Product details

Overview

HCF4512M013TR from STMicroelectronics is an 8-channel CMOS data selector with three-state output, designed for bus-oriented digital systems requiring multiplexed data routing and high-impedance isolation. It operates from 3 V to 20 V, delivers ±3.2 mA output drive at VDD = 5 V, supports −55 °C to +125 °C operation, and features input leakage ≤100 nA at 18 V - used in industrial control backplanes and legacy instrumentation interfaces.

For engineers reviewing the HCF4512M013TR datasheet, HCF4512M013TR pinout, HCF4512M013TR application, or HCF4512M013TR equivalent, key selection criteria include its 3-state enable timing (tPZH/tPLZ ≤40 ns @15 V), symmetrical VOH/VOL (≤0.05 V low, ≥14.95 V high @15 V), and JEDEC JESD13B compliance for B-series CMOS interoperability.

Technical Context

The HCF4512M013TR implements a standard 8:1 analog/digital multiplexer logic function with independent inhibit and 3-state disable controls. Its select inputs (A/B/C) decode binary addresses to route one of eight data channels (D0–D7) to the SEL OUTPUT pin, while INHIBIT forces output low and 3-STATE DISABLE places output in high-impedance state.

It uses metal-oxide-semiconductor (MOS) process technology with standardized symmetrical output characteristics, enabling direct interface with TTL and other CMOS buses. Quiescent current is fully tested per unit (≤150 µA @5 V, ≤3000 µA @20 V), and noise margin meets 1 V (5 V), 2 V (10 V), and 2.5 V (15 V) minimums.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	3 V to 20 V - supports wide-rail industrial and legacy 5/10/15 V logic systems
Output Drive Current	±3.2 mA @5 V - sufficient to directly drive 10 TTL loads or CMOS buses without buffering
Propagation Delay	55–120 ns @15 V - enables reliable operation up to ~5 MHz in synchronous bus applications
3-State Disable Time	20–40 ns @15 V - ensures fast bus release for time-critical arbitration and shared-line protocols
Input Leakage Current	±0.1 µA max @18 V - minimizes signal integrity degradation in high-impedance sensor or reference paths
Operating Temperature	−55 °C to +125 °C - qualified for under-hood automotive, power supply monitoring, and military-grade enclosures
Noise Margin	2.5 V min @15 V - provides robust immunity against EMI and crosstalk in noisy industrial environments

Pin/Terminal	Circuit Role	Design Meaning
1–7, 9	D0–D7 Data Inputs	Eight independent digital/analog input channels selected via A/B/C address lines
11–13	A, B, C Select Inputs	3-bit binary address determining which Dn channel routes to SEL OUTPUT
10	INHIBIT	Active-low control forcing SEL OUTPUT to logic low regardless of select state
15	3-STATE DISABLE	Active-low control placing SEL OUTPUT in high-impedance (Z) state for bus sharing
14	SEL OUTPUT	Single buffered output carrying selected Dn value or forced low/Z per control signals
8	VSS	Negative supply reference (ground or −V rail); required for proper CMOS threshold referencing
16	VDD	Positive supply input (3–20 V); powers internal logic and output stage

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar 8-channel data selector applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CD4512BE	Same logic function and pinout; wider package options (DIP-16 only), higher typical propagation delay (400 ns @5 V vs. 360 ns)	Limited to through-hole assembly; lacks SO-16 variant for space-constrained PCBs	Select when DIP packaging and legacy footprint compatibility are mandatory
MC14512BDR2G	Identical electrical specs and JEDEC compliance; tighter VOH tolerance (≥14.98 V @15 V) and lower max I_Q (120 µA @5 V)	Optimized for high-reliability aerospace use; extended traceability and lot-level testing	Select for mission-critical avionics where enhanced parametric consistency is required

Compared with CD4512BE and MC14512BDR2G, the HCF4512M013TR offers the only SO-16 option among these equivalents, enabling surface-mount production scalability while maintaining identical functional behavior and JEDEC B-series compatibility.

FAQ

Is HCF4512M013TR compatible with 5 V TTL logic levels?

Yes. At VDD = 5 V, the HCF4512M013TR guarantees VOH ≥4.95 V and VOL ≤0.05 V, exceeding TTL VIH (2.0 V) and VIL (0.8 V) thresholds. Input thresholds (VIH = 3.5 V, VIL = 1.5 V) also provide >1 V noise margin, ensuring reliable interfacing with standard TTL outputs and inputs without level shifters.

What is the maximum clock/data rate supported by HCF4512M013TR?

The device supports reliable operation up to approximately 5 MHz in typical bus applications. This is derived from worst-case propagation delay (360 ns @5 V) and 3-state disable time (120 ns), limiting minimum pulse width and setup/hold margins. For sustained 100% duty-cycle operation, design margins should limit frequency to ≤3 MHz at 5 V and ≤8 MHz at 15 V.

Can HCF4512M013TR be used for analog signal multiplexing?

Yes - it is specified for analog/digital signal routing. With R_ON not explicitly given but typical for B-series CMOS (≈100–300 Ω), and guaranteed VDD up to 20 V, it can pass DC-coupled signals within its supply rails. However, bandwidth is limited by 50 pF load capacitance and transition times (≤200 ns @5 V), making it suitable for audio-band and slow sensor signals but not RF or high-speed video.

Does HCF4512M013TR have built-in ESD protection?

Yes. Per STMicroelectronics' standard B-series CMOS process, the device includes gate-oxide protected inputs rated to ±2 kV HBM (Human Body Model) per JEDEC JESD22-A114. No external ESD diodes are required for typical board-level handling, though layout best practices (short traces, ground guard rings) are recommended for high-noise industrial environments.
