Product details

Overview

74HC393PW,118 from Nexperia is a dual 4-bit binary ripple counter IC with two independent asynchronous master reset inputs (1MR, 2MR), two edge-triggered clock inputs (1CP, 2CP), and eight buffered outputs (1Q0–1Q3, 2Q0–2Q3). It operates from 2.0 V to 6.0 V, advances on HIGH-to-LOW clock transitions, and clears all outputs to LOW when MR is HIGH. It is used in digital timing, frequency division, and event counting circuits requiring low-power CMOS logic.

For engineers reviewing the 74HC393PW,118 datasheet, 74HC393PW,118 pinout, 74HC393PW,118 application, or 74HC393PW,118 equivalent, this device supports dual independent divide-by-2ⁿ (n ≤ 4) functions per counter, offers TTL-compatible input levels only in the 74HCT variant, and requires attention to propagation delay stacking in ripple configurations.

Technical Context

This device implements two cascaded T-type flip-flop stages per counter, forming asynchronous (ripple) binary counters where each stage triggers the next on its output transition. Clocking is edge-sensitive (HIGH-to-LOW), and reset is fully asynchronous and active-HIGH - asserting either MR immediately forces its associated Q0–Q3 outputs LOW regardless of clock state.

Input clamping diodes enable safe interfacing to voltages exceeding VCC when current-limiting resistors are used. The TSSOP14 package (SOT402-1) supports surface-mount assembly with 0.65 mm lead pitch, 4.4 mm body width, and thermal performance derated at 7.3 mW/K above 81 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage range	2.0 V to 6.0 V - supports mixed-voltage system interfacing and battery-powered operation down to 2 V.
Max clock frequency (VCC = 6.0 V)	107 MHz - defines upper limit for first-stage (Q0) toggling; subsequent stages exhibit cumulative delay.
Propagation delay (1CP → 1Q0, VCC = 4.5 V)	15 ns typical - determines minimum clock period before first output stabilizes; critical for setup/hold timing.
Output drive (VOH @ IO = −4.0 mA, VCC = 4.5 V)	3.98 V min - ensures robust HIGH-level logic margin into standard CMOS loads.
Input leakage current (VI = VCC or GND)	±0.1 μA max at 25 °C - enables high-impedance control lines without significant DC loading.
Power dissipation capacitance (CPD)	23 pF - used to calculate dynamic power: PD = CPD × VCC² × f_i × N + Σ(C_L × VCC² × f_o).
Operating temperature range	−40 °C to +125 °C - qualified for industrial and extended-temperature embedded applications.

Pinout & Package

TSSOP14 package (SOT402-1): plastic thin shrink small outline, 14 leads, 0.65 mm pitch, 4.4 mm body width, 1.2 mm max height.

Pin/Terminal	Circuit Role	Design Meaning
1	1CP	First counter clock input - HIGH-to-LOW edge triggers 1Q0 toggle; asynchronous to other signals.
2	VCC	Positive supply rail - must be decoupled locally; no internal regulation or brown-out detection.
3	1MR	First counter master reset - active-HIGH; forces 1Q0–1Q3 LOW independently of 1CP state.
4	2CP	Second counter clock input - functionally identical to 1CP but electrically isolated.
5	1Q0	LSB output of first counter - toggles at half the 1CP frequency; drives subsequent stage or external load.
6	2MR	Second counter master reset - active-HIGH; independent control avoids cross-counter interference.
7	1Q1	Second-bit output of first counter - toggles at quarter the 1CP frequency; subject to ripple delay from 1Q0.
8	2Q0	LSB output of second counter - provides parallel frequency division path with no shared reset or clock.
9	1Q2	Third-bit output of first counter - divides 1CP by 8; delay accumulates across three internal stages.
10	2Q1	Second-bit output of second counter - enables independent 4-bit division ratio selection per channel.
11	1Q3	MSB output of first counter - toggles every 16th 1CP edge; final stage in 4-bit chain.
12	2Q2	Third-bit output of second counter - supports modulo-16 counting without external feedback logic.
13	2CP	Redundant reference - pin 4 already assigned to 2CP; confirms functional duplication in pin mapping.
14	VCC	Redundant reference - pin 2 already assigned to VCC; reflects dual-supply pad design in TSSOP layout.
7	GND	Ground reference - single ground pin serves both counters; requires low-inductance PCB return path.
8–11	2Q3, 2Q2, 2Q1, 2Q0	Outputs mapped in reverse order - 2Q3 is pin 8, 2Q2 is pin 9, etc., per Fig. 7 pin configuration.

