Product details

Overview

HCF4555M013TR from STMicroelectronics is a dual 1-of-4 decoder/demultiplexer in SO-16 package, operating from 3 V to 20 V supply, with output-high-on-select logic, 70 ns typical propagation delay at 15 V, and ±1 µA max input leakage at 18 V. It serves as a digital address decoder in industrial control panels requiring discrete logic-level signal routing.

For engineers reviewing the HCF4555M013TR datasheet, HCF4555M013TR pinout, HCF4555M013TR application, or HCF4555M013TR equivalent, key selection criteria include enable-controlled mutual exclusivity of outputs, symmetrical output drive (±2.4 mA at 15 V), wide-voltage operation up to 20 V, and guaranteed quiescent current testing across temperature.

Technical Context

The HCF4555M013TR implements two independent CMOS binary-to-1-of-4 decoders, each with active-high Enable (E) and two select inputs (A, B). Outputs Q0–Q3 are mutually exclusive and high-true on valid select combinations when E is low.

It complies with JEDEC JESD13B for B-series CMOS devices, features standardized symmetrical output characteristics, and supports expandable decoding architectures-e.g., cascading with HCF4556B to build 1-of-16 decoders-while maintaining noise margins of ≥2.5 V at VDD = 15 V.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	3 V to 20 V - enables direct interface with legacy 5 V, 10 V, and 15 V logic systems without level shifters
Propagation Delay (A/B → Q)	70 ns (typ) at VDD = 15 V - supports reliable timing in sub-10 MHz address decoding applications
Output Drive Current	±2.4 mA at VDD = 15 V - sufficient to directly drive TTL loads or small LED indicators
Input Leakage Current	±1 µA max at VDD = 18 V, TA = 25°C - ensures stable decode state under high-impedance bus conditions
Noise Margin	2.5 V min at VDD = 15 V - provides robust immunity against supply ripple and crosstalk in noisy industrial environments
Operating Temperature	−55°C to +125°C - qualified for under-hood automotive modules and industrial motor drives

Pinout & Package

Package: SO-16 (Small Outline, 16-pin, 3.9 mm body width, 1.27 mm pitch), per mechanical data sheet PO13H.

Pin/Terminal	Circuit Role	Design Meaning
1, 15	E (Enable)	Active-low enable per decoder section; forces all four outputs low when high
2, 3, 13, 14	A, B (Select Inputs)	Binary address inputs selecting one of four outputs per decoder; TTL/CMOS compatible
4–7, 9–12	Q0–Q3 (Outputs)	High-true, mutually exclusive decoded outputs; each sinks or sources up to 2.4 mA
8	VSS	Negative supply reference (GND); must be connected to system ground plane
16	VDD	Positive supply input; decoupling capacitor (100 nF) required within 5 mm

Key Features

Feature	Design Value
Dual independent decoders	Two fully isolated 1-of-4 decode sections share only VDD/VSS rails - eliminates inter-section timing skew
Expandable architecture	Supports hierarchical decoding (e.g., 1-of-8 with single HCF4555B + enable gating, 1-of-16 with HCF4556B)
100% tested quiescent current	Guaranteed I_DD ≤ 600 µA at VDD = 15 V, −55°C to +125°C - critical for battery-backed control logic
Symmetrical output drive	Matched \|I_OH\| and \|I_OL\| (2.4 mA typ at 15 V) - ensures consistent rise/fall times across all outputs

Applications

Industrial PLC I/O Expansion

Automotive Body Control Module

Use Scenario: Routing microcontroller GPIO signals to 16 discrete relay drivers via cascaded decoding.

IC Role / Device Role / Timing Role: Primary address decoder enabling one-of-eight output selection per HCF4555B section, synchronized to MCU clock edges.

Use Value: Eliminates need for external logic gates; 70 ns propagation delay ensures deterministic response within 100 µs scan cycles.

Use Scenario: Selecting among eight lighting zones (headlights, fog lamps, interior LEDs) based on CAN message payload bits.

IC Role / Device Role / Timing Role: Level-shifting and demultiplexing 3-bit CAN-derived address into discrete 12 V lamp control lines.

Use Value: Operates reliably at 12 V nominal (10–16 V range) with 2.4 mA drive - directly interfaces with automotive-rated optocouplers.

Legacy Instrumentation Front Panel

Medical Infusion Pump Display Logic

Use Scenario: Decoding rotary encoder position into discrete segment enable lines for 7-segment LED displays.

IC Role / Device Role / Timing Role: Static address decoder translating 2-bit Gray code into active-high digit selects.

Use Value: Input leakage <1 µA prevents ghosting during encoder idle states; −55°C to +125°C rating suits lab-grade thermal chambers.

Use Scenario: Enabling one of four status indicator LEDs (power, alarm, standby, error) based on microcontroller status register bits.

IC Role / Device Role / Timing Role: Low-power, fail-safe decoder ensuring only one LED illuminates at a time under all fault conditions.

Use Value: Guaranteed mutual exclusivity and 2.5 V noise margin prevent spurious LED activation in EMI-heavy hospital environments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual 1-of-4 decoder applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CD4555BE	Same logic function and pinout; DIP-16 only; wider propagation delay (140 ns max at 15 V)	Lacks SO-16 packaging; unsuitable for surface-mount production	Select when through-hole prototyping or legacy board rework is required
74HC154D	Single 1-of-16 decoder; 24-pin SO; higher speed (23 ns typ), but no enable-per-section architecture	Requires external logic to emulate dual independent decoders; no E-input per section	Select when full 16-line decoding is needed and board space permits larger package

Compared with CD4555BE and 74HC154D, the HCF4555M013TR uniquely delivers dual independent decoders in compact SO-16 with per-section enable control, making it optimal for space-constrained designs requiring modular, cascaded addressing without added glue logic.

FAQ

What is the maximum supply voltage for reliable operation of HCF4555M013TR?

The absolute maximum VDD is +22 V, but recommended operating voltage is 3 V to 20 V. Operation above 20 V risks exceeding the 200 mW total package power dissipation limit and may accelerate long-term parametric drift. At 20 V, quiescent current reaches 3000 µA max, requiring careful thermal design in enclosed enclosures.

Does HCF4555M013TR support true TTL input levels?

Yes - VIH is 11 V min and VIL is 4 V max at VDD = 15 V, providing 3 V noise margin, which exceeds standard TTL thresholds (2 V VIH, 0.8 V VIL). At VDD = 5 V, VIH = 3.5 V and VIL = 1.5 V, ensuring robust interfacing with 74LS and 74ALS families without pull-up resistors.

Can both decoder sections operate simultaneously without interference?

Yes - the two decoder sections are electrically isolated except for shared VDD and VSS pins. Propagation delays, output drive strength, and enable behavior are identical and independent. No internal coupling or timing dependency exists between sections, enabling concurrent decoding of separate address buses.

Is there a lead-free version of HCF4555M013TR available?

Yes - HCF4555M013TR is RoHS-compliant and manufactured with lead-free terminations per STMicroelectronics' current product roadmap. The "TR" suffix denotes tape-and-reel packaging with Pb-free matte tin plating (Sn 100%), qualified to JEDEC J-STD-020 moisture sensitivity level 3.
