Nexperia USA Inc. 74LVC16373ADGV-Q1J

Overview

74LVC16373ADGV-Q1J from Nexperia is a 16-bit D-type transparent latch with dual 8-bit latch enable (1LE/2LE) and output enable (1OE/2OE) controls, 5.5 V tolerant I/O, 1.2 V to 3.6 V supply operation, and AEC-Q100 Grade 1 qualification for automotive body control modules requiring level translation between 3.3 V microcontrollers and 5 V sensor interfaces.

For engineers reviewing the 74LVC16373ADGV-Q1J datasheet, 74LVC16373ADGV-Q1J pinout, 74LVC16373ADGV-Q1J application, or 74LVC16373ADGV-Q1J equivalent, key selection criteria include 5 V-tolerant input voltage range (−0.5 V to +5.5 V), bus hold on data inputs (74LVCH variant only), IOFF partial power-down support, Schmitt-trigger inputs for slow-edge immunity, and guaranteed −40 °C to +125 °C operation in TVSOP48 packaging.

Technical Context

This device implements two independent 8-bit transparent latches sharing a common 48-pin TVSOP package, each with dedicated latch enable (active HIGH) and output enable (active LOW) signals. Its dual-control architecture enables selective latching and tri-state control of either byte without affecting the other.

It supports mixed-voltage system interfacing via 5.5 V tolerant inputs/outputs while operating from a 1.2 V–3.6 V supply, and integrates IOFF circuitry to disable outputs during power-down, preventing backflow current. Bus hold (on 74LVCH version only) eliminates external pull-ups on unused data inputs.

Key Specifications

Pinout & Package

74LVC16373ADGV-Q1J uses the SOT480-1 (TVSOP48) package: 48-lead plastic thin shrink small outline package, 4.4 mm body width, 0.4 mm lead pitch, 1.1 mm max height. Pin numbering follows standard counter-clockwise layout with pin 1 index marker.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit transparent latch applications.

Compared with 74LVCH16373ADGV-Q100, the subject part lacks bus hold-requiring external termination if inputs float-but matches all timing, voltage, and automotive qualification specs. SN74LVC16373APAG offers higher thermal headroom in a larger TSSOP package but sacrifices compactness and adds no functional advantage for space-constrained automotive modules.

FAQ

Is 74LVC16373ADGV-Q1J pin-compatible with 74LVCH16373ADGV-Q100?

Yes-both share identical SOT480-1 (TVSOP48) pinout, electrical specifications, and AEC-Q100 qualification. The only functional difference is that the LVCH variant includes bus hold circuitry on data inputs; the LVC variant does not. No PCB redesign is needed for substitution, though floating D-inputs may require external pull resistors when using the LVC version.

What is the maximum data rate supported by this latch in transparent mode?

In transparent mode (nLE = HIGH), the device supports sustained data rates up to ~100 MHz based on worst-case 5.5 ns propagation delay (VCC = 3.0–3.6 V, −40 °C to +125 °C). However, reliable operation requires meeting setup/hold times (tsu = 2.0 ns, th = +0.9 ns) relative to LE edge timing, limiting practical throughput to ≤80 MHz in synchronous capture applications.

Can this device be used in a 5 V-only system?

No-it requires VCC between 1.2 V and 3.6 V and is not rated for 5 V supply. However, its inputs tolerate up to 5.5 V regardless of VCC, enabling safe connection to 5 V signal sources (e.g., legacy sensors) while powered from 3.3 V or lower. Outputs swing rail-to-rail within VCC/GND, so external level-shifting is required to drive true 5 V loads.

Does the IOFF feature work when VCC is disconnected but inputs remain at 5 V?

Yes-the IOFF circuitry activates automatically when VCC drops below ~0.8 V, forcing outputs into high-impedance state even if inputs are held at 5.5 V. Measured IOFF leakage is ≤±10 μA under these conditions, preventing back-current damage to upstream 5 V drivers during power sequencing or fault events.
