Product details
Overview
74AHC273PW-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 across 2.0–5.5 V supply, supports -40 °C to +125 °C ambient, features overvoltage-tolerant inputs up to 5.5 V, and delivers propagation delays as low as 4.2 ns (VCC = 5.0 V, CL = 15 pF). It is used in automotive body control modules for synchronizing sensor interface signals before CAN or LIN transmission.
For engineers reviewing the 74AHC273PW-Q100 datasheet, 74AHC273PW-Q100 pinout, 74AHC273PW-Q100 application, or 74AHC273PW-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, TSSOP20 package compatibility with AOI inspection, CMOS-level input thresholds, and guaranteed set-up/hold times of 3.0 ns / 1.0 ns at 5 V - critical for reliable sampling of microcontroller GPIO or ADC output latching in safety-critical ECUs.
Technical Context
This device implements eight independent D-type flip-flops sharing a common clock (CP) and active-low master reset (MR), enabling simultaneous state capture or forced clear across all outputs. Its Schmitt-trigger inputs improve noise immunity in noisy automotive harness environments, while overvoltage tolerance allows interfacing between 3.3 V logic domains and 5 V legacy subsystems without level shifters.
The functional behavior is strictly edge-triggered: Qn updates only on LOW-to-HIGH CP transitions when MR is HIGH; a LOW on MR forces all Qn outputs LOW regardless of CP or Dn states. Input leakage remains ≤2.0 μA across temperature, and dynamic power dissipation is governed by CPD = 14 pF, supporting low-power operation in always-on vehicle networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.0 V to 5.5 V - enables direct use with 3.3 V MCU I/O and 5 V analog front-ends without external regulators. |
| Operating temperature | -40 °C to +125 °C - qualified for under-hood ECU placement per AEC-Q100 Grade 1 requirements. |
| Propagation delay (tpd) | 4.2 ns (min, VCC = 5.0 V, CL = 15 pF) - ensures tight timing margins for 100+ MHz system clocks with setup slack. |
| Set-up / hold time | 3.0 ns / 1.0 ns (VCC = 5.0 V) - guarantees reliable sampling of fast-switching digital signals from sensors or transceivers. |
| Input voltage tolerance | Up to 5.5 V regardless of VCC - permits safe connection to 5 V buses while powered from 3.3 V rails. |
| Power dissipation capacitance | CPD = 14 pF - enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal budgeting. |
| ESD rating | HBM >2000 V, CDM >1000 V - meets automotive robustness requirements for assembly and field operation. |
Pinout & Package
TSSOP20 package (SOT360-1), 4.4 mm body width, 0.65 mm pitch, 20-terminal surface-mount with exposed pad not electrically connected.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | MR | Active-low master reset - forces all Q outputs LOW independently of clock; critical for fail-safe initialization. |
| 2 | VCC | Positive supply rail - must be decoupled locally with 100 nF ceramic capacitor near pin 2. |
| 3–4, 7–8, 13–14, 17–18 | D0–D7 | Eight asynchronous data inputs - sampled on rising CP edge if MR is HIGH. |
| 5, 6, 9, 12, 15, 16, 19, 2 | Q0–Q7 | Eight registered outputs - retain state between clock edges; drive loads up to ±8 mA. |
| 10 | GND | Reference ground - requires low-inductance connection to PCB ground plane for signal integrity. |
| 11 | CP | Clock input - LOW-to-HIGH transition triggers simultaneous sampling of all D inputs. |
| 20 | VCC | Redundant supply pin - improves power delivery stability and reduces IR drop in high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including lifetime reliability testing per JEDEC JESD47. |
| Overvoltage-tolerant inputs | Accepts 0–5.5 V input signals irrespective of VCC level - eliminates need for discrete level translators in mixed-voltage designs. |
| Schmitt-trigger inputs | Provides hysteresis on all D and CP inputs - suppresses noise-induced glitches on long PCB traces or cable-connected sensors. |
| Common clock and reset | Single CP and MR control all eight flip-flops - simplifies timing control in LED matrix drivers or multiplexed display interfaces. |
| Side-wettable flanks (SWF) | TSSOP20 package enables automated optical inspection (AOI) of solder joints - supports zero-defect manufacturing in Tier-1 production lines. |

FAQ
Is the 74AHC273PW-Q100 pin-compatible with non-automotive versions like 74AHC273PW?
Yes - the 74AHC273PW-Q100 shares identical pinout, electrical characteristics, and functional behavior with industrial-grade 74AHC273PW, but adds AEC-Q100 Grade 1 qualification, extended temperature validation (-40 °C to +125 °C), and enhanced process controls for automotive reliability.
Can MR be left unconnected if not used?
No - MR is an active-low input with no internal pull-up; leaving it floating risks unintended reset assertion due to noise. It must be tied to VCC via a 10 kΩ resistor or driven actively to ensure predictable operation in automotive EMI environments.
What is the maximum clock frequency supported at 3.3 V supply?
At VCC = 3.3 V and CL = 15 pF, the maximum operating frequency is 120 MHz (typical) with guaranteed minimum of 75 MHz across -40 °C to +125 °C - verified by propagation delay tpd ≤13.6 ns and pulse width tW ≥5.0 ns per datasheet Table 7.
Does the TSSOP20 package require solder paste stencil aperture reduction for the exposed pad?
No - the exposed thermal pad in SOT360-1 is non-functional and electrically isolated; Nexperia specifies no solder connection. Stencil design should omit aperture for terminal 1 index area and avoid bridging to adjacent pins per Figure 10 layout guidelines.
