STMicroelectronics HCF4070YM013TR

Overview

HCF4070YM013TR from STMicroelectronics is a quad exclusive OR (XOR) gate IC in SO14 package, operating across 3–20 V supply with 70 ns typical propagation delay at 10 V/50 pF. It delivers rail-to-rail logic output swing, supports automotive-grade temperature range (–40 °C to +125 °C), and is qualified per AEC-Q100 for use in vehicle body control modules requiring deterministic parity checking and data comparison.

For engineers reviewing the HCF4070YM013TR datasheet, HCF4070YM013TR pinout, HCF4070YM013TR application, or HCF4070YM013TR equivalent, key selection criteria include supply voltage flexibility (3–20 V), input leakage ≤100 nA at 18 V, noise margin ≥2 V at 10 V, and automotive-qualified thermal stability.

Technical Context

The HCF4070YM013TR implements four independent CMOS XOR gates using metal-oxide-semiconductor technology. Each gate follows the Boolean function Y = A ⊕ B, with true complementary inputs and outputs referenced to VDD and VSS. The device operates without internal feedback or latching, supporting combinational logic only.

It features symmetric propagation delays (tPLH = tPHL = 70 ns typ. at VDD = 10 V, CL = 50 pF), guaranteed quiescent current testing up to 20 V, and ESD protection rated at 2 kV HBM, 200 V MM, and 1 kV CDM - critical for automotive assembly environments.

FAQ

What is the maximum recommended supply voltage for continuous operation?

The absolute maximum supply voltage is +22 V, but the recommended operating range is 3 V to 20 V. Continuous operation above 20 V risks accelerated parametric drift and reduced long-term reliability, especially at elevated temperatures. ST specifies quiescent current and output drive performance only up to 20 V, and automotive qualification testing was performed within this limit.

Can HCF4070YM013TR drive a 100 pF load reliably?

No - the datasheet characterizes timing and drive strength at CL = 50 pF. At 100 pF, propagation delay increases to ~100 ns (estimated from capacitance scaling trends), and output transition time degrades beyond specification limits. For >50 pF loads, add a buffer stage or reduce trace capacitance via layout optimization.

Is the input hysteresis specified for noise rejection?

No hysteresis is built into the HCF4070YM013TR inputs. Noise margin is achieved solely through CMOS threshold design: VIH = 7 V and VIL = 3 V at VDD = 10 V, yielding 2 V margin. For noisy environments, external RC filtering or Schmitt-trigger buffers are required to prevent metastability.

Does the SO14 package support lead-free reflow soldering?

Yes - the HCF4070YM013TR uses an ECOPACK®-compliant SO14 package qualified for standard lead-free reflow profiles (JEDEC J-STD-020, peak temperature 260 °C). The device meets RoHS Directive 2011/65/EU and has no antimony or halogen restrictions beyond EU thresholds.
