Product details
Overview
CD4541BM96G4 from Texas Instruments is a CMOS programmable timer IC with built-in RC oscillator, 16-stage binary counter, and selectable frequency division (2⁸ to 2¹⁶) or single-transition timing modes. It operates from 3V to 18V, supports external clock input on pin 3, and delivers symmetrical 100Ω output drive at 15V - used in precision power-on delay, retriggerable one-shot, and programmable interval timing circuits.
For engineers reviewing the CD4541BM96G4 datasheet, CD4541BM96G4 pinout, CD4541BM96G4 application, or CD4541BM96G4 equivalent, key selection considerations include its 14-pin SOIC package, AUTO/MASTER RESET control logic, Q/Q output polarity selection, RC oscillator tuning range (DC–100 kHz), and compatibility with TTL/Schottky/HTL loads across –55°C to +125°C.
Technical Context
The CD4541BM96G4 implements a 16-stage ripple counter driven by either an internal RC oscillator (tuned via RTC, CTC, RS) or external clock applied to pin 3. Its output stage selects Q or Q̅ from the 8th, 10th, 13th, or 16th stage using A/B inputs, with MODE (pin 10) determining continuous square-wave division or single-transition timing behavior.
Timing initialization uses AUTO RESET (pin 5) for power-on reset or MASTER RESET (pin 6) for manual reset; both disable the oscillator during reset to minimize quiescent current. The device features CMOS protection networks on all inputs and guarantees 100% tested IDD ≤ 100 μA at 20V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3V to 18V - supports wide industrial rail voltages without level-shifting |
| Oscillator Frequency Range | DC to 100 kHz - enables ultra-slow timing (e.g., hours-long delays) or fast event counting |
| Counter Stages | 16-stage binary counter - provides 2⁸ (256), 2¹⁰ (1024), 2¹³ (8192), or 2¹⁶ (65536) division ratios |
| Output Drive Capability | Drives 6 LPTTL, 3 LS, or 6 HTL loads - eliminates need for buffer stages in mixed-logic systems |
| Quiescent Current | ≤100 μA at 20V - enables battery-backed or low-power standby operation |
| Operating Temperature | –55°C to +125°C - qualified for military, automotive, and harsh-environment embedded use |
| Propagation Delay | 0.9–10.5 μs (VDD = 5–15V) - ensures predictable timing margins in synchronous designs |
Pinout & Package
CD4541BM96G4 is housed in a 14-pin SOIC (D) package, 3.90 mm × 8.65 mm body, 1.75 mm max height, with 1.27 mm pitch, RoHS-compliant NiPdAu lead finish, and MSL Level-1 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (RS) | Oscillator Bias Resistor | Provides bias current for internal oscillator; value affects stability and startup time |
| 3 (CLK) | External Clock Input | Accepts TTL/CMOS-compatible clock signal; overrides internal oscillator when used |
| 4 (NC) | No Connect | Not internally bonded; must remain unconnected per TI design guidelines |
| 5 (AR) | AUTO RESET Input | Logic 0 enables automatic power-on reset; logic 1 disables it to reduce quiescent current |

| 7 (VSS) | Ground Reference | System ground return; must be low-impedance for stable oscillator and counter operation |
| 8 (Q) | Inverted Output Terminal | Provides Q̅ output when Q/Q SELECT (pin 9) = high; complements pin 14's Q output |
| 9 (Q/Q SEL) | Output Polarity Select | Logic high selects Q̅ (pin 8); logic low selects Q (pin 14) - enables flexible logic-level interfacing |
| 10 (MODE) | Function Mode Control | Logic 0 = single-transition timer; logic 1 = continuous 2ᴺ frequency divider |
| 11 (NC) | No Connect | Not internally bonded; must remain unconnected |
| 12 (A) | Frequency Select Bit 0 | With B (pin 13), selects counter stage: 00=2¹³, 01=2¹⁰, 10=2⁸, 11=2¹⁶ |
| 13 (B) | Frequency Select Bit 1 | Paired with A (pin 12) to configure division ratio per Frequency Selection Table |
| 14 (VDD) | Positive Supply Rail | 3–18V CMOS supply; decoupling capacitor (0.1 μF) recommended near pin for noise immunity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable timer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4541BE | Same die, 14-pin PDIP package; higher θJA (80°C/W) vs SOIC's 86°C/W; no tape-and-reel option | Preferred for prototyping, through-hole assembly, or legacy board upgrades requiring socket compatibility | Select CD4541BE only when manual soldering or breadboard evaluation is required; not suitable for automated SMT production. |
| CD4541BNSR | Same functionality, 14-pin SOP package; slightly wider body (5.3mm vs SOIC 3.9mm); identical electrical specs and pinout | Used where board space allows larger footprint but requires same thermal profile and reflow compatibility as SOIC | Choose CD4541BNSR if existing PCB land pattern matches SOP NS outline or if preferred carrier tape size (2000/reel) aligns with procurement logistics. |
Compared with CD4541BE and CD4541BNSR, the CD4541BM96G4 offers optimized SMT manufacturability via SOIC-D package, standard 2500-piece tape-and-reel delivery, and industry-standard MSL-1 handling - making it the default choice for volume production of industrial timing modules.

FAQ
What is the maximum operating voltage for CD4541BM96G4?
The CD4541BM96G4 supports an absolute maximum supply voltage of +20V referenced to VSS, with guaranteed operation from 3V to 18V across the full –55°C to +125°C temperature range. At 20V, quiescent current is 100% tested to ensure reliability under overvoltage transients common in industrial power systems.
Can CD4541BM96G4 operate without external timing components?
No - the CD4541BM96G4 requires external RTC, CTC, and RS components to configure its internal RC oscillator. However, it can accept an external clock signal on pin 3, bypassing the RC network entirely. In that mode, CD4541BM96G4 functions solely as a 16-stage counter/divider with no oscillator dependency.
How does AUTO RESET differ from MASTER RESET on CD4541BM96G4?
AUTO RESET (pin 5) enables automatic initialization at power-on when pulled low; MASTER RESET (pin 6) provides manual, edge-triggered reset. When AUTO RESET is enabled, CD4541BM96G4 draws additional current (up to 500 μA at 15V), so it should be disabled (pin 5 = high) in low-power applications where reset is managed externally.
Which output pin provides the non-inverted signal on CD4541BM96G4?
Pin 14 (OUTPUT) delivers the non-inverted Q signal when Q/Q SELECT (pin 9) is held low. Pin 8 provides the complementary Q̅ output. This dual-output architecture allows CD4541BM96G4 to drive both true and complement logic paths simultaneously without external inverters.
Is CD4541BM96G4 compatible with modern 3.3V logic systems?
Yes - although optimized for 5V–15V operation, CD4541BM96G4 meets JEDEC B-Series specifications and functions reliably at 3V minimum supply. Input thresholds scale with VDD, and output VOH/VOL remain valid down to 3V, enabling direct interface with 3.3V microcontrollers when appropriate pull-ups or level translators are used for marginal cases.