Key Features

Feature	Design Value
Dual independent 4-bit ripple counters	Enables two separate divide-by-2, -4, -8, or -16 functions in one package - reduces board space vs. discrete 74HC74 + gates.
Asynchronous active-HIGH master reset	Allows immediate, clock-independent clearing of each counter - essential for deterministic initialization in state machines.
CMOS input levels (74HC variant)	VIH ≥ 3.15 V @ VCC = 4.5 V ensures compatibility with 3.3 V microcontroller GPIOs without level shifters.
Clamp diode-equipped inputs	Permits safe interface to voltages > VCC using series resistors - eliminates need for external protection diodes.
ESD robustness (HBM > 2000 V)	Reduces handling sensitivity during SMT assembly and field service - lowers risk of latent damage in production.

Applications

Frequency Division

Digital Timing Generator

Use Scenario: Generating sub-harmonics of a master clock for peripheral synchronization in microcontroller-based systems.

IC Role / Device Role / Timing Role: Each counter acts as a synchronous divider chain - 1CP receives system clock; 1Q0–1Q3 provide /2, /4, /8, /16 clocks.

Use Value: Eliminates need for programmable timers or external PLLs for fixed-ratio clock scaling, reducing firmware overhead and BOM count.

Use Scenario: Creating precise time delays for LED blink patterns, relay actuation, or sensor sampling intervals.

IC Role / Device Role / Timing Role: Counter output drives a comparator or logic gate that triggers an event after N clock cycles.

Use Value: Provides stable, jitter-free delays up to 65,535 cycles (two cascaded 4-bit counters) without software intervention.

Event Counting Interface

Industrial Control Sequencing

Use Scenario: Capturing pulse counts from rotary encoders, flow meters, or mechanical switches in factory automation.

IC Role / Device Role / Timing Role: 1CP accepts conditioned encoder A/B pulses; 1Q0–1Q3 feed latch or microcontroller input port.

Use Value: Hardware-based counting offloads CPU, prevents missed edges at high rates (≤107 MHz), and maintains count during MCU sleep.

Use Scenario: Implementing step-and-direction sequencing for stepper motor drivers or pneumatic valve banks.

IC Role / Device Role / Timing Role: Outputs sequence through predefined states (e.g., Q0→Q1→Q2→Q3) to activate driver enable lines in order.

Use Value: Delivers deterministic, glitch-free state progression without FPGA or complex CPLD logic - ideal for safety-critical sequencing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual binary counter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74HCT393PW,118	Same pinout and function, but TTL-compatible inputs (VIH = 2.0 V min @ VCC = 4.5 V) instead of CMOS.	Better interoperability with legacy 5 V TTL logic families; higher input current draw than HC variant.	Select when interfacing directly to 74LS or older microcontrollers with weak pull-ups.
SN74LV393APWR	Lower VCC range (1.65–5.5 V), 32 mA output drive, and 10 ns t_pd @ 3.3 V - optimized for 3.3 V systems.	Superior noise immunity and speed at 3.3 V; not rated for 6 V operation like 74HC393.	Prefer for modern low-voltage designs where 6 V tolerance is unnecessary and faster settling is required.

Compared with 74HCT393PW,118, the 74HC393PW,118 offers lower static power and wider supply flexibility but requires stronger drive for VIH; versus SN74LV393APWR, it trades 3.3 V optimization for 6 V headroom and broader legacy compatibility.

FAQ

Can the two counters be cascaded for an 8-bit ripple counter?

Yes - connect 1Q3 to 2CP to form an 8-bit chain. However, total propagation delay accumulates across all stages (e.g., ~12 ns × 8 = 96 ns worst-case at 6 V), limiting maximum usable clock frequency well below the 107 MHz single-stage spec. Synchronous counters like 74HC163 are preferred for high-speed 8-bit counting.

What is the impact of ripple delay on timing accuracy?

Ripple delay causes output transitions to occur sequentially rather than simultaneously: 1Q0 changes first, then 1Q1 after ~5 ns (VCC = 4.5 V), then 1Q2, etc. This creates skew between bits - critical in applications like address generation or synchronous sampling where multi-bit alignment matters. Use synchronous counters if bit-aligned edges are required.

Is the TSSOP14 package RoHS-compliant and lead-free?

Yes - the 74HC393PW,118 uses a lead-free, halogen-free, RoHS-compliant TSSOP14 package (SOT402-1) with matte tin terminal finish. It meets JEDEC J-STD-020 moisture sensitivity level 1 (unlimited floor life at ≤30 °C/60% RH) and qualifies for reflow per IPC/JEDEC J-STD-020.

How does input clamping affect interfacing with 12 V sensors?

Clamping diodes allow safe connection to 12 V sources when a series current-limiting resistor (e.g., 10 kΩ) is used: diode conduction limits input voltage to ~VCC + 0.7 V. Without the resistor, excessive current (>20 mA) can damage the input structure. Always verify resistor value using IIK max (±20 mA) and worst-case V_IN.
