Product details
Overview
74HC163D-Q100 from Nexperia is a synchronous presettable 4-bit binary counter with internal look-ahead carry, synchronous reset (MR), parallel load (PE), and dual count-enable inputs (CEP/CET) for cascading. It operates at up to 55 MHz (VCC = 6.0 V), supports automotive-grade temperature range (−40 °C to +125 °C), and delivers glitch-free counting in engine control timing circuits.
For engineers reviewing the 74HC163D-Q100 datasheet, 74HC163D-Q100 pinout, 74HC163D-Q100 application, or 74HC163D-Q100 equivalent, this device is selected for deterministic modulo-N counter design, clock-synchronized state loading, and automotive powertrain timing where AEC-Q100 Grade 1 compliance and synchronous reset behavior are mandatory.
Technical Context
The 74HC163D-Q100 implements four edge-triggered D-type flip-flops with synchronous clocking on the positive-going CP edge. All state transitions-including preset, count, and reset-occur synchronously relative to CP, eliminating race conditions during terminal count rollover or parallel load.
Its look-ahead carry architecture enables seamless n-bit cascading: CET feeds forward to enable TC output, which pulses HIGH for one CP cycle when Q0–Q3 = 1111 and CET = HIGH; CEP must also be HIGH for counting to proceed. MR asserts synchronously on the next CP edge, forcing Q0–Q3 = 0000 regardless of PE/CEP/CET states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | 4-bit synchronous binary counter with parallel load and synchronous reset |
| Supply Voltage Range | 2.0 V to 6.0 V - supports 3.3 V and 5 V logic domains without level shifting |
| Max Clock Frequency | 55 MHz at VCC = 6.0 V - enables high-speed timing in engine ECU pulse-width modulation |
| Propagation Delay (CP to Qn) | 16 ns typical at VCC = 6.0 V - ensures tight timing margins in multi-stage counters |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive use |
| Input Logic Level | CMOS-compatible - VIH = 4.2 V, VIL = 1.8 V at VCC = 6.0 V; no TTL interface required |
| Terminal Count Pulse Width | ≈ duration of Q0 HIGH - provides clean, jitter-free enable signal for next cascade stage |
Pinout & Package
74HC163D-Q100 is housed in a 16-lead SO16 plastic small outline package (SOT109-1), 3.9 mm body width, with standard gull-wing leads and JEDEC-compliant footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MR (Pin 1) | Synchronous master reset | Active-LOW; forces Q0–Q3 = 0000 on next CP rising edge - enables precise zero-synchronization across multiple counters |
| CP (Pin 2) | Clock input | Positive-edge triggered; all flip-flops update simultaneously - eliminates ripple delay and metastability in state transitions |
| D0–D3 (Pins 3–6) | Data inputs | Parallel load values transferred to Q0–Q3 when PE = LOW and CP rises - supports dynamic modulus reconfiguration |
| CEP (Pin 7) | Count enable (parallel) | Must be HIGH with CET for counting; enables local gating of count action without affecting TC propagation |
| GND (Pin 8) | Ground reference | 0 V return path for all internal logic and I/O - decoupling critical for noise immunity in automotive harness environments |
| PE (Pin 9) | Parallel enable | Active-LOW; enables synchronous loading of D0–D3 independent of CEP/CET state - allows preset during active counting |
| CET (Pin 10) | Count enable carry | Enables TC output when HIGH and counter reaches 15; feeds forward to next stage - simplifies modular counter expansion |
| Q0–Q3 (Pins 14,13,12,11) | Flip-flop outputs | Binary-weighted outputs (LSB→MSB); Q0 toggles every CP, Q3 toggles every 16th CP - used for timing division and event sequencing |
| TC (Pin 15) | Terminal count output | HIGH for one CP cycle when Q0–Q3 = 1111 and CET = HIGH - drives enable input of cascaded counter or interrupt generator |
| VCC (Pin 16) | Supply voltage | 2.0–6.0 V power rail; internal clamp diodes allow safe interfacing to overvoltage signals via current-limiting resistors |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous reset (MR) | Eliminates output glitches during reset; enables deterministic zero alignment across multiple counters without external combinational logic |
| Look-ahead carry (CET → TC) | Reduces inter-stage propagation delay in multi-counter chains - supports >100 MHz effective system clock rates in cascaded configurations |
| Two independent count enables (CEP & CET) | Allows hierarchical gating: CEP controls local counting; CET controls carry propagation - essential for programmable modulus and hierarchical timing trees |
| Clamp diodes on all inputs | Permits direct connection to signals exceeding VCC (e.g., 12 V sensor lines) using series current-limiting resistors - reduces BOM count in automotive sensor interfaces |
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from −40 °C to +125 °C - meets thermal stress requirements for engine control units and transmission controllers |

FAQ
What is the maximum clock frequency supported by 74HC163D-Q100 at 5.0 V?
At VCC = 5.0 V and CL = 15 pF, the 74HC163D-Q100 achieves a maximum clock frequency of 51 MHz. This value is measured under recommended operating conditions and reflects the device's propagation delay (tpd = 17 ns typical) and setup/hold timing margins. Operation above this frequency risks timing violations in cascaded configurations.
How does the synchronous reset differ from asynchronous reset in practical circuit design?
The synchronous reset (MR) only takes effect on the next positive CP edge, ensuring all outputs change state simultaneously and avoiding metastability or partial-state glitches. Unlike asynchronous resets, it requires no additional debouncing or pulse-stretching circuitry and integrates cleanly into clock-domain-crossing designs in automotive ECUs.
Can 74HC163D-Q100 be used to build a modulo-10 counter without external gates?
No - the 74HC163D-Q100 requires one external NAND gate to decode Q3 and Q1 (1010₂ = 10) and feed the result to MR for synchronous reset. Its inherent modulo-16 behavior mandates minimal external logic for non-power-of-two moduli, but the synchronous reset ensures glitch-free rollover unlike ripple-counter alternatives.
Is the TC output pulse width affected by supply voltage or temperature?
Yes - TC pulse width tracks Q0 HIGH time, which varies with VCC and temperature. At VCC = 6.0 V and 25 °C, TC pulse width is approximately equal to Q0 HIGH time (≈50% duty cycle). Over temperature (−40 °C to +125 °C), pulse width variation remains within ±15% due to matched internal delays, preserving reliable cascading performance.
