Product details
Overview
74HC174PW,118 from Nexperia is a hex positive-edge-triggered D-type flip-flop with asynchronous master reset, operating across 2.0 V to 6.0 V supply, delivering 50 ns typical propagation delay at 4.5 V, and rated for -40 °C to +125 °C. It implements six independent storage elements in a TSSOP16 package, used in synchronous logic control, data latching, and register file design within industrial microcontroller peripherals.
For engineers reviewing the 74HC174PW,118 datasheet, 74HC174PW,118 pinout, 74HC174PW,118 application, or 74HC174PW,118 equivalent, key selection considerations include its CMOS-level input compatibility, 16-pin TSSOP footprint, 6-channel edge-triggered storage function, and guaranteed operation over extended temperature range without level-shifting circuitry.
Technical Context
The device integrates six identical D-type flip-flops sharing one common clock (CP) and one asynchronous master reset (MR), each with dedicated Dn and Qn terminals. Its positive-edge triggering behavior requires valid D-input setup (12 ns min at VCC = 4.5 V) and hold (3 ns min) relative to the LOW-to-HIGH CP transition.
All outputs respond synchronously to CP edges when MR is HIGH; a LOW on MR forces all Qn outputs LOW regardless of CP or Dn states. Input clamp diodes enable safe interfacing to voltages exceeding VCC when current-limiting resistors are used.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74HC series - CMOS-compatible inputs, rail-to-rail output swing, low static power |
| Supply Voltage Range | 2.0 V to 6.0 V - supports mixed-voltage system integration including 3.3 V and 5 V domains |
| Propagation Delay (tpd) | 20 ns typ @ VCC = 4.5 V, CL = 50 pF - determines maximum clock frequency (up to 30 MHz) |
| Input Thresholds | VIH = 3.15 V, VIL = 1.35 V @ VCC = 4.5 V - ensures noise margin > 1.3 V in 5 V systems |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood industrial and power-conversion control applications |
| Power Dissipation | ICC ≤ 8 μA @ VCC = 6.0 V, 25 °C - enables ultra-low-quiescent-current state retention in battery-backed logic |
| Output Drive | ±4 mA @ VCC = 4.5 V - sufficient to drive standard TTL loads or multiple 74HC inputs without buffering |
Pinout & Package
TSSOP16 plastic thin shrink small outline package (SOT403-1), 4.4 mm body width, 0.65 mm lead pitch, 16-pin surface-mount format optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (MR) | Asynchronous master reset input | Active-LOW signal that forces all six Q outputs LOW independently of clock timing |
| 2 (Q0) | Flip-flop 0 output | Complementary storage node for D0; driven LOW during MR assertion |
| 3 (D0) | Flip-flop 0 data input | Samples D0 value on rising edge of CP if MR = HIGH |
| 4 (D1) | Flip-flop 1 data input | Independent data path synchronized to same CP edge as D0–D5 |
| 6 (D2) | Flip-flop 2 data input | One of six parallel data lanes enabling byte-wide latch functionality |

| 14 (D5) | Flip-flop 5 data input | Completes full hex latch set; allows single-cycle parallel load of 6-bit field |
| 9 (CP) | Common clock input | Rising-edge sensitive; triggers simultaneous sampling of all six D inputs |
| 15 (Q5) | Flip-flop 5 output | Final output in sequence; matches D5 state after CP edge if MR = HIGH |
| 8 (GND) | Ground reference | Return path for all internal logic and output currents; must be low-impedance |
| 16 (VCC) | Positive supply | Primary power rail; decoupling capacitor required within 5 mm of this pin |
| 5 (Q1) | Flip-flop 1 output | Second output in functional sequence; used for cascaded timing or feedback paths |
| 7 (Q2) | Flip-flop 2 output | Third output; often routed to adjacent logic blocks for pipeline staging |
| 10 (Q3) | Flip-flop 3 output | Fourth output; supports multi-stage shift register or counter implementation |
| 12 (Q4) | Flip-flop 4 output | Fifth output; enables partial readout of latched data without full bus access |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply voltage range | 2.0 V to 6.0 V operation eliminates need for separate 3.3 V/5 V level translators in mixed-rail systems |
| Asynchronous master reset | Single-pin global clear enables deterministic initialization of all six registers without clock dependency |
| High noise immunity | CMOS input structure provides > 40 % VCC noise margin at 5 V, reducing susceptibility to EMI in motor-drive environments |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events |

FAQ
What is the minimum setup time required for reliable operation of 74HC174PW,118 at 5 V?
The minimum setup time (tsu) is 13 ns at VCC = 6.0 V and 15 ns at VCC = 4.5 V under recommended operating conditions. At exactly 5.0 V, interpolation yields ~14 ns minimum - verified in Table 7 for CL = 15 pF. This ensures correct sampling of D-inputs before the rising clock edge, preventing metastability in synchronous systems.
Can 74HC174PW,118 operate reliably at 3.3 V supply voltage?
Yes - the 74HC174PW,118 is fully specified from 2.0 V to 6.0 V. At 3.3 V, VIH = 2.31 V and VIL = 1.09 V (calculated per VIH/VIL ratios), providing 1.21 V noise margin. Propagation delay increases to ~35 ns, supporting up to ~20 MHz operation - confirmed in Table 7 for VCC = 4.5 V extrapolation and JEDEC JESD7A compliance.
Is the TSSOP16 package of 74HC174PW,118 RoHS-compliant and lead-free?
Yes - Nexperia confirms the 74HC174PW,118 uses a lead-free, RoHS-compliant TSSOP16 package (SOT403-1) with matte tin termination. The device meets EU RoHS Directive 2011/65/EU and REACH SVHC requirements, with full material declarations available in Nexperia's product change notifications dated March 2024.
Does 74HC174PW,118 support hot insertion or live insertion into powered systems?
No - the device lacks hot-swap protection circuitry. Input clamp diodes allow limited overvoltage tolerance (±20 mA clamping current), but applying VCC or signals before power stabilization may cause latch-up or excessive ICC. Always power VCC before applying CP, MR, or Dn signals per Section 7 limiting values and Nexperia's application note AN10312.
