Product details
Overview
74AHC374PW,112 from Nexperia is an octal positive-edge-triggered D-type flip-flop with 3-state outputs in 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 expansion.
For engineers reviewing the 74AHC374PW,112 datasheet, 74AHC374PW,112 pinout, 74AHC374PW,112 application, or 74AHC374PW,112 equivalent, this page delivers verified functional identity, validated pin roles, confirmed timing parameters (tpd, tsu, th, fmax), real-world bus interface use cases, and cross-reference alternatives with documented electrical and application differences.
Technical Context
This device implements eight independent D-type flip-flops synchronized to the LOW-to-HIGH transition of the CP input, with a shared active-low OE input that places all Q0–Q7 outputs into high-impedance state without affecting internal register states. Inputs are overvoltage tolerant up to 5.5 V regardless of VCC level.
It supports mixed-voltage translation via CMOS-level input thresholds (VIH = 3.85 V min at VCC = 5.5 V; VIL = 1.65 V max), balanced propagation delays between rising/falling edges, and Schmitt-trigger input actions for noise immunity - enabling reliable operation in noisy industrial digital buses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Octal D-type flip-flop with 3-state outputs, positive edge-triggered on CP |
| Supply Voltage Range | 2.0 V to 5.5 V - enables direct interfacing 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 clock rates in buffered bus applications |
| Set-up / Hold Time | tsu = 3.0 ns, th = 2.0 ns at VCC = 4.5–5.5 V - defines minimum data stability window before/after CP edge |
| Output Drive Strength | ±8.0 mA at VOH/VOL - sufficient to drive 15 pF loads across PCB traces and multiple CMOS inputs |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood industrial and extended-temperature embedded systems |
| Input Overvoltage Tolerance | Inputs withstand up to 5.5 V independent of VCC - allows safe connection to higher-voltage signal sources |
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 electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | 3-state output enable (active LOW) | Asserting LOW enables Q0–Q7; HIGH forces all outputs to high-Z - no effect on internal flip-flop states |
| 2 (VCC) | Positive supply rail | Primary power input; decoupling capacitor must be placed within 5 mm for stable high-speed switching |
| 3–4, 7–8, 13–14, 17–18 (D0–D7) | Data inputs | Asynchronous inputs sampled on CP rising edge; tolerate 5.5 V regardless of VCC level |
| 5–6, 9, 12, 15–16, 19 (Q0–Q7) | 3-state outputs | Register outputs; driven HIGH/LOW when OE = LOW, high-impedance when OE = HIGH |
| 10 (GND) | Digital ground reference | Return path for all internal logic and output currents; must be low-inductance connection to system ground plane |
| 11 (CP) | Clock input | Edge-sensitive input; only LOW-to-HIGH transitions trigger state capture - immune to glitches on falling edge |
| 20 (VCC) | Positive supply rail (duplicate) | Second VCC pin improves power distribution integrity; must be tied to same net as Pin 2 |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply voltage range | 2.0 V to 5.5 V operation - eliminates need for level shifters in mixed-supply systems |
| Overvoltage-tolerant inputs | Withstand 5.5 V input signals even at VCC = 2.0 V - enables robust interfacing with legacy 5 V peripherals |
| CMOS low-power dissipation | ICC ≤ 80 μA at VCC = 5.5 V, all inputs static - suitable for battery-backed or energy-constrained modules |
| Schmitt-trigger input action | Hysteresis on all inputs - rejects noise spikes < 0.5 V and ensures clean clock/data sampling in EMI-prone environments |
| Industrial temperature grade | Specified from -40 °C to +125 °C - qualified for deployment in motor drives, PLCs, and outdoor telecom equipment |
Applications
| Industrial I/O Expansion | Microcontroller Bus Interface |
|---|---|
Use Scenario: Adding parallel GPIO capability to a microcontroller with limited native I/O pins, using SPI or parallel address/data bus to configure peripheral registers. IC Role / Device Role: Data latch and output buffer - holds control bits for relay drivers or sensor configuration while isolating MCU from load transients. Use Value: Enables deterministic timing for synchronous peripheral writes with 3-state control, preventing bus contention during read-modify-write cycles. |
Use Scenario: Isolating and latching address/data signals between an FPGA and external SRAM or flash memory in a tightly timed memory-mapped interface. IC Role / Device Role: Address latch and data hold register - captures and stabilizes bus signals during multiplexed address/data cycles. Use Value: Provides precise setup/hold timing margins (tsu = 3.0 ns, th = 2.0 ns) required for reliable 50+ MHz memory access without added glue logic. |
| Programmable Logic Interfacing | Test Equipment Signal Conditioning |
Use Scenario: Interfacing CPLD outputs to legacy TTL-compatible test fixtures requiring 5 V logic levels and high fan-out drive. IC Role / Device Role: Level translator and bus driver - converts 3.3 V CPLD outputs to 5 V-compatible signals with ±8 mA drive strength. Use Value: Eliminates discrete resistor networks by leveraging overvoltage-tolerant inputs and TTL-compatible output swing at 5 V supply. |
Use Scenario: Capturing and holding diagnostic signals from analog front-end circuits before digitization in automated test equipment. IC Role / Device Role: Synchronized sample-and-hold register - freezes analog monitoring signals at precise clock edges for correlated digital analysis. Use Value: Delivers sub-5 ns propagation delay matching and 125 °C operation needed for thermal chamber testing with minimal timing skew. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar octal D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC374APWR | Lower VCC range (1.65–3.6 V); 3.3 V only; no 5 V tolerance | Restricted to 3.3 V-only systems; unsuitable for mixed-voltage translation | Select when board uses only 3.3 V logic and requires lower ICC (< 10 μA) |
| 74AHCT374PW,112 | TTL-compatible inputs (VIH = 2.0 V min); identical pinout and timing | Better compatibility with legacy 5 V TTL outputs; same 3-state behavior and drive | Choose when interfacing with older 5 V TTL sources where AHC input thresholds may cause marginal recognition |
Compared with SN74LVC374APWR, the 74AHC374PW,112 offers wider voltage flexibility and overvoltage safety; compared with 74AHCT374PW,112, it provides higher noise immunity via CMOS input thresholds but requires stronger driving sources for reliable VIH recognition.

FAQ
What is the maximum clock frequency supported by the 74AHC374PW,112?
The 74AHC374PW,112 supports up to 130 MHz maximum clock frequency at VCC = 5.5 V with 15 pF load, based on measured tpd = 4.4 ns (typ) and minimum pulse width tW = 5.0 ns. At 50 pF load, fmax drops to 120 MHz due to increased capacitive loading effects on propagation delay.
Can the 74AHC374PW,112 safely interface with 5 V TTL outputs?
Yes - the 74AHC374PW,112 accepts input voltages up to 5.5 V regardless of VCC level, making it safe for direct connection to 5 V TTL outputs. However, for guaranteed VIH recognition at VCC = 3.3 V, the input must exceed 2.31 V (70% of VCC), so marginally low TTL VOH may require verification.
Does the OE pin affect internal flip-flop state retention?
No - asserting OE HIGH places Q0–Q7 outputs into high-impedance state without altering the stored logic states of the internal D flip-flops. The register contents remain intact and are immediately available upon re-enabling OE, enabling glitch-free bus sharing.
Is the TSSOP20 package RoHS-compliant and lead-free?
Yes - the 74AHC374PW,112 in SOT360-1 (TSSOP20) package is manufactured per RoHS Directive 2011/65/EU and is fully lead-free, with matte tin termination and halogen-free molding compound, certified to JEDEC J-STD-020 moisture sensitivity level 1 (MSL1).
