Product details

Overview

74HCT163D,653 from Nexperia is a TTL-level-compatible, synchronous 4-bit binary counter with parallel load, synchronous reset, and look-ahead carry-designed for precise modulus-N counting in digital control logic. It operates from 4.5 V to 5.5 V, delivers glitch-free outputs via edge-triggered clock (CP), and supports cascading via CEP/CET/TC signals. Used in industrial timer modules, programmable logic controllers, and address sequencing circuits.

For engineers reviewing the 74HCT163D,653 datasheet, 74HCT163D,653 pinout, 74HCT163D,653 application, or 74HCT163D,653 equivalent, this device offers deterministic timing (t_pd = 23–49 ns @ V_CC = 4.5 V), robust noise immunity (V_IL = 0.8 V, V_IH = 2.0 V), and seamless integration into 5 V TTL-compatible systems requiring synchronous presettable counting.

Technical Context

This device implements four edge-triggered D-type flip-flops with synchronous parallel load and reset, enabling deterministic state transitions on every rising CP edge. Its dual count-enable inputs (CEP and CET) gate counting and feed forward to TC, while internal look-ahead carry ensures predictable propagation across cascaded stages.

The synchronous MR input forces Q0–Q3 to LOW on the next CP edge regardless of PE, CEP, or CET states-enabling clean modulus reconfiguration with minimal external logic. Input clamp diodes allow safe interfacing to voltages exceeding V_CC, and ESD protection exceeds 2 kV HBM.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Family	74HCT - TTL-compatible input thresholds (V_IH = 2.0 V, V_IL = 0.8 V @ V_CC = 5 V)
Count Width	4-bit binary (Q0–Q3); terminal count (TC) asserts at 1111 → 0000 transition
Propagation Delay	t_pd(CP→Qn) = 23 ns typ, 49 ns max @ V_CC = 4.5 V, CL = 50 pF - sets max cascade clock rate
Supply Range	V_CC = 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL bus systems
Operating Temp	-40 °C to +125 °C - qualified for automotive under-hood and industrial control environments
Package	SO16 (SOT109-1), 3.9 mm body width - surface-mount compatible with IPC-7351B footprint

Pinout & Package

74HCT163D,653 is housed in a plastic small outline package (SO16, SOT109-1) with 16 leads, 3.9 mm body width, and standard JEDEC MS-012 outline. Pin 1 is marked by a bevelled corner or dot; pin numbering follows counter-clockwise convention from top-left.

Pin/Terminal	Circuit Role	Design Meaning
1 MR	Synchronous master reset	Active-LOW; forces Q0–Q3 = 0000 on next CP rising edge - enables clean modulus reconfiguration
2 CP	Clock input	Rising-edge triggered; all flip-flops update simultaneously - eliminates ripple delay and output glitches
3–6 D0–D3	Parallel data inputs	Loaded into Q0–Q3 when PE = LOW on CP edge - supports presetting any 4-bit value
7 CEP	Count enable parallel	Enables counting only when HIGH; used with CET to gate TC and enable cascaded stage
8 GND	Ground reference	0 V return path for all internal logic and I/O - must be low-impedance for stable timing
9 PE	Parallel enable	Active-LOW; enables parallel load regardless of CEP/CET state - decouples loading from count enable
10 CET	Count enable carry	Feeds forward to TC; TC goes HIGH only when CET = HIGH and counter = 1111 - synchronizes multi-stage carry
11–14 Q3–Q0	Flip-flop outputs	Q0 LSB, Q3 MSB; outputs reflect current count state - used for feedback, decode, or display driving
15 TC	Terminal count output	HIGH pulse ≈ duration of Q0 HIGH - directly enables next cascaded counter's CEP/CET without external logic
16 V_CC	Supply voltage	+4.5 V to +5.5 V; powers all logic - requires local 100 nF ceramic decoupling near pin 16

Key Features

Feature	Design Value
Synchronous reset (MR)	Eliminates race conditions during modulus reconfiguration - no external debounce or gating required
Look-ahead carry (TC)	Reduces inter-stage propagation delay in multi-counter chains - enables higher overall system clock rates
TTL-compatible inputs	Accepts standard 5 V TTL logic levels (V_IH ≥ 2.0 V, V_IL ≤ 0.8 V) without level-shifting circuitry
Clamp diode inputs	Permits safe interface to signals up to V_CC + 0.5 V using series current-limiting resistors
ESD robustness	HBM > 2000 V, MM > 200 V - enhances reliability in automated PCB assembly and field-deployed equipment

Applications

Industrial Timer Modules

Programmable Logic Controllers (PLCs)

Use Scenario: Generating precise time bases for motor run-time control, conveyor belt cycle timing, and batch process sequencing.

