Product details
Overview
74HC393PW-Q100 from Nexperia is an automotive-qualified dual 4-bit binary ripple counter IC with independent clock and master reset inputs per counter, operating from 2.0 V to 6.0 V supply, delivering up to 107 MHz max clock frequency at 6.0 V, and featuring CMOS-level input thresholds for low-power logic interfacing in engine control units and body electronics.
For engineers reviewing the 74HC393PW-Q100 datasheet, 74HC393PW-Q100 pinout, 74HC393PW-Q100 application, or 74HC393PW-Q100 equivalent, this device supports precise frequency division (÷2 to ÷256), asynchronous reset timing validation, automotive-grade thermal reliability (−40 °C to +125 °C), and TSSOP14 package compatibility with AOI-enabled solder joint inspection.
Technical Context
This dual ripple counter implements two independent 4-stage asynchronous binary counters, each advancing on the HIGH-to-LOW clock edge (nCP) and clearing synchronously via active-HIGH nMR. Its cascaded flip-flop architecture inherently introduces propagation delay between output bits (e.g., 4–12 ns nQx→nQ(x+1) at VCC = 6.0 V), limiting maximum usable clock rate in synchronous systems but enabling simple divide-by-N configurations without external feedback logic.
Input clamp diodes allow safe interface to voltages exceeding VCC when used with current-limiting resistors, while AEC-Q100 Grade 1 qualification ensures robustness against automotive transients and temperature cycling. The device complies with JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards, supporting mixed-voltage system integration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Dual 4-bit asynchronous binary ripple counter - provides two independent ÷2⁴ (÷16) divisions in one package, enabling ÷256 total division with inter-counter cascading. |
| Supply Voltage Range | 2.0 V to 6.0 V - supports direct interface with 3.3 V and 5 V logic families without level shifters. |
| Max Clock Frequency | 107 MHz at VCC = 6.0 V (CL = 50 pF) - defines upper limit for single-counter operation before cumulative ripple delay causes timing failure. |
| Propagation Delay (nCP → nQ0) | 12–21 ns at VCC = 6.0 V - determines minimum clock period for reliable first-bit capture in timing-critical applications. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive environments including powertrain and chassis control modules. |
| Input Thresholds | CMOS-level (VIH = 4.2 V, VIL = 1.8 V at VCC = 6.0 V) - ensures noise margin >1.2 V and compatibility with standard HC logic outputs. |
| Power Dissipation | 8.0 μA ICC typical at VCC = 6.0 V - enables ultra-low static power in always-on vehicle subsystems such as wake-up timers. |
Pinout & Package
TSSOP14 plastic thin shrink small outline package (SOT402-1); 14 leads; body width 4.4 mm; side-wettable flanks for automated optical inspection (AOI) of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1CP | Counter 1 clock input - edge-triggered on HIGH-to-LOW transition; initiates ripple through Q0–Q3 chain. |
| 2 | VCC | Main supply voltage input - powers both counters and output buffers; requires local decoupling near pin. |
| 3 | 1MR | Counter 1 master reset - active HIGH asynchronous clear; forces 1Q0–1Q3 LOW independent of clock state. |
| 4 | 2CP | Counter 2 clock input - functionally identical to 1CP; enables independent timing control for dual-channel division. |
| 5 | 1Q0 | Counter 1 bit-0 output - LSB of first 4-bit counter; toggles on every 1CP edge, providing ÷2 signal. |
| 6 | 2MR | Counter 2 master reset - active HIGH asynchronous clear; isolated from Counter 1 for flexible reset sequencing. |
| 7 | 1Q1 | Counter 1 bit-1 output - toggles every two 1CP edges; provides ÷4 division relative to 1CP. |
| 8 | 2Q0 | Counter 2 bit-0 output - LSB of second counter; enables parallel frequency division paths. |
| 9 | 1Q2 | Counter 1 bit-2 output - toggles every four 1CP edges; yields ÷8 division from 1CP. |
| 10 | 2Q1 | Counter 2 bit-1 output - provides independent ÷4 signal synchronized to 2CP. |
| 11 | 1Q3 | Counter 1 bit-3 output - MSB of first counter; toggles every 16 clocks (÷16), completing full 4-bit range. |
| 12 | 2Q2 | Counter 2 bit-2 output - delivers ÷8 division referenced to 2CP; supports multi-rate timing generation. |
