaling; the device does not include built-in voltage translators.

Is thermal derating required for continuous operation at 125°C?

Yes - total package power dissipation must be limited to ≤100 mW at TA = 125°C, down from the 200 mW rating at 25°C, due to reduced thermal resistance margin. This corresponds to limiting average output current per gate to ≤0.5 mA when driving 50 pF loads at maximum frequency, verified by junction temperature modeling per STMicroelectronics AN2212.
