Product details
Overview
74HC193D-Q100 from Nexperia is a presettable synchronous 4-bit binary up/down counter with separate CPU and CPD clock inputs, asynchronous master reset (MR), asynchronous parallel load (PL), and active-low terminal count outputs (TCU/TCD). It operates from 2.0 V to 6.0 V, supports -40 °C to +125 °C, and is AEC-Q100 Grade 1 qualified for automotive applications such as gear position tracking and odometer logic.
For engineers reviewing the 74HC193D-Q100 datasheet, 74HC193D-Q100 pinout, 74HC193D-Q100 application, or 74HC193D-Q100 equivalent, key selection considerations include its dual-edge-triggered counting mode, TTL-compatible input option (74HCT variant), propagation delay down to 18 ns at 6 V, and SO16 package compatibility with legacy PCB footprints.
Technical Context
This device implements four edge-triggered D-type flip-flops with synchronous up/down control logic, where CPU and CPD are independently gated - only one may be HIGH during operation to ensure deterministic state transitions. Count direction is determined by which clock line receives the LOW-to-HIGH transition while the other remains HIGH.
Terminal count outputs TCU and TCD replicate the respective clock waveforms (active LOW) and enable cascading without external logic: TCU pulses on overflow (15→0), TCD pulses on underflow (0→15). Asynchronous PL and MR override all clock activity, loading data or clearing outputs regardless of clock state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | 4-bit synchronous binary up/down counter with parallel load and master reset |
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct interface with 3.3 V and 5 V logic domains |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive use |
| Max Clock Frequency | 24 MHz at VCC = 6.0 V - supports real-time speedometer or tachometer update rates |
| Propagation Delay | 18 ns (CPU/CPD to Qn, VCC = 6.0 V) - ensures tight timing margins in multistage counters |
| Input Logic Type | CMOS-level inputs (74HC variant); compatible with 3.3 V microcontroller GPIOs |
| Output Drive | ±4.0 mA at VCC = 4.5 V - sufficient to drive multiple 74-series inputs or small LED indicators |
Pinout & Package
Package: SO16 plastic small outline package (SOT109-1), 16-pin, 3.9 mm body width, lead pitch 1.27 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9, 10, 15 | D0–D3 | Asynchronous parallel data inputs - loaded into counter when PL is LOW, independent of clocks |
| 2, 3, 6, 7 | Q0–Q3 | 4-bit binary output - reflects current count value; used for display or feedback to controller |
| 4 | CPD | Count-down clock input - LOW-to-HIGH edge triggers decrement when CPU = HIGH |
| 5 | CPU | Count-up clock input - LOW-to-HIGH edge triggers increment when CPD = HIGH |
| 8 | GND | Ground reference - must be low-impedance return path for all internal switching currents |
| 11 | PL | Active-LOW parallel load enable - forces immediate latching of D0–D3 regardless of clock state |
| 12 | TCU | Active-LOW terminal count up - goes LOW on 15→0 transition; duplicates CPU waveform for cascade |
| 13 | TCD | Active-LOW terminal count down - goes LOW on 0→15 transition; duplicates CPD waveform for cascade |
| 14 | MR | Active-HIGH master reset - forces Q0–Q3 = 0000; overrides PL, clocks, and data |
| 16 | VCC | Positive supply - powers internal CMOS circuitry; requires local 100 nF decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous reversible counting | Eliminates ripple delay between stages - all Q outputs change simultaneously on clock edge |
| Asynchronous parallel load | Enables instant preset to any 4-bit value (e.g., start at 13 for gear position initialization) |
| Asynchronous master reset | Guarantees known zero state on power-up or fault recovery without waiting for clock edge |
| Expandable cascade architecture | TCU/TCD outputs directly drive CPU/CPD of next stage - no glue logic required for multi-digit counters |
| AEC-Q100 Grade 1 qualification | Validated for automotive environments including thermal cycling, humidity, and ESD robustness |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-bit synchronous up/down counter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT193D-Q100 | TTL-compatible inputs (VIH = 2.0 V min), identical pinout and function | Better suited for mixed 5 V TTL/CMOS systems; higher input current draw vs. 74HC | Select when interfacing legacy 5 V microcontrollers with standard TTL thresholds |
| SN74LS193N | Bipolar TTL technology, 4.75–5.25 V only, slower (max 25 MHz), no AEC-Q100 qualification | Limited to commercial temperature range (-40 °C to +85 °C); higher power consumption | Use only in non-automotive, cost-sensitive 5 V designs where qualification is not required |
Compared with 74HCT193D-Q100, this 74HC variant offers lower static current and wider voltage flexibility; versus SN74LS193N, it delivers automotive-grade reliability, extended temperature support, and 30% faster max frequency at 6 V.

FAQ
What is the difference between 74HC193D-Q100 and 74HCT193D-Q100?
The 74HC193D-Q100 uses CMOS-level inputs (VIH ≥ 70% VCC), while the 74HCT193D-Q100 features TTL-compatible inputs (VIH ≥ 2.0 V at VCC = 4.5–5.5 V). Both share identical pinout, function, AEC-Q100 qualification, and SO16 packaging. The HCT version simplifies interfacing with legacy 5 V TTL outputs but draws higher input current.
Can 74HC193D-Q100 operate at 3.3 V?
Yes - the 74HC193D-Q100 is fully specified from 2.0 V to 6.0 V. At 3.3 V, it delivers typical propagation delay of 25 ns (CPU to Qn), VIH = 2.31 V min, and VOL ≤ 0.26 V at 4 mA sink, making it compatible with 3.3 V microcontrollers without level shifters.
How do I cascade multiple 74HC193D-Q100 devices for an 8-bit counter?
Connect TCU of the LSB stage to CPD of the MSB stage for up-counting, and TCD of LSB to CPU of MSB for down-counting. Ensure CPU and CPD of each stage are never both HIGH simultaneously. Use common MR and PL lines for synchronized reset/load across stages.
Is the SO16 package (SOT109-1) RoHS and REACH compliant?
Yes - Nexperia confirms the 74HC193D-Q100 in SOT109-1 packaging meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound, as documented in Nexperia's official compliance statements.