IC Role / Device Role / Timing Role: Primary 4-bit counter stage in cascaded modulo-N timers; MR and PE configure start values per recipe step.

Use Value: Synchronous reset ensures zero-jitter restart after fault recovery; TC output directly clocks next counter stage for deterministic multi-second intervals.

Use Scenario: Address sequencing in I/O expansion modules where discrete sensor/actuator addresses are scanned in fixed order.

IC Role / Device Role / Timing Role: Address pointer generator - Q0–Q3 drives 4-bit address bus; CEP/CET enable/disable scanning based on module enable status.

Use Value: Parallel load (PE) allows dynamic address offset programming via PLC firmware; TTL compatibility simplifies integration with legacy 5 V backplane logic.

Digital Panel Meters

Test Equipment Counters

Use Scenario: Driving 7-segment decoder inputs in benchtop multimeters and power analyzers requiring stable digit update timing.

IC Role / Device Role / Timing Role: BCD-compatible counter feeding multiplexed display driver; TC triggers digit increment and overflow flag.

Use Value: Glitch-free outputs prevent phantom digit flicker; -40 °C to +125 °C rating ensures operation inside sealed instrument enclosures.

Use Scenario: Event counting in frequency counters and logic analyzers where input pulses must be tallied with minimal latency.

IC Role / Device Role / Timing Role: First-stage prescaler - CP accepts conditioned input pulses; TC feeds higher-order counters for 16-bit+ resolution.

Use Value: 26 MHz max clock rate (@ V_CC = 4.5 V) supports high-frequency measurement; synchronous load enables gated-count capture on trigger event.

Equivalent & Alternatives

The following parts are listed as comparable options for similar synchronous 4-bit binary counter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74HC163D,653	CMOS input thresholds (V_IH = 3.15 V min @ V_CC = 4.5 V); wider V_CC range (2.0–6.0 V)	Better suited for mixed-voltage systems (e.g., 3.3 V control + 5 V peripherals) but requires level translation when interfacing to TTL	Select when operating below 4.5 V or integrating with HC-family logic; verify VIH/VIL margins with driver outputs
SN74LS163N	Bipolar TTL technology; higher ICC (20 mA typical), slower t_pd (25–40 ns), narrower temp range (-40 °C to +85 °C)	Legacy board replacement only; incompatible with modern low-power designs due to higher static current and thermal limits	Use only for direct LS-family drop-in replacement; avoid in new designs due to obsolete process and supply constraints

Compared with 74HC163D,653 and SN74LS163N, the 74HCT163D,653 uniquely balances TTL-level interoperability, low power (ICC < 160 μA), and extended temperature support - making it optimal for new 5 V industrial control designs requiring long-term supply stability.

FAQ

Can 74HCT163D,653 operate at 3.3 V?

No - the 74HCT163D,653 is specified only for V_CC = 4.5 V to 5.5 V. At 3.3 V, input thresholds (V_IH = 2.0 V) remain valid, but VOH drops below TTL HIGH minimum (3.0 V), risking downstream logic misreads. Use 74HC163D,653 for 3.3 V systems.

What is the minimum pulse width required on CP?

The minimum CP HIGH and LOW pulse width is 20 ns each at V_CC = 4.5 V (Table 7). This corresponds to a maximum guaranteed clock frequency of 26 MHz under standard test conditions (CL = 50 pF), though layout-dependent signal integrity may require margin.

How does TC behave during parallel load?

TC remains LOW during parallel load (PE = LOW), even if D0–D3 = 1111. TC only asserts HIGH when CET = HIGH and the counter reaches 1111 *during counting* - ensuring TC reflects actual count progression, not loaded state.

Is MR asynchronous or synchronous?

MR is synchronous: it is sampled on the rising edge of CP and clears Q0–Q3 to 0000 on the *next* CP edge. This avoids metastability and ensures deterministic timing - unlike asynchronous resets, MR cannot cause race conditions in pipelined logic.
