Product details
Overview
74HC160DB,118 from Nexperia is a synchronous presettable BCD decade counter IC with asynchronous master reset (MR), internal look-ahead carry, and dual count-enable inputs (CEP/CET) for cascading. It operates on positive-edge clock (CP), supports parallel data loading via D0–D3 and PE, and delivers terminal count (TC) pulse synchronized to Q0. Used in digital timing, frequency division, and control logic where precise decade sequencing is required.
For engineers reviewing the 74HC160DB,118 datasheet, 74HC160DB,118 pinout, 74HC160DB,118 application, or 74HC160DB,118 equivalent, this page provides verified functional identity, SO16 pin mapping, BCD counting behavior, TC timing characteristics, and validated alternatives for industrial control and instrumentation designs.
Technical Context
The 74HC160DB,118 implements four edge-triggered D-type flip-flops with synchronous load and asynchronous clear. Its decade counter advances only when both CEP and CET are HIGH, and TC asserts HIGH for one CP cycle at state 9 (Q3Q2Q1Q0 = 1001), enabling direct cascade of multiple stages without external gating.
Input clamping diodes allow interfacing with voltages exceeding VCC using current-limiting resistors. The device complies with JEDEC 7A, supports CMOS input thresholds, and guarantees operation from -40 °C to +125 °C with supply voltage ranging 2.0 V to 6.0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Synchronous BCD decade counter with parallel load and asynchronous reset |
| Supply Voltage (VCC) | 2.0 V to 6.0 V - enables compatibility with 3.3 V and 5 V logic systems |
| Max Clock Frequency | 66 MHz at VCC = 6.0 V - determines maximum counting rate in high-speed timing chains |
| Propagation Delay (CP to Qn) | 18 ns typical at VCC = 6.0 V - defines minimum clock period for reliable state transition |
| Terminal Count Pulse Width | ≈ duration of Q0 HIGH - provides self-timed enable signal for next-stage counter |
| Operating Temperature | -40 °C to +125 °C - qualified for extended industrial and automotive-adjacent environments |
| ESD Protection | HBM > 2000 V, MM > 200 V - ensures robustness during board handling and assembly |
Pinout & Package
74HC160DB,118 is housed in a plastic small outline package (SO16, SOT109-1) with 16 leads, 3.9 mm body width, and standard 1.27 mm pitch. Pin 1 is MR (asynchronous reset); pin 16 is VCC; pin 8 is GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (MR) | Asynchronous master reset | Forces Q0–Q3 LOW immediately, independent of clock or enable states |
| 2 (CP) | Clock input | Positive-edge triggered - all flip-flops update simultaneously on rising edge |
| 3–6 (D0–D3) | Data inputs | Parallel load values transferred to Q0–Q3 when PE is LOW and CP rises |
| 7 (CEP) | Count enable parallel | Enables counting only when HIGH; used with CET for n-bit cascading control |
| 8 (GND) | Ground reference | 0 V return path for all internal logic and output drivers |
| 9 (PE) | Parallel enable | Active-LOW - enables synchronous loading of D0–D3 regardless of CEP/CET |
| 10 (CET) | Count enable carry | Enables TC output when HIGH and counter reaches terminal state (9) |
| 11–14 (Q3–Q0) | BCD outputs | Q0 LSB, Q3 MSB - represent decimal 0–9 as 4-bit binary-coded decimal |
| 15 (TC) | Terminal count output | HIGH for one CP cycle at state 9 - used to cascade to next counter stage |
| 16 (VCC) | Supply voltage | Power rail for CMOS logic core; must be decoupled near package |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous presettable counting | Enables deterministic initialization to any BCD value (0–9) on next clock edge |
| Look-ahead carry architecture | Eliminates ripple delay in multi-stage counters by generating TC early in cycle |
| Dual count-enable inputs (CEP/CET) | Allows hierarchical enable control - CEP gates counting, CET gates TC assertion |
| Asynchronous master reset (MR) | Guarantees immediate zero-state recovery without waiting for clock or enable conditions |
| Clamped inputs with ESD protection | Permits safe interfacing to overvoltage sources using series resistors; meets HBM >2 kV |

Equivalent & Alternatives
The following parts are listed as comparable options for similar BCD decade counter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT160D,653 | TTL-compatible input thresholds (VIH = 2.0 V min), otherwise identical function and pinout | Required when interfacing with legacy 5 V TTL logic families without level shifters | Select when system uses mixed 74HCT/74HC logic; not suitable for 3.3 V-only designs |
| SN74LS160N | Bipolar TTL technology; higher power (30 mW avg), slower speed (max 35 MHz), 5 V-only supply | Legacy replacement in through-hole boards where PCB layout prohibits SO16 footprint | Choose only for backward compatibility; avoid in new designs due to power and thermal limitations |
Compared with 74HC160DB,118, the 74HCT160D,653 offers seamless integration into mixed-signal 5 V systems but lacks 3.3 V compatibility, while SN74LS160N trades speed and efficiency for legacy footprint support-neither matches the wide-voltage, low-power, and SO16-optimized profile of the original.

FAQ
What is the difference between MR and PE functions?
MR (pin 1) is an asynchronous master reset that forces Q0–Q3 LOW immediately, regardless of clock or enable states. PE (pin 9) is a synchronous parallel enable: when LOW, it loads D0–D3 into Q0–Q3 on the next rising CP edge, even if CEP/CET are LOW. MR overrides all logic; PE requires clock synchronization.
Can 74HC160DB,118 operate at 3.3 V supply?
Yes - the 74HC160DB,118 is fully specified from 2.0 V to 6.0 V. At 3.3 V, VIH is 2.1 V min and VIL is 1.35 V max, ensuring compatibility with standard 3.3 V CMOS logic families. Propagation delay increases to ~37 ns (CP to Qn), and fmax drops to ~55 MHz, both within typical system margins.
How is terminal count (TC) generated and used?
TC (pin 15) goes HIGH for one CP cycle when the counter reaches state 9 (Q3Q2Q1Q0 = 1001) and CET is HIGH. Its pulse width approximates that of Q0, making it ideal for directly enabling the CP input of the next cascaded 74HC160DB,118. TC does not require external logic for multi-decade counting.
Is 74HC160DB,118 RoHS compliant and halogen-free?
Yes - the 74HC160DB,118 (SOT109-1 package) is RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. Nexperia confirms compliance in its official product change notices and material declarations, with lead-free solderability verified to J-STD-020 standards.
