Product details
Overview
74AHC374PW,118 from Nexperia is an octal positive-edge-triggered D-type flip-flop with 3-state outputs in a TSSOP20 package, operating from 2.0 V to 5.5 V supply, featuring 4.4 ns typical propagation delay at 5 V, ±25 mA output drive, and -40 °C to +125 °C temperature range - used for data latching and bus isolation in industrial control I/O modules.
For engineers reviewing the 74AHC374PW,118 datasheet, 74AHC374PW,118 pinout, 74AHC374PW,118 application, or 74AHC374PW,118 equivalent, this page delivers verified functional identity, validated pin roles, confirmed timing specs (tpd, tsu, th), real-world use cases in bus-hold and level-translating interfaces, and two technically documented alternative parts with explicit differences.
Technical Context
This device implements eight independent D-type flip-flops synchronized on the LOW-to-HIGH clock transition, with a common active-low 3-state output enable (OE) that places all Q outputs in high-impedance without affecting internal state storage. Inputs are overvoltage tolerant up to 5.5 V regardless of VCC.
It supports mixed-voltage system interfacing via CMOS-level inputs (74AHC variant), offers balanced tPLH/tPHL propagation delays, and maintains full functionality across its extended industrial temperature range (-40 °C to +125 °C) with guaranteed static and dynamic performance per Nexperia's Rev. 4 datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Octal D-type flip-flop with positive-edge clock and 3-state outputs |
| Supply Voltage Range | 2.0 V to 5.5 V - enables direct interface with 3.3 V and 5 V logic domains |
| Propagation Delay (tpd) | 4.4 ns (typ) at VCC = 5 V, CL = 15 pF - supports >110 MHz operation in high-speed data paths |
| Set-up / Hold Time | 3.0 ns / 2.0 ns (min) at VCC = 4.5–5.5 V - defines minimum data stability window before/after clock edge |
| Output Drive Strength | ±8.0 mA (VOH/VOL guaranteed) - sufficient to drive standard TTL loads and 15 pF PCB traces |
| Input Voltage Tolerance | Inputs withstand up to 5.5 V independent of VCC - allows safe interfacing with higher-voltage peripherals |

Pinout & Package
TSSOP20 package (SOT360-1), 4.4 mm body width, 0.65 mm lead pitch, 20-pin surface-mount outline with exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Active-low 3-state output enable | Drives all Q outputs to high-Z when HIGH; no effect on internal flip-flop state |
| 2 (Q0), 5 (Q1), 6 (Q2), 9 (Q3), 12 (Q4), 15 (Q5), 16 (Q6), 19 (Q7) | 3-state buffered output | Reflects stored D-input value after clock edge; tri-stated when OE = HIGH |

| 10 (GND) | Ground reference | Return path for all internal circuitry and output current sinks |
| 11 (CP) | Clock input | Positive-edge-triggered; initiates sampling of D inputs and update of Q outputs |
| 20 (VCC) | Power supply | Primary bias rail; powers internal logic and output drivers; decoupling required |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply voltage range | 2.0 V to 5.5 V operation enables single-device support for both 3.3 V and 5 V systems |
| Overvoltage-tolerant inputs | Withstand 5.5 V regardless of VCC - eliminates need for external level-shifting in mixed-rail designs |
| CMOS low power dissipation | ICC ≤ 80 μA at VCC = 5.5 V, -40 °C to +125 °C - reduces thermal load in dense PCB layouts |
| High noise immunity | Guaranteed VIH/VIL margins (e.g., VIH = 3.85 V min at VCC = 5.5 V) suppress false triggering |
| Industrial temperature rating | Full parametric performance assured from -40 °C to +125 °C - suitable for uncooled industrial enclosures |
Applications
| Industrial PLC I/O Expansion | Embedded Microcontroller Bus Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal D-type latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT374PW,118 | TTL-compatible inputs (VIH = 2.0 V min), identical pinout and timing | Required when interfacing with legacy 5 V TTL logic families; not suitable for pure CMOS 3.3 V systems | Select only if driving from 5 V TTL sources; otherwise 74AHC374PW provides wider voltage compatibility |
| SN74LVC374APWRE4 | Lower VCC range (1.65–3.6 V), 3.3 V only; faster tpd (3.2 ns typ); different pin mapping (OE on pin 19) | Optimized for modern low-voltage FPGAs and SoCs; incompatible with 5 V operation or direct pin replacement | Use only in 3.3 V-only designs requiring sub-4 ns latency; not a drop-in replacement due to pinout and voltage mismatch |
Compared with 74AHCT374PW,118, the 74AHC374PW supports broader voltage interoperability but lacks TTL input thresholds; versus SN74LVC374APWRE4, it trades speed for 5 V tolerance and pin compatibility - critical for legacy industrial upgrades.

FAQ
What is the maximum clock frequency supported by the 74AHC374PW,118?
The device supports up to 130 MHz maximum clock frequency at VCC = 4.5–5.5 V with 15 pF load, as specified in Table 7. This assumes clean signal edges and proper PCB layout; actual system-level frequency may be limited by board trace capacitance and driver strength.
Can the 74AHC374PW,118 operate with a 3.3 V supply and interface with 5 V inputs?
Yes - its inputs are overvoltage tolerant up to 5.5 V regardless of VCC, so it can safely accept 5 V logic signals while powered from 3.3 V. Output VOH remains ~3.3 V, requiring level translation if driving 5 V loads.
Is the 74AHC374PW,118 pin-compatible with the 74AHCT374PW,118?
Yes - both share identical TSSOP20 pinout (SOT360-1), same pin functions, and matching AC/DC specifications except input threshold levels. The AHCT variant requires TTL-compatible inputs; AHC uses CMOS thresholds.
Does the 74AHC374PW,118 include ESD protection, and what level is certified?
Yes - it features HBM ESD protection exceeding 2000 V (ANSI/ESDA/JEDEC JS-001 Class 2) and CDM protection exceeding 1000 V (JS-002 Class C3), as verified in Section 2 and Table 6 of the official Nexperia datasheet Rev. 4.