| 13 | GND | Ground reference - return path for all internal logic and output currents; must be low-impedance connection. |
| 14 | 2Q3 | Counter 2 bit-3 output - MSB of second counter; provides second independent ÷16 output for dual-channel systems. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use across −40 °C to +125 °C ambient, meeting stringent reliability and lifetime requirements for engine control and ADAS modules. |
| Independent dual-clock architecture | Enables simultaneous but non-synchronized counting on two channels - critical for generating asymmetric timing signals in lighting control or sensor sampling. |
| Asynchronous master reset per counter | Allows selective zeroing of either 4-bit counter without affecting the other, simplifying state recovery in fault-tolerant automotive firmware. |
| Clamp diode-equipped inputs | Permits safe interfacing to voltages >VCC (e.g., 12 V sensor lines) using series resistors - eliminates need for external protection circuitry. |
| TSSOP14 with side-wettable flanks | Supports automated optical inspection (AOI) of solder joints during SMT assembly - improves yield and traceability in automotive manufacturing. |
Applications
| Engine Control Unit (ECU) Timing | Automotive Lighting Sequencing |
|---|---|
|

| Body Control Module (BCM) Wake-Up Timer | Infotainment System Clock Division |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-bit binary counter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT393PW-Q100 | TTL-compatible inputs (VIH = 2.0 V min at VCC = 4.5–5.5 V) vs. CMOS inputs on 74HC393PW-Q100; otherwise identical pinout, timing, and packaging. | Better suited for interfacing directly with legacy 5 V TTL logic or microcontrollers lacking 3.3 V–compatible outputs. | Select when driving from 5 V microcontrollers without level shifters; avoid if system uses mixed 3.3 V/5 V supplies where HC thresholds improve noise immunity. |
| SN74LV393APWR | Lower VCC range (2.0–5.5 V), higher max fCLK (120 MHz at 5 V), but not AEC-Q100 qualified; TSSOP14 package (same footprint). | Limited to industrial or consumer infotainment modules where automotive qualification is unnecessary. | Choose for cost-sensitive non-automotive designs requiring higher speed; reject for any safety-critical or under-hood deployment. |
Compared with 74HCT393PW-Q100, the HC variant offers superior noise immunity in mixed-signal automotive environments, while SN74LV393APWR trades qualification for speed - making the 74HC393PW-Q100 optimal for AEC-compliant timing where CMOS input compatibility and thermal robustness are prioritized.

FAQ
What is the maximum clock frequency supported by the 74HC393PW-Q100?
The 74HC393PW-Q100 supports up to 107 MHz at VCC = 6.0 V with CL = 50 pF, as specified in Table 7 of the datasheet. This value represents the highest guaranteed clock rate for reliable nCP → nQ0 propagation; actual usable frequency in ripple-chain configurations is lower due to cumulative delays across Q0–Q3 stages.
Can the two counters be cascaded to form an 8-bit counter?
Yes - the 74HC393PW-Q100 supports cascading by connecting 1Q3 to 2CP, enabling an 8-bit ÷256 counter. However, propagation delay accumulates (e.g., ~24 ns additional delay from 1Q3 to 2Q0), limiting maximum effective clock rate and introducing ripple-induced timing skew unsuitable for synchronous register applications.
Does the 74HC393PW-Q100 require external pull-up or pull-down resistors on its inputs?
No - the device includes integrated input clamp diodes and has defined VIH/VIL thresholds (e.g., VIH = 4.2 V at VCC = 6.0 V). Inputs should be actively driven to valid logic levels; floating inputs are undefined and may cause excessive ICC or metastability, so unused inputs must be tied to VCC or GND.
How does the 74HC393PW-Q100 differ from the 74HC393D-Q100?
The 74HC393PW-Q100 uses a TSSOP14 package (SOT402-1) with side-wettable flanks for AOI, while the 74HC393D-Q100 uses SO14 (SOT108-1). Both share identical electrical specifications, AEC-Q100 qualification, and pinout, but the TSSOP version offers smaller footprint and enhanced manufacturability in high-density automotive PCBs.
