Product details
Overview
74LVC373APW-Q100 from Nexperia is an automotive-grade octal D-type transparent latch with 3-state outputs, latch enable (LE) and output enable (OE) controls, 1.2 V to 3.6 V supply operation, 5.5 V overvoltage-tolerant I/O, and Schmitt-trigger inputs for noise immunity. It functions as a data latching and bus isolation interface in automotive body control modules requiring level translation between 3.3 V microcontrollers and 5 V sensors.
For engineers reviewing the 74LVC373APW-Q100 datasheet, 74LVC373APW-Q100 pinout, 74LVC373APW-Q100 application, or 74LVC373APW-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (-40 °C to +125 °C), IOFF partial power-down capability, TSSOP20 package with side-wettable flanks for AOI, and 5 V tolerant I/O enabling mixed-voltage system interfacing without external level shifters.
Technical Context
This device implements eight independent D-type latches with transparent mode when LE is HIGH and edge-triggered capture on LE HIGH-to-LOW transition. Each latch output drives a 3-state buffer controlled separately by OE (active LOW), allowing dynamic bus contention avoidance without affecting internal latch states.
Schmitt-trigger inputs ensure robust operation with slow-rising signals common in automotive harnesses, while the IOFF circuit guarantees high-impedance outputs and zero backflow current during VCC = 0 V conditions - critical for hot-swap and power sequencing in ADAS domain controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.2 V to 3.6 V - supports low-power 1.2 V logic domains and standard 3.3 V systems without level-shifting overhead. |
| Input voltage tolerance | Up to 5.5 V - enables direct connection to legacy 5 V peripherals and sensors in mixed-voltage automotive ECUs. |
| Propagation delay (D→Q) | 1.5 ns to 8.5 ns (VCC = 3.0–3.6 V) - ensures timing-critical data capture in real-time vehicle network gateways. |
| IOFF leakage current | ±10 μA max at VCC = 0 V - prevents damaging back-current during partial power-down in multi-rail automotive subsystems. |
| ESD protection | HBM > 2000 V, CDM > 1000 V - meets stringent automotive ESD immunity requirements per ISO 10605. |
| Operating temperature | -40 °C to +125 °C - qualified for under-hood and transmission control unit environments per AEC-Q100 Grade 1. |
| Output drive strength | ±24 mA at VCC = 3.0 V - sufficient to drive multiple CMOS loads or short PCB traces in distributed body electronics. |
Pinout & Package
TSSOP20 package (SOT360-1): 20-pin plastic thin shrink small outline, 4.4 mm body width, side-wettable flanks for automated optical inspection of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output enable input | Active LOW control: asserts high-impedance state on all Q0–Q7 outputs independently of latch state. |
| 2 (VCC) | Positive supply | 1.2 V–3.6 V logic supply; powers internal logic and output buffers; IOFF active when VCC = 0 V. |
| 3–4, 7–8, 13–14, 17–18 (D0–D7) | Data inputs | Eight asynchronous inputs accepting 0–5.5 V signals; Schmitt-triggered for noise margin in electrically noisy chassis environments. |
| 5–6, 9, 12, 15–16, 19 (Q0–Q7) | Latched outputs | Eight 3-state outputs reflecting stored D-input values when OE = LOW and LE has captured data. |
| 10 (GND) | Ground reference | 0 V return path for logic and output currents; required for proper IOFF and ESD clamp operation. |
| 11 (LE) | Latch enable input | Active HIGH: enables transparent mode; HIGH-to-LOW edge captures and holds Dn values for subsequent readout. |
| 20 (VCC) | Supply voltage | Duplicate VCC pin for improved power integrity and reduced IR drop across the 20-pin TSSOP layout. |
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 per JEDEC JESD47. |
| IOFF partial power-down | Outputs automatically enter high-Z state with <±10 μA leakage when VCC = 0 V - essential for safe hot-plug and multi-supply domain isolation. |
| 5.5 V overvoltage-tolerant I/O | Inputs and outputs withstand up to 5.5 V regardless of VCC setting (1.2–3.6 V), eliminating need for external clamping diodes in 5 V sensor interfaces. |
| Schmitt-trigger inputs | Hysteresis ≥0.3 V typical - rejects noise spikes and slow edges from long wiring harnesses in door modules and lighting controllers. |
| Side-wettable flanks (SWF) | TSSOP20 package geometry enables automated X-ray and AOI verification of solder joint quality - critical for automotive manufacturing traceability. |

FAQ
Can the 74LVC373APW-Q100 operate with a 1.2 V supply while interfacing with 5 V inputs?
Yes. The device is fully specified from 1.2 V to 3.6 V supply and supports 5.5 V overvoltage-tolerant inputs. At VCC = 1.2 V, VIH is guaranteed at 1.08 V and VIL at 0.12 V, ensuring reliable recognition of 5 V logic levels without external biasing or clamping components.
What is the purpose of the IOFF feature, and how does it behave during power-down?
The IOFF circuit disables all outputs and limits leakage to ±10 μA maximum when VCC = 0 V, preventing reverse current flow through powered-down outputs into live system buses. This protects downstream circuitry during partial power-down sequences common in automotive domain controllers with independent rail management.
Does the TSSOP20 package support automated optical inspection (AOI) of solder joints?
Yes. The SOT360-1 (TSSOP20) package features side-wettable flanks - exposed copper on the vertical package edges - enabling high-accuracy AOI systems to verify solder fillet formation and wetting quality without requiring X-ray inspection, meeting Tier 1 automotive manufacturing standards.
How does the Schmitt-trigger input improve noise immunity in automotive applications?
Schmitt-trigger inputs provide ≥0.3 V hysteresis, rejecting fast transients and slow-rising signals caused by long cable runs and electromagnetic interference in vehicle harnesses. This eliminates false triggering from switch bounce or EMI-induced glitches in door module and lighting control circuits.
