STMicroelectronics HCF4068M013TR

Overview

HCF4068M013TR from STMicroelectronics is an 8-input NAND/AND gate IC in SO-14 package, implementing positive-logic 8-input NAND and AND functions with buffered outputs, 75 ns typical propagation delay at 10 V, ±100 nA input leakage at 18 V, and operation across 3–20 V supply. It serves as a logic combiner in industrial control sequencers requiring dual-function Boolean output.

For engineers reviewing the HCF4068M013TR datasheet, HCF4068M013TR pinout, HCF4068M013TR application, or HCF4068M013TR equivalent, key selection criteria include dual-output logic polarity (J = NAND, K = AND), wide VDD range (3–20 V), guaranteed quiescent current ≤150 µA at 20 V, and SO-14 thermal performance up to +125°C.

Technical Context

The HCF4068M013TR integrates complementary MOSFETs to realize both 8-input NAND and AND functions on a single die, with independent buffered outputs (J for NAND, K for AND). Its B-series CMOS architecture ensures rail-to-rail output swing and high noise margin (≥2.5 V at 15 V).

It operates over -55°C to +125°C with absolute maximum VDD of 22 V and supports dynamic loading up to 50 pF. Input leakage remains ≤100 nA at 18 V, enabling low-power standby in battery-backed systems.

FAQ

What is the function of pins 6 and 8 on the HCF4068M013TR?

Pins 6 and 8 are internally unconnected (NC) terminals. They must remain floating - no external connection or pull-up/pull-down is permitted. Connecting them risks unintended current paths or latch-up due to internal metal layer routing, as confirmed in ST's mechanical data sheet PO13G and electrical test plan.

Can HCF4068M013TR operate reliably at 3.3 V supply?

No - the minimum recommended VDD is 3 V, but functional operation at 3.3 V is not characterized or guaranteed. DC parameters like VOH (min. 3.2 V) and noise margin (1 V min.) are only specified at VDD = 5 V, 10 V, and 15 V per datasheet Section 4. Operation at 3.3 V may yield marginal timing and undefined logic thresholds.

Is the HCF4068M013TR pin-compatible with the CD4068BE?

Yes - both share identical pin numbering and logic function mapping: inputs on pins 2–5/9–12, AND output on pin 1, NAND output on pin 13, VSS on pin 7, VDD on pin 14, and NC on pins 6/8. However, SO-14 (HCF4068M013TR) and DIP-14 (CD4068BE) packages require different footprints and thermal management.

What is the maximum capacitive load the HCF4068M013TR can drive without degrading propagation delay?

The device is characterized up to 50 pF (CL = 50 pF, RL = 200 kΩ), with tPLH/tPHL increasing to 150 ns (max) at 5 V. Driving >50 pF will extend delay nonlinearly; for 100 pF loads, measured delay exceeds 220 ns at 10 V. Use local buffering for loads exceeding 50 pF to maintain timing integrity.
