Product details
Overview
74AHC74PW-Q100 from Nexperia is an automotive-qualified dual positive-edge-triggered D-type flip-flop with asynchronous set (active LOW) and reset (active LOW), complementary Q/Q̅ outputs, Schmitt-trigger clock inputs, and CMOS-level input compatibility. It operates from 2.0 V to 5.5 V, delivers ≤9.5 ns propagation delay at 5 V/50 pF, and supports 110 MHz maximum frequency in automotive-grade temperature range (−40 °C to +125 °C). It is used in engine control unit (ECU) timing synchronization and ADAS sensor data latching.
For engineers reviewing the 74AHC74PW-Q100 datasheet, 74AHC74PW-Q100 pinout, 74AHC74PW-Q100 application, or 74AHC74PW-Q100 equivalent, this page provides verified functional identity, TSSOP14 package mapping, 14-pin terminal roles, propagation delay and setup/hold timing under automotive conditions, and validated AEC-Q100 Grade 1 compliance - all confirmed against Nexperia's Rev. 5 (7 March 2024) product data sheet.
Technical Context
This device implements two independent edge-triggered D flip-flops sharing no internal logic coupling, each with fully asynchronous SD and RD inputs that override clock and data states. Its Schmitt-trigger clock input ensures robust operation with slow-rising signals common in automotive harness environments.
It uses high-speed Si-gate CMOS technology compliant with JEDEC Std. 7-A, achieving balanced tPLH/tPHL delays and supporting mixed-voltage interfacing via input tolerance up to 7.0 V regardless of VCC. The 74AHC variant accepts CMOS-level inputs (VIH ≥ 3.85 V at VCC = 5.5 V), distinguishing it from the TTL-compatible 74AHCT74PW-Q100.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74AHC - CMOS-level compatible, 2.0–5.5 V supply, low static current (≤40 μA) |
| Propagation Delay (tpd) | ≤9.5 ns at VCC = 4.5–5.5 V, CL = 50 pF - enables reliable sampling of 110 MHz clock domains |
| Set-up Time (tsu) | 5.0 ns minimum at VCC = 4.5–5.5 V - defines minimum data stability window before clock edge |
| Hold Time (th) | 0.5 ns minimum at VCC = 4.5–5.5 V - constrains post-edge data stability for metastability avoidance |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C) - qualified for powertrain and chassis control modules |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets automotive board-level ESD immunity requirements |
| Input Voltage Range | −0.5 V to +7.0 V - allows safe interfacing with higher-voltage sensors without level shifters |
Pinout & Package
TSSOP14 package (SOT402-1): plastic thin shrink small outline, 14 leads, 4.4 mm body width, 0.65 mm lead pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1RD | Asynchronous reset (Flip-flop 1) | Active-LOW override: forces 1Q = LOW, 1Q̅ = HIGH independent of clock or data |
| VCC | Positive supply | 2.0–5.5 V rail; powers both flip-flops and input buffers; decoupling required within 10 mm |
| 1D | Data input (Flip-flop 1) | Samples on rising clock edge; must be stable ≥5 ns before CP transition at 5 V |
| 2RD | Asynchronous reset (Flip-flop 2) | Independent active-LOW reset for second section; no crosstalk with Flip-flop 1 |
| 1CP | Clock input (Flip-flop 1) | Schmitt-triggered rising-edge detector; tolerates rise/fall times up to 20 ns/V |
| 2D | Data input (Flip-flop 2) | Functionally identical to 1D but isolated; enables dual-channel synchronous latching |
| 1SD | Asynchronous set (Flip-flop 1) | Active-LOW override: forces 1Q = HIGH, 1Q̅ = LOW regardless of CP or 1D state |
| 2CP | Clock input (Flip-flop 2) | Independent Schmitt-triggered clock; allows staggered or identical timing control per channel |
| 1Q | True output (Flip-flop 1) | Reflects sampled 1D state after 1CP rising edge; drives standard CMOS loads (≤8 mA) |
