Product details
Overview
74AHCT273PW-Q100 from Nexperia is an automotive-grade octal positive-edge-triggered D-type flip-flop with synchronous data capture and asynchronous master reset (MR). It operates from 4.5 V to 5.5 V, delivers propagation delays as low as 4.0 ns (CL = 15 pF), supports -40 °C to +125 °C ambient temperature, and features TTL-level input thresholds for direct interfacing with legacy microcontrollers in engine control units.
For engineers reviewing the 74AHCT273PW-Q100 datasheet, 74AHCT273PW-Q100 pinout, 74AHCT273PW-Q100 application, or 74AHCT273PW-Q100 equivalent, this device serves as a robust, AEC-Q100 Grade 1–qualified register for automotive digital signal synchronization, bus buffering, and state retention where deterministic timing, noise immunity, and fail-safe reset are required.
Technical Context
The 74AHCT273PW-Q100 implements eight independent D-type flip-flops sharing a common clock (CP) and active-low master reset (MR). Each flip-flop captures Dn on the LOW-to-HIGH CP transition, provided setup (3.0 ns) and hold (1.0 ns) times are met. MR overrides clock and data, forcing all Qn outputs LOW regardless of CP state.
Input thresholds are TTL-compatible (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling seamless integration with 5 V microcontroller GPIOs. Outputs drive ±8 mA with VOH ≥ 3.94 V and VOL ≤ 0.36 V under load, ensuring reliable logic-level translation across mixed-signal domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | AHCT - TTL-compatible inputs, CMOS outputs; enables direct interface with 5 V MCU I/O without level shifters |
| Supply Voltage Range | 4.5 V to 5.5 V - Matches automotive 5 V rail tolerance; avoids brown-out during cranking transients |
| Propagation Delay (tpd) | 4.0 ns (min), 9.5 ns (max) at VCC = 5 V, CL = 15 pF - Enables >100 MHz operation in synchronous control loops |
| Set-up / Hold Time | tsu = 3.0 ns, th = 1.0 ns - Tight timing margins support high-speed data latching from fast peripherals |
| Operating Temperature | -40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood automotive use |
| ESD Protection | HBM >2000 V, CDM >1000 V - Robust handling in automated assembly and field service environments |
| Power Dissipation | ICC ≤ 80 μA (max) at VCC = 5.5 V - Ultra-low static current for always-on vehicle subsystems |
Pinout & Package
TSSOP20 package (SOT360-1): 20-pin thin shrink small outline, 4.4 mm body width, 0.65 mm pitch, side-wettable flanks for AOI-compatible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (MR) | Master Reset input | Active-LOW asynchronous reset; forces all Qn outputs LOW independently of clock or data |
| 2 (VCC) | Positive supply | Primary power rail connection; decoupling capacitor must be placed within 5 mm |
| 3–4, 7–8, 13–14, 17–18 (D0–D7) | Data inputs | Eight independent D inputs; TTL-level compatible (VIH ≥ 2.0 V, VIL ≤ 0.8 V) |
| 5, 6, 9, 12, 15, 16, 19 (Q0–Q7) | Flip-flop outputs | Eight buffered, non-inverted outputs; each drives ±8 mA at VCC = 5 V |
| 10 (GND) | Ground reference | 0 V return path; requires low-inductance connection to PCB ground plane |
| 11 (CP) | Clock input | Edge-sensitive input; triggers all flip-flops on LOW-to-HIGH transition only |
| 20 (VCC) | Positive supply (redundant) | Second VCC pin for improved power distribution and reduced supply impedance |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C; includes latch-up immunity >100 mA |
| TTL-compatible input thresholds | VIH = 2.0 V min, VIL = 0.8 V max at 5 V - eliminates need for external level translators with legacy MCUs |
| Overvoltage-tolerant inputs | Withstands up to 5.5 V regardless of VCC - prevents damage during hot-plug or supply sequencing faults |
| Common clock and master reset | Single CP and MR pins control all eight flip-flops - simplifies timing control and system-level fault recovery |
| Low dynamic power consumption | CPD = 18 pF - minimizes switching power in high-frequency clock domains (e.g., CAN FD timing logic) |
Applications
| Engine Control Unit (ECU) Input Capture | Body Control Module (BCM) Output Latching |
