Product details
Overview
74LVC573APW-Q100 from Nexperia is an automotive-grade octal D-type transparent latch with 3-state outputs, 5 V tolerant I/O, and operation across 1.2 V to 3.6 V supply. It features common Latch Enable (LE) and Output Enable (OE) controls, supports mixed-voltage bus interfacing (3.3 V core / 5 V peripherals), and is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C). Used in automotive body control modules for isolating data buses during ECU reconfiguration.
For engineers reviewing the 74LVC573APW-Q100 datasheet, 74LVC573APW-Q100 pinout, 74LVC573APW-Q100 application, or 74LVC573APW-Q100 equivalent, key selection criteria include 5 V tolerance on all I/O pins, ≤6.5 ns propagation delay at 3.3 V, 3-state output disable timing (≤9.5 ns), flow-through TSSOP20 pinout, and AEC-Q100 qualification for under-hood deployment.
Technical Context
This device implements eight independent D-type latches with synchronous transparency controlled by a shared LE signal - data passes through when LE is HIGH and is captured on the HIGH-to-LOW edge. The OE input operates orthogonally: it enables or disables all eight outputs without affecting latch state, supporting hot-swap bus arbitration and multi-master contention management.
Its 5 V tolerant inputs/outputs allow direct connection to legacy 5 V logic while powered from 1.2–3.6 V supplies, eliminating level-shifter components. The CMOS design ensures low static current (≤40 μA at 3.6 V), high-impedance OFF-state (IOZ ≤ ±20 μA), and robust ESD protection (HBM >2000 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - Enables compatibility with modern low-voltage MCUs while retaining 5 V system interoperability. |
| I/O Voltage Tolerance | Up to 5.5 V - Permits safe interfacing with 5 V peripherals even when VCC = 1.2 V, eliminating external level shifters. |
| Propagation Delay (Dn→Qn) | ≤6.2 ns at VCC = 3.0–3.6 V - Supports ≥100 MHz bus handshaking in automotive serial data paths. |
| 3-State Disable Time (OE→Z) | ≤7.5 ns at VCC = 3.0–3.6 V - Ensures fast bus release for time-critical arbitration in CAN/LIN gateway interfaces. |
| Operating Temperature | −40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for engine bay and powertrain control units. |
| Input Leakage Current | ±0.1 μA typical at VCC = 3.6 V, VI = 5.5 V - Minimizes standby power impact in always-on vehicle networks. |
| Power Dissipation Capacitance | 13.2 pF at VCC = 3.0–3.6 V - Enables accurate dynamic power estimation for thermal design in compact ECUs. |
Pinout & Package
TSSOP20 package (SOT360-1): 4.4 mm body width, 0.65 mm pitch, lead-free, RoHS-compliant, with exposed pad option for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output Enable (active LOW) | Asserting LOW enables all Q0–Q7 outputs; HIGH forces high-impedance - critical for bus sharing and hot-plug isolation. |
| 11 (LE) | Latch Enable (active HIGH) | HIGH enables transparent mode; falling edge captures D0–D7 - synchronizes data sampling with system clock edges. |
| 2–9 (D0–D7) | Data Inputs | Independent 5 V tolerant inputs accepting TTL/CMOS logic levels - interface directly with microcontroller GPIO or sensor ADC outputs. |
| 12–19 (Q0–Q7) | 3-State Outputs | True outputs with 5 V tolerant OFF-state - drive 5 V bus lines while powered from 1.8 V or 3.3 V domains. |
| 10 (GND) | Ground Reference | Primary return path for all internal logic and I/O - must be low-inductance connected to system ground plane. |
| 20 (VCC) | Supply Voltage | Core logic supply (1.2–3.6 V); powers internal latches and output drivers - decoupling capacitor required per JEDEC guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation with extended reliability testing - meets automotive functional safety baseline requirements. |
| 5 V tolerant I/O at 1.2 V VCC | Enables direct connection to 5 V sensors or legacy controllers without level translators - reduces BOM count and PCB area in gateway modules. |
| Flow-through pinout (TSSOP20) | D0–D7 and Q0–Q7 arranged for straight PCB trace routing - minimizes crosstalk and simplifies layout in space-constrained ADAS domain controllers. |
| High-impedance when VCC = 0 V | Prevents back-powering of supply rail during power sequencing - essential for fail-safe behavior in multi-rail automotive systems. |
| JEDEC-compliant voltage standards | Supports JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V) - ensures interoperability across voltage-scaled SoCs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal transparent latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC573AQDRQ1 | TI part; identical 5 V tolerance, same 20-pin TSSOP package, but rated only to +105 °C (AEC-Q100 Grade 2). | Not qualified for under-hood use above +105 °C - unsuitable for ECM or transmission control where ambient exceeds 105 °C. | Select when cost sensitivity outweighs extended temperature requirement and system ambient stays ≤105 °C. |
| 74LVC573ABQ-Q100 | Nexperia DHVQFN20 variant; same electrical specs, but 2.5 × 4.5 mm footprint with side-wettable flanks for AOI. | Requires rework of PCB layout and stencil design; better thermal performance but higher assembly complexity. | Select for space-constrained modules needing enhanced thermal dissipation or automated optical inspection capability. |
Compared with SN74LVC573AQDRQ1, the 74LVC573APW-Q100 provides guaranteed operation up to +125 °C for under-hood deployment; versus 74LVC573ABQ-Q100, it offers drop-in compatibility with existing TSSOP footprints while trading some thermal margin for assembly simplicity.

FAQ
What is the maximum allowable input voltage when VCC = 1.2 V?
The 74LVC573APW-Q100 supports input voltages up to 5.5 V regardless of VCC level, including at minimum 1.2 V supply. This 5 V tolerance is achieved via internal clamping structures and is validated per datasheet Table 4 (VI max = +6.5 V absolute max, recommended = +5.5 V), enabling direct interfacing with 5 V sensors or legacy controllers without external protection.
Can OE and LE be driven simultaneously from the same microcontroller pin?
No - OE and LE serve orthogonal functions and must be controlled independently. LE (active HIGH) controls data capture timing, while OE (active LOW) controls output driver state. Driving them from one pin would prevent transparent mode operation (LE HIGH + OE LOW) or disable mode (LE any + OE HIGH), breaking fundamental latch behavior. Separate GPIO control is required for full functionality.
Does this device support hot insertion into a live 5 V bus?
Yes - the 74LVC573APW-Q100 supports hot insertion when powered down (VCC = 0 V), as confirmed by its "high-impedance when VCC = 0 V" feature and IOFF leakage ≤ ±20 μA at VI/VO = 5.5 V. This prevents back-powering and bus contention during live board replacement in modular automotive ECUs, provided OE is held HIGH during insertion.
What is the worst-case output skew between Q0 and Q7?
The worst-case output skew (tsk(0)) is guaranteed ≤1.5 ns across temperature (−40 °C to +125 °C) at VCC = 3.0–3.6 V, per datasheet Table 7. This skew applies to any two outputs switching in the same direction and is ensured by matched internal routing and driver design - critical for maintaining data validity in parallel bus applications like display interfaces.