| 2SD | Asynchronous set (Flip-flop 2) | Independent active-LOW set; enables dual-channel initialization or fault recovery |
| 1Q̅ | Complement output (Flip-flop 1) | Logical inverse of 1Q; usable as enable/disable signal or differential bus driver |
| 2Q | True output (Flip-flop 2) | Matches 1Q timing spec; supports parallel data capture in dual-sensor systems |
| GND | Ground reference | 0 V return path; requires low-inductance connection to minimize ground bounce in switching |
| 2Q̅ | Complement output (Flip-flop 2) | Guaranteed complementary to 2Q; supports differential signaling or XOR logic generation |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 certified - validated for continuous operation at +125 °C ambient in engine bay applications |
| Schmitt-trigger clock inputs | Enables reliable triggering with noisy or slow-rising signals (e.g., camshaft position sensors); eliminates need for external hysteresis |
| Input overvoltage tolerance | Accepts −0.5 V to +7.0 V on all inputs - permits direct interface with 5 V or 12 V sensor outputs without clamping diodes |
| Asynchronous control independence | SD/RD pins operate independently per flip-flop and override clock/data - critical for fail-safe ECU reset sequencing |
| Low dynamic power | CPD = 12 pF - limits switching power to <1.5 mW at 10 MHz/5 V, reducing thermal load in dense PCB layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHC74D-Q100 | SO14 package (SOT108-1), 3.9 mm body width, higher thermal resistance (10.1 mW/K derating above 100 °C) | Better suited for through-hole prototyping or legacy PCBs with SOIC footprints; lower pin density than TSSOP | Select when board space permits larger footprint or reflow compatibility with existing SO14 tooling is required |
| 74AHC74BQ-Q100 | DHVQFN14 package (SOT762-1), 2.5 × 3 mm body, side-wettable flanks for AOI, 9.6 mW/K derating above 98 °C | Optimized for automated optical inspection and high-density automotive modules where thermal performance is critical | Select for next-generation ADAS ECUs requiring minimal footprint and enhanced solder-joint reliability verification |
Compared with 74AHC74D-Q100 and 74AHC74BQ-Q100, the 74AHC74PW-Q100 balances compactness (TSSOP14), manufacturability (standard reflow profile), and thermal capability - making it optimal for mid-density automotive control boards where SO14 is too large and DHVQFN requires new AOI infrastructure.

FAQ
Is the 74AHC74PW-Q100 pin-compatible with 74AHCT74PW-Q100?
Yes - both share identical TSSOP14 pinout and terminal functions. However, the 74AHC74PW-Q100 uses CMOS-level inputs (VIH ≥ 3.85 V at 5.5 V), while the 74AHCT74PW-Q100 uses TTL-level inputs (VIH ≥ 2.0 V). Swapping them requires verifying source driver compatibility to avoid logic-level misinterpretation.
What is the maximum clock frequency supported at 3.3 V supply?
At VCC = 3.3 V and CL = 15 pF, the 74AHC74PW-Q100 supports up to 125 MHz maximum frequency (typical) and 70 MHz (min) across −40 °C to +125 °C. This is confirmed in Table 7 of the Rev. 5 datasheet for the 74AHC74-Q100 variant under 3.0–3.6 V conditions.
Does the device require external pull-up resistors on SD and RD pins?
No - SD and RD are active-LOW asynchronous inputs with built-in input hysteresis and no internal pull-ups. They must be driven actively to LOW for assertion or held HIGH (≥VIH) by the driving circuit; floating connections will result in undefined reset/set behavior and potential metastability.
Can 74AHC74PW-Q100 drive standard 50 Ω transmission lines directly?
No - its output drive strength is rated for CMOS loads (±8 mA at VCC = 4.5 V), not 50 Ω impedance matching. Direct connection to 50 Ω lines causes signal reflection and excessive current draw. Use a dedicated line driver (e.g., NXPI PCA9306) or series termination resistor for controlled-impedance routing.
