STMicroelectronics HCF4015M013TR

Overview

HCF4015M013TR from STMicroelectronics is a dual 4-stage static shift register IC with serial input/parallel output architecture, implemented using B-series CMOS technology. It contains two independent D-type master-slave flip-flop registers, each with dedicated CLOCK, RESET, and DATA inputs, plus four buffered Q outputs per register. Operates up to 12 MHz (typ.) at VDD = 10 V, supports 3–20 V supply, and delivers high noise immunity with VIH/VIL margins of 7 V / 3 V at 10 V.

For engineers reviewing the HCF4015M013TR datasheet, HCF4015M013TR pinout, HCF4015M013TR application, or HCF4015M013TR equivalent, key selection considerations include dual-register independence, static operation capability, 16-pin SOIC package compatibility, clocked serial-to-parallel data conversion, and JEDEC JESD13B compliance for B-series CMOS devices.

Technical Context

The HCF4015M013TR implements two fully static, edge-triggered D-type master-slave flip-flop chains, each accepting serial data on positive clock transitions and enabling parallel readout from all four stages. Reset is asynchronous and active-high, clearing all flip-flops simultaneously per register.

It features rail-to-rail input voltage tolerance (–0.5 V to VDD + 0.5 V), guaranteed quiescent current testing up to 20 V, and dynamic timing characterized at CL = 50 pF with RL = 200 kΩ. Propagation delays scale inversely with VDD: tPLH/tPHL = 80/160 ns (typ./max) at 10 V, and fCL reaches 12 MHz (typ.) under those conditions.

FAQ

Is HCF4015M013TR pin-compatible with CD4015BE?

Yes - HCF4015M013TR uses the same SO-16 pinout as CD4015BE, including identical CLOCK A/B, RESET A/B, DATA A/B, and Q-output assignments. Both share identical functional diagrams and truth tables per STMicroelectronics and Texas Instruments documentation.

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

HCF4015M013TR is characterized with CL = 50 pF and RL = 200 kΩ. Its output drive strength (±1.1 mA at VDD = 10 V) supports up to ~75 pF total load capacitance while maintaining specified propagation delay and transition time, assuming proper PCB layout and decoupling.

Can HCF4015M013TR operate at 3.3 V supply?

Yes - the recommended operating range starts at 3 V. At 3.3 V, VOH is ≥3.2 V and VOL ≤0.1 V (per DC specs), and fCL drops to ~3 MHz (typ.), making it usable in mixed-voltage systems with appropriate timing margin analysis.

Does this part support cascading beyond 8 bits?

Yes - the dual-register architecture allows direct cascading: connect Q4A to DATA B and use shared CLOCK/RESET to form an 8-bit shift register. Additional HCF4015B units can extend further, with propagation delay accumulating linearly per stage.
