STMicroelectronics HCF4025M013TR

Overview

HCF4025M013TR from STMicroelectronics is a triple 3-input NOR gate IC in CMOS B-series technology, operating from 3V to 20V supply, with typical propagation delay of 50 ns at 10 V/50 pF, buffered inputs/outputs, symmetrical output drive (±1.1 mA at 10 V), and qualified for -55°C to +125°C industrial operation - used in logic-level signal routing and discrete gate-based control circuits.

For engineers reviewing the HCF4025M013TR datasheet, HCF4025M013TR pinout, HCF4025M013TR application, or HCF4025M013TR equivalent, key selection criteria include supply voltage range (3–20 V), input leakage (<100 nA at 18 V), noise margin (2 V min. at 10 V), output drive capability, and DIP-14 package compatibility with legacy through-hole PCB layouts.

Technical Context

The HCF4025M013TR implements three independent 3-input NOR gates using standard CMOS B-series architecture, with fully buffered inputs and outputs to ensure consistent switching thresholds and load driving. Each gate exhibits symmetrical VOH/VOL (9.95 V / 0.05 V at VDD = 10 V) and supports rail-to-rail logic swing across its full 3–20 V operating range.

It complies with JEDEC JESD13B for B-series CMOS devices and specifies quiescent current over temperature (≤150 µA at 20 V, -55°C to +125°C), making it suitable for low-power, wide-temperature industrial control and instrumentation where logic integrity must be maintained under voltage and thermal stress.

FAQ

Is HCF4025M013TR pin-compatible with CD4025BE?

Yes - both are triple 3-input NOR gates in 14-pin DIP packages with identical pin assignments per JEDEC standard. However, HCF4025M013TR offers tighter propagation delay (50 ns vs. 100–200 ns typ. at 10 V), lower input leakage, and guaranteed quiescent current testing across temperature.

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

HCF4025M013TR is characterized up to 50 pF load capacitance with specified propagation delay and transition times. Driving >50 pF may increase tPD and reduce edge rate; for >100 pF loads, add a series resistor or buffer stage to maintain timing integrity and prevent ringing.

Can HCF4025M013TR operate from a 3.3 V supply?

No - while the recommended minimum supply is 3 V, the device is not characterized or guaranteed for 3.3 V operation. At 3.3 V, VOH drops below 2.4 V and noise margin falls below 0.5 V, risking unreliable logic levels. Use only at 5 V or higher for production designs.

Does this part support negative supply voltage on VSS?

No - VSS is defined as ground reference (0 V). The absolute maximum rating allows VSS = -0.5 V relative to system ground, but functional operation requires VSS = 0 V. Applying negative voltage risks latch-up or permanent damage per JEDEC JESD13B guidelines.