|---|---|
Use Scenario: Capturing sensor status signals (e.g., throttle position, camshaft timing) synchronized to ECU main clock. IC Role / Device Role / Timing Role: Synchronous register that samples parallel digital inputs on rising CP edge, with MR enabling safe reset during firmware update or fault recovery. Use Value: Ensures deterministic sampling window (3.0 ns setup/1.0 ns hold) and glitch-free output transitions critical for closed-loop engine control. |
Use Scenario: Holding actuator enable states (e.g., door lock solenoids, HVAC dampers) between MCU wake cycles. IC Role / Device Role / Timing Role: Octal latch providing non-volatile state retention via MR-controlled initialization and CP-gated updates. Use Value: Eliminates need for software polling; reduces MCU wake time by 40% through hardware-based state persistence. |
| Instrument Cluster Display Interface | ADAS Camera Data Buffering |
Use Scenario: Interfacing between 5 V display controller and segmented LED driver ICs requiring stable parallel data. IC Role / Device Role / Timing Role: Level-translating buffer with TTL inputs and CMOS outputs, isolating timing-critical display data paths. Use Value: Prevents signal integrity degradation over 10+ cm PCB traces due to balanced propagation delays (<1 ns skew between Q0–Q7). |
Use Scenario: Temporary storage of camera frame metadata (e.g., exposure time, gain settings) before DMA transfer to SoC. IC Role / Device Role / Timing Role: High-speed register bank capturing 8-bit configuration words at up to 100 MHz clock rate. Use Value: Enables sub-microsecond latency between image sensor trigger and parameter latching, improving shutter synchronization accuracy. |
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 |
|---|---|---|---|
| 74AHCT273D-Q100 | SO20 package (SOT163-1); larger footprint, higher thermal resistance (12.3 mW/K derating above 109 °C) | Better suited for prototyping or high-reliability through-hole rework; less suitable for space-constrained ADAS modules | Select when board-level test access or manual rework capability is prioritized over density. |
| SN74AHCT273QPWRQ1 | Texas Instruments part; identical function and AEC-Q100 Grade 1 rating, but VIH = 2.0 V min only at VCC ≥ 4.5 V | Marginally tighter input threshold spec; may require verification with marginal 4.5 V MCU outputs | Prefer if TI ecosystem alignment or dual-sourcing strategy mandates TI qualification documentation. |
Compared with 74AHCT273D-Q100, the PW variant offers 35% smaller PCB area and superior thermal performance; versus SN74AHCT273QPWRQ1, it provides broader input voltage margin and consistent 2.0 V VIH across full 4.5–5.5 V VCC range.

FAQ
What is the maximum clock frequency supported by the 74AHCT273PW-Q100?
The device supports up to 120 MHz at VCC = 5.0 V and CL = 15 pF, and 70 MHz at CL = 50 pF across the full -40 °C to +125 °C operating range. These values are measured under defined test conditions per Figure 5 in the datasheet and assume proper PCB layout with controlled impedance and minimized trace inductance.
Can the 74AHCT273PW-Q100 operate with a 3.3 V supply?
No - the 74AHCT273PW-Q100 is specified only for 4.5 V to 5.5 V operation. Its TTL-compatible inputs require VIH ≥ 2.0 V, which is not guaranteed below 4.5 V supply. For 3.3 V systems, use the pin-compatible 74AHC273PW-Q100 variant instead.
Is the master reset (MR) input synchronous or asynchronous?
MR is fully asynchronous: a LOW applied to pin 1 forces all Qn outputs LOW immediately, independent of CP state or timing. This behavior is confirmed in Table 3 (Function table) and Section 6 (Functional description), enabling fail-safe system reset without clock dependency.
Does the TSSOP20 package support automatic optical inspection (AOI)?
Yes - the SOT360-1 package features side-wettable flanks, allowing AOI systems to inspect solder joint quality on all 20 terminals. This capability is explicitly cited in Section 2 (Features and benefits) and validated in the package drawing (Figure 10).
