Product details
Overview
HCF4041UM013TR from STMicroelectronics is a quad true/complement buffer IC in SOP-14 package, featuring symmetrical sourcing/sinking drive (±12.1 mA at VDD=15V), equalized propagation delay (25–50 ns), and operation across 3–20 V supply. It serves as a CMOS-to-TTL level translator and ultra-low-power resistor network driver in precision data conversion systems.
For engineers reviewing the HCF4041UM013TR datasheet, HCF4041UM013TR pinout, HCF4041UM013TR application, or HCF4041UM013TR equivalent, key selection criteria include balanced sink/source capability, input leakage ≤0.1 µA at 18 V, quiescent current ≤600 µA at 20 V, and guaranteed noise margin ≥2.5 V at 15 V operation.
Technical Context
The HCF4041UM013TR integrates four independent CMOS transmission-gate-based buffer pairs, each delivering true and complement outputs simultaneously with matched tPLH/tPHL delay (e.g., 25–50 ns at VDD=15V). Its n- and p-channel output stage enables bidirectional current drive up to ±12.1 mA per output.
It operates over full industrial temperature range (−55°C to +125°C) with supply voltage flexibility (3–20 V), specified DC parameters including VIH/VIL thresholds scaled to VDD (e.g., VIH = 12.5 V min at VDD=15V), and input capacitance of 22.5 pF max.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 20 V - supports single-supply operation across 5 V, 10 V, and 15 V logic domains |
| Output Drive Current | ±12.1 mA at VDD=15 V - sufficient for driving TTL loads and resistive networks without external buffers |
| Propagation Delay | 25–50 ns at VDD=15 V, CL=50 pF - ensures timing predictability in synchronous data paths |
| Input Leakage Current | ≤0.1 µA at VDD=18 V - preserves signal integrity in high-impedance A/D reference networks |
| Quiescent Current | ≤600 µA at VDD=20 V, TA=125°C - enables low-power standby in battery-backed instrumentation |
| Noise Margin | ≥2.5 V at VDD=15 V - provides robust immunity against EMI in industrial control environments |
| Input Capacitance | 22.5 pF max - limits capacitive loading on preceding CMOS stages in multi-stage buffers |
Pinout & Package
SOP-14 (SO-14) package per mechanical drawing PO13G: 8.55–8.75 mm body width, 5.8–6.2 mm body length, 1.27 mm lead pitch, gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 3, 6, 10, 13 | Data Inputs (A, B, C, D) | CMOS-compatible inputs accepting 0–VDD logic levels; high-impedance, low-leakage nodes |
| 1, 4, 8, 11 | True Outputs (E, G, K, M) | Non-inverting buffered outputs; actively driven high/low with matched rise/fall times |
| 2, 5, 9, 12 | Complement Outputs (F, H, L, N) | Inverting buffered outputs; simultaneous with true outputs, equalized delay path |
| 7 | VSS | Negative supply reference (typically ground); return path for all output currents |
| 14 | VDD | Positive supply rail; powers all four buffer channels and defines logic threshold scaling |
Key Features
| Feature | Design Value |
|---|---|
| Balanced sink/source drive | ±12.1 mA at VDD=15 V - eliminates need for external pull-up/pull-down resistors in mixed-logic interfaces |
| Equalized true/complement delay | tPLH/tPHL match within 5 ns at 15 V - critical for skew-sensitive applications like differential clock distribution |
| Wide supply range support | 3–20 V operation with parametric ratings at 5/10/15 V - simplifies design reuse across legacy and upgraded power rails |
| Ultra-low input leakage | ≤0.1 µA at 18 V - maintains accuracy in high-resolution ADC reference buffers and sensor front-ends |
| 100% quiescent current tested | Guaranteed IDD ≤600 µA at 20 V/125°C - ensures reliability in thermally constrained embedded modules |
Applications
| ADC Reference Buffering | TTL-Level Translation |
|---|---|
Use Scenario: Driving precision resistor ladder networks in 12-bit successive-approximation ADCs. IC Role / Device Role / Timing Role: Quad true/complement buffer isolates reference voltage source while providing matched drive to ladder taps. Use Value: Equalized delay and low leakage (<0.1 µA) prevent code-dependent offset errors and maintain monotonicity. | Use Scenario: Interfacing 15 V CMOS microcontrollers to 5 V TTL peripherals in industrial PLC I/O modules. IC Role / Device Role / Timing Role: Level-shifting buffer with bidirectional drive capability and noise margin ≥2.5 V.

| Differential Clock Distribution | Transmission Line Driver |
Use Scenario: Generating complementary clock pairs for dual-edge-triggered logic in test equipment timing generators. IC Role / Device Role / Timing Role: Simultaneous true/complement output generator with <5 ns skew between outputs. Use Value: Matched tPLH/tPHL ensures deterministic setup/hold margins for downstream flip-flops. | Use Scenario: Driving 50 Ω coaxial cables in automated test fixture signal routing. IC Role / Device Role / Timing Role: Low-capacitance (22.5 pF), fast-transition (15–30 ns) line driver with controlled edge rates. Use Value: Minimizes reflections and overshoot; ±12.1 mA drive sustains signal amplitude over 1 m cable run. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad true/complement buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4041UBM96 | TI variant; identical pinout and AC specs, but VOH/VOL tested at lower current (±3.2 mA vs ±12.1 mA) | Limited to light-load TTL interfacing; not recommended for resistor ladder or transmission line drive | Select when only basic level translation is needed and supply is fixed at 5 V or 10 V |
| MC14041BDR2G | ON Semiconductor version; same SO-14 package, but quiescent current higher (1.2 mA max at 20 V/125°C) | Higher static power limits use in battery-powered portable instruments with strict sleep-current budgets | Prefer where second-source assurance is required and thermal derating allows higher IDD |
Compared with CD4041UBM96 and MC14041BDR2G, the HCF4041UM013TR delivers superior drive strength and lower leakage-critical for precision analog interface and high-noise-margin digital translation-while maintaining full pin and functional compatibility.

FAQ
Is HCF4041UM013TR pin-compatible with through-hole DIP-14 versions?
Yes, the SOP-14 package (HCF4041UM013TR) shares identical pin numbering and function mapping with the DIP-14 variant (HCF4041UBEY), including VDD (pin 14), VSS (pin 7), and paired true/complement outputs. Mechanical layout differs, but PCB footprint adaptation is straightforward using standard SO-to-DIP adapter guidelines.
What is the maximum capacitive load this device can drive reliably?
The HCF4041UM013TR is characterized up to 50 pF (CL = 50 pF) in dynamic testing, with transition times of 15–30 ns at VDD = 15 V. For loads exceeding 50 pF, output rise/fall times increase linearly; sustained drive above 100 pF may cause excessive transition time (>100 ns) and reduced noise margin-external buffering is recommended beyond that point.
Does this part support 3.3 V logic systems?
Yes, the HCF4041UM013TR operates down to 3 V supply, with verified VIH = 2.0 V min and VIL = 1.0 V max at VDD = 3.3 V (interpolated from 3 V/5 V data). However, output drive drops to ±1.02 mA, and noise margin reduces to ~0.7 V-suitable for low-speed, short-trace 3.3 V CMOS interfacing but not for driving TTL or long traces.
Why does the datasheet list this as "Obsolete Product(s)"?
STMicroelectronics marked the HCF4041UB family as obsolete in 2001 due to end-of-life for the B-series CMOS process node. However, HCF4041UM013TR remains available through authorized distributors and Aetrix Electronics' legacy component program, with full traceability, lot-controlled inventory, and technical support for existing designs requiring long-term supply continuity.
