Product details
Overview
74HC163PW,112 from Nexperia is a synchronous presettable 4-bit binary counter with internal look-ahead carry, synchronous reset (active LOW on MR), and dual count-enable inputs (CEP/CET) for cascading. It operates at up to 55 MHz (VCC = 6.0 V), supports CMOS-level inputs, and delivers glitch-free counting in industrial temperature range (−40 °C to +125 °C). Used in digital timing control, address generation, and modulo-N counter design.
For engineers reviewing the 74HC163PW,112 datasheet, 74HC163PW,112 pinout, 74HC163PW,112 application, or 74HC163PW,112 equivalent, this device is selected for synchronous load-and-count precision, deterministic terminal count (TC) pulse timing, low-power 74HC logic compatibility, and TSSOP16 footprint suitability in space-constrained PCB layouts.
Technical Context
The 74HC163PW,112 implements four edge-triggered D-type flip-flops clocked synchronously on the positive-going edge of CP. Counting occurs only when both CEP and CET are HIGH; TC asserts HIGH only at terminal count (Q3–Q0 = 1111) while CET remains HIGH - enabling precise ripple-carry chaining without race conditions.
Parallel loading is unconditional: a LOW on PE forces D0–D3 into Q0–Q3 on the next CP edge, overriding CE states. Synchronous reset via MR clears all outputs to LOW after one CP edge, allowing clean modulus reconfiguration using external NAND logic - eliminating asynchronous reset metastability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74HC CMOS - compatible with 2.0 V to 6.0 V supply; TTL-input-compatible variant is 74HCT163. |
| Count Width | 4-bit binary (0 to 15); terminal count (TC) pulses on Q3Q2Q1Q0 = 1111. |
| Max Clock Frequency | 55 MHz at VCC = 6.0 V - enables high-speed timing in digital control loops. |
| Propagation Delay | CP to Qn: 16 ns (typ), CP to TC: 20 ns (typ) at VCC = 6.0 V - ensures tight timing margins in cascaded counters. |
| Supply Range | 2.0 V to 6.0 V - supports battery-powered and mixed-voltage system integration. |
| Operating Temperature | −40 °C to +125 °C - qualified for automotive under-hood and industrial motor-control environments. |
| Package | TSSOP16 (SOT403-1), 4.4 mm body width - surface-mount, fine-pitch footprint for compact PCBs. |
Pinout & Package
TSSOP16 plastic thin shrink small outline package (SOT403-1), 16-pin, 0.65 mm pitch, 4.4 mm body width, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 MR | Synchronous master reset | Active-LOW; clears Q0–Q3 to 0000 on next CP rising edge - enables deterministic modulus reconfiguration. |
| 2 CP | Clock input | Positive-edge triggered; all flip-flops update simultaneously - eliminates ripple delay and output glitches. |
| 3–6 D0–D3 | Data inputs | Loaded into Q0–Q3 when PE = LOW - supports programmable initial state for non-power-of-two counters. |
| 7 CEP | Count enable parallel | Enables counting only when HIGH; used with CET to gate count action - essential for multi-stage enable logic. |
| 8 GND | Ground reference | 0 V return path for logic and power - must be low-impedance to maintain noise margin. |
| 9 PE | Parallel enable | Active-LOW; forces synchronous load regardless of CEP/CET state - decouples preset control from count gating. |
| 10 CET | Count enable carry | Enables TC output and feeds forward to next stage - required HIGH for TC assertion and cascade enable. |
| 11–14 Q3–Q0 | Flip-flop outputs | Q0 LSB to Q3 MSB; outputs reflect current count value - used for feedback, decode, or display drivers. |
| 15 TC | Terminal count output | HIGH pulse ≈ duration of Q0 HIGH - directly clocks next cascaded counter stage without external delay compensation. |
| 16 VCC | Supply voltage | 2.0 V to 6.0 V; powers all logic - bypassing with 100 nF ceramic near pin critical for stable high-frequency operation. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous reset | Eliminates metastability and race conditions during modulus change - no external debounce or synchronization logic needed. |
| Look-ahead carry | TC output enables next-stage clock without propagation delay accumulation - supports >16-bit counters with uniform timing. |
| Two independent count enables | CEP and CET allow hierarchical enable control - e.g., CEP driven by system enable, CET by upstream TC - simplifying complex sequencing. |
| CMOS input levels | VIH = 3.15 V (min at VCC = 4.5 V); permits direct interfacing with 3.3 V microcontrollers without level shifters. |
| ESD protection | HBM > 2000 V, MM > 200 V - enhances robustness during board assembly and field handling. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT163PW,112 | TTL-compatible inputs (VIH = 2.0 V min); identical pinout, timing, and function. | Better suited for mixed 5 V TTL/CMOS systems; higher input drive capability but slightly higher ICC. | Select when interfacing legacy 5 V TTL logic or driving heavier capacitive loads. |
| SN74LS163N | Bipolar TTL technology; 4.75–5.25 V only; slower (max 30 MHz); higher power (ICC ≈ 30 mA). | Limited to 5 V systems; incompatible with 3.3 V logic; requires pull-ups on open-collector outputs. | Choose only for drop-in replacement in legacy LS-based designs where voltage and speed constraints permit. |
Compared with 74HCT163PW,112, the 74HC163PW,112 offers lower static power and wider VCC range but requires CMOS-level drive; versus SN74LS163N, it delivers 80% higher speed and 95% lower quiescent current at 5 V, with full 3.3 V compatibility.

FAQ
What is the minimum supply voltage for reliable operation of the 74HC163PW,112?
The 74HC163PW,112 is specified down to 2.0 V per its recommended operating conditions. At VCC = 2.0 V, VIH is 1.5 V (min), VOL is 0.1 V (max), and fmax is 6 MHz - sufficient for low-power battery-operated counters. Operation below 2.0 V risks undefined logic states and increased propagation delay.
Can the 74HC163PW,112 be used to build a modulo-10 counter without external gates?
No - the 74HC163PW,112 has fixed modulo-16 behavior and requires external combinational logic (e.g., NAND gate decoding Q3Q1) to force synchronous reset at count=9. Its synchronous reset (MR) and parallel load (PE) enable clean modulo-N implementation, but no internal modulus programming capability exists.
How does the TC output behave when CET is LOW?
When CET is LOW, the TC output remains LOW regardless of counter state - even at Q3Q2Q1Q0 = 1111. TC only goes HIGH when both CET = HIGH and the counter reaches terminal count, making it safe for cascading: upstream TC can directly drive downstream CET without risk of spurious enable.
Is the TSSOP16 package of 74HC163PW,112 compatible with standard reflow profiles?
Yes - the 74HC163PW,112 in SOT403-1 (TSSOP16) is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports standard Pb-free reflow profiles (peak 260 °C, 60 s max above 217 °C). Its 0.65 mm pitch and exposed pad-free construction ensure reliable solder joint formation with standard stencil design.
