Product details
Overview
74LVC163PW,118 from Nexperia is a presettable synchronous 4-bit binary counter with internal look-ahead carry, synchronous reset (MR), parallel load (PE), and terminal count (TC) output. It operates from 1.2 V to 3.6 V, supports 150 MHz max clock frequency at 3.3 V, and features dual count-enable inputs (CEP/CET) for seamless n-bit cascading in timing and control circuits.
For engineers reviewing the 74LVC163PW,118 datasheet, 74LVC163PW,118 pinout, 74LVC163PW,118 application, or 74LVC163PW,118 equivalent, this device is selected for high-speed digital logic design requiring deterministic preset, synchronous reset, and low-voltage compatibility with mixed-supply systems and TTL-level interfacing.
Technical Context
The 74LVC163PW,118 implements four edge-triggered D-type flip-flops with synchronous clocking on the rising edge of CP. Its functional behavior is fully defined by the MR, PE, CEP, and CET control signals - all sampled synchronously relative to CP, enabling glitch-free state transitions and predictable timing margins.
Look-ahead carry generation occurs internally via combinational logic feeding TC, which asserts HIGH only when CET = HIGH and Q0–Q3 = HHHH (15dec). Cascading is enabled by routing TC to CET of the next stage, with propagation delay tPHL(CP→TC) as low as 3.8 ns at VCC = 3.3 V, supporting multi-stage counters up to 120 MHz at full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | LVC (Low-Voltage CMOS) - enables 1.2 V–3.6 V operation with 5.5 V-tolerant inputs |
| Counter Type | Synchronous 4-bit binary - all outputs update simultaneously on CP rising edge |
| Max Clock Frequency | 150 MHz at VCC = 3.3 V, -40 °C to +85 °C - defines maximum counting rate in high-speed sequencers |
| Terminal Count (TC) | Single-cycle HIGH pulse synchronized to Q0 - directly drives CET of next stage without external gating |
| Supply Voltage Range | 1.2 V to 3.6 V - supports battery-powered, low-power embedded, and mixed-voltage I/O domains |
| Input Voltage Tolerance | Inputs accept up to 5.5 V - allows direct interface with 5 V TTL logic without level shifters |
| Operating Temperature | -40 °C to +125 °C - qualified for automotive under-hood and industrial control environments |
Pinout & Package
TSSOP16 plastic thin shrink small outline package (SOT403-1); 16-pin, 4.4 mm body width; lead pitch 0.65 mm; exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (MR) | Synchronous master reset | Active-LOW; resets Q0–Q3 to 0000 on next CP rising edge - enables precise zero-synchronization across clock domains |
| 2 (CP) | Clock input | Rising-edge triggered; clocks all four flip-flops and load logic simultaneously - eliminates ripple delay and metastability in cascaded stages |
| 3–6 (D0–D3) | Data inputs | Parallel load data bus; loaded into Q0–Q3 when PE = LOW and CP rises - supports arbitrary initial count values |
| 7 (CEP) | Count enable (parallel) | Enables counting only when HIGH; must be HIGH with CET for increment operation - provides hierarchical enable control |
| 8 (GND) | Ground reference | 0 V return path for all internal logic and I/O - requires low-inductance connection to minimize ground bounce |
| 9 (PE) | Parallel enable | Active-LOW; forces parallel load regardless of CEP/CET state - decouples preset function from count enable logic |
| 10 (CET) | Count enable (terminal) | Enables TC output; fed forward to next stage's CET - simplifies serial cascade wiring and timing analysis |
| 11–14 (Q0–Q3) | Counter outputs | Binary-weighted outputs (LSB to MSB); Q0 toggles every CP, Q3 toggles every 16th CP - provides standard binary sequence for address generation or state encoding |
| 15 (TC) | Terminal count output | HIGH only when CET = HIGH and Q0–Q3 = 1111; pulse width ≈ Q0 HIGH time - serves as carry-out for multi-stage counters |
| 16 (VCC) | Supply voltage | 1.2 V–3.6 V power rail; bypass capacitor required near pin for stable high-speed switching |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous reset and load | Eliminates race conditions and ensures deterministic state transitions on every clock edge |
| Look-ahead carry (TC) | Reduces inter-stage propagation delay in multi-counter chains - enables >100 MHz system clock rates |
| 5.5 V-tolerant inputs | Permits direct connection to legacy 5 V logic without external level translators or resistive dividers |
| JEDEC-compliant voltage ranges | Validated per JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V) |
| ESD robustness | HBM >2000 V and CDM >1000 V - enhances reliability in automated PCB assembly and field-deployed equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-bit synchronous counter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC161PW,118 | Asynchronous reset (MR active-LOW, but resets immediately - no clock dependency) | Less suitable for clock-domain crossing; cannot guarantee simultaneous reset across multi-chip systems | Select when immediate reset response is prioritized over synchronous timing integrity |
| SN74LV163APW | TI variant with identical logic but different AC/DC specs: fmax = 120 MHz at VCC = 3.3 V, wider VCC tolerance (1.65–5.5 V) | Higher supply voltage flexibility but lower max speed; not drop-in for 150 MHz designs | Select when operating above 3.6 V or requiring TI-qualified supply chain continuity |
Compared with 74LVC161PW,118, the 74LVC163PW,118 offers superior timing predictability in synchronous systems; versus SN74LV163APW, it delivers higher speed at 3.3 V but narrower voltage headroom - critical for low-power, high-frequency embedded counters.

FAQ
What is the minimum supply voltage for guaranteed operation of the 74LVC163PW,118?
The 74LVC163PW,118 is specified for reliable operation down to 1.2 V, with full functionality including setup/hold timing, propagation delays, and output drive strength maintained across the -40 °C to +125 °C range. Below 1.2 V, parameters such as tpd and IOH/IOL are not guaranteed per the datasheet.
Can the 74LVC163PW,118 be used with a 5 V microcontroller I/O port?
Yes - all inputs (MR, CP, D0–D3, PE, CEP, CET) are 5.5 V tolerant, allowing direct connection to 5 V GPIO without level-shifting circuitry. Outputs (Q0–Q3, TC) swing rail-to-rail between GND and VCC, so a 3.3 V VCC configuration yields 3.3 V logic-high levels compatible with 5 V-tolerant MCU inputs.
How does the synchronous reset (MR) differ from asynchronous reset in similar counters?
The MR input of the 74LVC163PW,118 is synchronous: Q0–Q3 transition to 0000 only on the next rising edge of CP after MR goes LOW. This prevents metastability and ensures clean state transitions aligned to the system clock - unlike asynchronous reset, which can cause unpredictable glitches if asserted mid-cycle.
Is the TSSOP16 package (SOT403-1) RoHS and REACH compliant?
Yes - the 74LVC163PW,118 in TSSOP16 (SOT403-1) packaging meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound. Compliance documentation is available through Nexperia's product change notifications and material declarations portal.
