Product details
Overview
74LVC823ABQ-Q100 from Nexperia is a 9-bit automotive-grade D-type flip-flop with positive edge-triggered clock, master reset, clock enable, and 3-state outputs in DHVQFN24 package. It operates from 1.2 V to 3.6 V supply, supports 5 V tolerant I/O (up to 5.5 V on outputs when disabled), and delivers 150 MHz max frequency at 3.0–3.6 V for bus-oriented data latching in vehicle control modules.
For engineers reviewing the 74LVC823ABQ-Q100 datasheet, 74LVC823ABQ-Q100 pinout, 74LVC823ABQ-Q100 application, or 74LVC823ABQ-Q100 equivalent, key selection criteria include 5 V tolerance for mixed-voltage interfacing, AEC-Q100 Grade 1 qualification (-40 °C to +125 °C), independent register/3-state buffer operation, and flow-through pinout for PCB routing efficiency.
Technical Context
This device implements nine synchronous D-type flip-flops sharing one common clock (CP) input, with separate master reset (MR) and clock enable (CE) controls. Each flip-flop samples its D-input on the LOW-to-HIGH CP transition when CE is LOW, and holds state when CE is HIGH - enabling precise timing control in automotive serial data paths.
The 3-state output buffer is fully decoupled from register operation: OE controls output enable/disable independently of MR or CP activity, allowing dynamic bus contention avoidance. Inputs accept 3.3 V or 5 V logic levels, and outputs tolerate up to 5.5 V when disabled - supporting bidirectional voltage translation between 3.3 V microcontrollers and 5 V legacy peripherals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 9-bit positive edge-triggered D-type flip-flop with 3-state outputs |
| Supply Voltage Range | 1.2 V to 3.6 V - enables direct interface with low-voltage MCUs while maintaining compatibility with JEDEC standards JESD8-7A/5A/C |
| I/O Voltage Tolerance | 5 V tolerant inputs/outputs - allows safe connection to 5 V systems without level shifters; outputs withstand 5.5 V when disabled |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for engine bay and ADAS ECU deployment |
| Max Clock Frequency | 150 MHz at VCC = 3.0–3.6 V - supports high-speed data capture in CAN FD gateway buffers and sensor fusion interfaces |
| Propagation Delay (tpd) | 1.5 ns (min) to 8.0 ns (max) at VCC = 3.0–3.6 V - ensures tight timing margins in synchronized multi-signal acquisition |
| Output Skew (tsk(o)) | ≤1.5 ns - guarantees simultaneous valid output transitions across all 9 bits for deterministic bus loading |
Pinout & Package
DHVQFN24 package (SOT815-1), 3.5 × 5.5 × 0.85 mm body, side-wettable flanks for AOI-compatible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference (0 V); thermal pad not electrically required but may be floated or tied to GND |
| 2–10 | D0–D8 | Asynchronous data inputs - sampled on rising CP edge when CE = LOW |
| 11 | MR | Active-low master reset - forces all Qn outputs LOW regardless of CP or CE state |
| 12 | GND | Second ground terminal - improves noise immunity and thermal dissipation |
| 13 | CP | Positive edge-triggered clock input - initiates sampling of Dn inputs on LOW-to-HIGH transition |
| 14 | CE | Active-low clock enable - disables clock action when HIGH, preserving register state |
| 15–23 | Q0–Q8 | 3-state flip-flop outputs - driven only when OE = LOW; high-impedance when OE = HIGH |
| 24 | VCC | Power supply input - supports 1.2–3.6 V operation with CMOS low-power consumption |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including thermal cycling and humidity testing |
| 5 V tolerant I/O | Enables direct interconnection with 5 V legacy sensors, displays, or communication ICs without external level translators |
| Independent register and 3-state control | OE toggles output drivers without affecting stored data - critical for hot-swappable bus arbitration |
| Flow-through pinout architecture | Input pins (D0–D8) and output pins (Q0–Q8) placed on opposite sides - minimizes trace crossovers and signal integrity loss |
| Side-wettable flanks (DHVQFN24) | Enables automated optical inspection (AOI) of solder joints - essential for zero-defect automotive manufacturing compliance |
Applications
| Automotive Body Control Module | ADAS Sensor Interface Hub |
|---|---|

| Engine Control Unit (ECU) Diagnostics Port | Infotainment Display Backlight Driver Interface |
|
Use Scenario: Isolating diagnostic I/O lines (e.g., OBD-II K-line, CAN TX/RX enable) during firmware updates to prevent bus corruption. IC Role / Device Role / Timing Role: 3-state bus isolator with independent OE control, decoupled from internal register state. Use Value: OE-driven high-impedance mode blocks signal propagation without resetting stored diagnostic configuration bits. |
Use Scenario: Driving PWM-controlled LED backlight segments from a 3.3 V display controller while interfacing with 5 V LED driver ICs. IC Role / Device Role / Timing Role: Voltage-level translating latch buffering PWM duty cycle commands across voltage domains. Use Value: 5 V tolerant outputs directly drive 5 V LED driver enable inputs; 1.2–3.6 V supply matches display controller I/O voltage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 9-bit D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC823APWREP | Same logic function, TSSOP-24 package; no side-wettable flanks; rated for -55 °C to +125 °C | Preferred for space-constrained industrial designs requiring extended temperature range but no AOI requirement | Select when board-level AOI is not mandated and TSSOP hand-soldering or reflow compatibility is prioritized |
| 74LVC823APW-Q100 | Identical functionality and AEC-Q100 Grade 1 rating, but in standard TSSOP-24 (SOT403-1) without side-wettable flanks | Suitable for non-AOI production lines or legacy PCB footprints where DHVQFN rework is impractical | Choose when existing TSSOP layout reuse is critical and automotive AOI capability is not enforced by OEM |
Compared with SN74LVC823APWREP and 74LVC823APW-Q100, the 74LVC823ABQ-Q100 uniquely combines AEC-Q100 Grade 1 qualification with DHVQFN24 side-wettable flanks - making it the only option meeting both zero-defect AOI requirements and engine-bay thermal demands in new automotive platforms.

FAQ
What is the maximum allowable voltage on the Qn outputs when OE is HIGH?
When OE is HIGH, the outputs enter high-impedance OFF-state and tolerate up to 5.5 V - verified per limiting values table (VO output voltage, 3-state). This enables safe connection to 5 V buses without risk of damage, even if the device is unpowered or in standby.
Does MR override CE and CP during active reset?
Yes. A LOW on MR forces all Qn outputs LOW immediately, irrespective of CE or CP state. The functional table confirms "Clear" mode occurs when MR = L, with Qn = L regardless of other inputs - ensuring deterministic fail-safe behavior in automotive fault recovery sequences.
Can this device operate reliably at 1.2 V supply?
Yes. Recommended operating conditions specify VCC down to 1.2 V, and static/dynamic characteristics include data at that voltage (e.g., tpd = 20 ns typ at VCC = 1.2 V). However, max frequency is reduced - fmax = 100 MHz at VCC = 1.65–1.95 V, and not specified below 1.65 V.
Is the thermal pad (Pin 1) required to be soldered to GND?
No. Pin 1 is labeled "GND" but the datasheet explicitly states it is not an electrical ground pin and has no mechanical or electrical requirement for soldering. If soldered, the land must remain floating or be connected to system GND - never left as an unconnected copper island.
