STMicroelectronics HCF4014M013TR

Overview

HCF4014M013TR from STMicroelectronics is an 8-stage synchronous static shift register with parallel/serial input and serial output, implemented as D-type master-slave flip-flops plus output buffering. It operates up to 12 MHz (typ.) at VDD = 10 V, supports 3–20 V supply range, features ±100 nA max input leakage at 18 V, and provides Q6, Q7, and Q8 buffered outputs for cascaded timing control in industrial logic systems.

For engineers reviewing the HCF4014M013TR datasheet, HCF4014M013TR pinout, HCF4014M013TR application, or HCF4014M013TR equivalent, key selection criteria include static operation capability, parallel jam functionality, clock-synchronous data entry, wide VDD tolerance (3–20 V), and verified 125 °C operational temperature rating.

Technical Context

The HCF4014M013TR implements a fully static 8-bit shift register with dual-mode control: when PARALLEL/SERIAL CONTROL is high, all eight PI inputs load synchronously on the rising clock edge; when low, serial data shifts in via SERIAL IN on each rising clock edge. Internal D-type master-slave stages ensure glitch-free state retention during hold periods.

It delivers three buffered serial outputs (Q6, Q7, Q8) with VOH ≥ 9.95 V and VOL ≤ 0.05 V at VDD = 10 V, supports propagation delays as low as 60 ns (typ.) at 15 V, and maintains noise margins of ≥2 V at 10 V supply-enabling robust interfacing in mixed-voltage digital systems.

FAQ

Is HCF4014M013TR pin-compatible with CD4014BE?

Yes, HCF4014M013TR uses the same SO-16 pinout and logic function as CD4014BE, including identical PI1–PI8, SERIAL IN, PARALLEL/SERIAL CONTROL, CLOCK, Q6–Q8, VDD, and VSS assignments. Electrical differences exist in timing and temperature rating, but PCB layout and firmware remain unchanged.

What is the minimum clock pulse width required for reliable operation?

At VDD = 10 V, the minimum clock pulse width is 40 ns (high) and 40 ns (low), per datasheet Table 5. This ensures full master-slave latch capture and avoids metastability. For margin-critical designs, maintain ≥60 ns pulse width and ≤20 ns rise/fall times.

Can HCF4014M013TR operate with a 3.3 V supply?

No. The recommended minimum VDD is 3 V, but the device is not characterized or guaranteed for 3.3 V operation. Input thresholds scale with VDD, and at 3.3 V, VIH would be ~2.3 V and VIL ~1.1 V-outside standard 3.3 V logic margins. Use only within specified 5 V, 10 V, or 15 V parametric ratings.

Does it support asynchronous reset or clear functionality?

No. The HCF4014M013TR has no dedicated reset or clear input. State initialization relies solely on parallel jam (with PI1–PI8) or serial shifting of known values. External reset circuitry or microcontroller-controlled parallel load is required for deterministic startup conditions.
