Product details
Overview
74LVCH16373ADL,118 from Nexperia is a 16-bit D-type transparent latch with 3-state outputs, dual latch enable (1LE/2LE) and dual output enable (1OE/2OE), 5 V tolerant I/O, bus hold on data inputs, and IOFF partial power-down support. It operates from 1.2 V to 3.6 V supply and functions as two independent 8-bit latches or one unified 16-bit latch in high-speed data buffering applications such as memory address/data bus isolation in industrial microcontroller systems.
For engineers reviewing the 74LVCH16373ADL,118 datasheet, 74LVCH16373ADL,118 pinout, 74LVCH16373ADL,118 application, or 74LVCH16373ADL,118 equivalent, key selection criteria include its 5 V tolerant input/output capability across 1.2–3.6 V VCC, bus hold eliminating external pull-ups, IOFF protection during partial power-down, and guaranteed tpd ≤ 4.4 ns at 3.3 V for timing-critical bus interfacing.
Technical Context
This device implements two independent 8-bit transparent latch sections, each controlled by dedicated LE and OE signals, enabling selective latching and tri-state control of half the bus without affecting the other. Its Schmitt-trigger inputs tolerate slow-rising signals, and bus hold circuitry actively maintains logic states on unused D-inputs without external resistors.
The IOFF feature disables outputs when VCC = 0 V, preventing backflow current in mixed-voltage or hot-swap systems. Input voltage tolerance up to 5.5 V allows direct interfacing between 3.3 V logic and legacy 5 V peripherals-no level-shifter required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.2 V to 3.6 V - supports low-power IoT nodes and mixed-supply industrial controllers |
| Input Voltage Tolerance | Up to 5.5 V - enables direct connection to 5 V buses without external level translation |
| tpd (D→Q) | ≤ 4.4 ns at VCC = 3.3 V - ensures sub-5 ns propagation for high-throughput data capture |
| IOFF Leakage | ±10 μA max at VCC = 0 V - guarantees safe operation during system power sequencing |
| Bus Hold Current | ±75 μA at VCC = 3.0 V - eliminates need for 10 kΩ pull-up/down resistors on floating inputs |
| Operating Temp | −40 °C to +125 °C - qualified for under-hood automotive and industrial edge computing |
| ESD Rating | HBM > 2000 V, CDM > 1000 V - meets robustness requirements for manual handling and board assembly |
Pinout & Package
TSSOP48 package (SOT362-1), 48-pin plastic thin shrink small outline, body width 6.1 mm, lead pitch 0.5 mm, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE | Active-low output enable | Independent control of 8-bit output groups; HIGH forces Qn into high-impedance state |
| 1LE, 2LE | Active-high latch enable | Enables transparent mode (Qn follows Dn) when HIGH; latches data on HIGH→LOW transition |
| 1D0–1D7, 2D0–2D7 | Data inputs | 16 total inputs with integrated bus hold - no external biasing needed for unused pins |
| 1Q0–1Q7, 2Q0–2Q7 | Tri-state outputs | 16 buffered outputs with 5 V tolerant structure and IOFF protection |
| VCC (pins 7, 18, 31, 42) | Supply voltage | Four distributed VCC pins minimize supply noise and improve decoupling effectiveness |
| GND (pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins reduce ground bounce and enhance signal integrity in high-speed switching |
Key Features
| Feature | Design Value |
|---|---|
| 5 V tolerant I/O | Supports interoperability with legacy 5 V logic while powered from 1.2–3.6 V supplies |
| Integrated bus hold | Eliminates external pull-up/pull-down resistors on all 16 data inputs, reducing BOM count and PCB area |
| IOFF partial power-down | Prevents damaging back-current when VCC is off but I/O lines remain active at 5 V |
| Schmitt-trigger inputs | Accepts slow-rising signals down to 10 ns/V slew rate, easing timing margin in noisy environments |
| MULTIBYTE flow-through pinout | Minimizes trace length and crosstalk in dense PCB layouts via logical D/Q pairing per byte |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit transparent latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVCH16373A | TI part with identical pinout, same 1.2–3.6 V VCC range and 5 V tolerant I/O, but lacks bus hold circuitry | Requires external pull-up resistors on unused D-inputs; unsuitable where BOM reduction is critical | Select when cost sensitivity outweighs bus hold benefit and external biasing is acceptable |
| 74LVC16373ADL,118 | Nexperia variant without bus hold; otherwise identical electrical specs and packaging | Lower static current draw (no bus hold leakage), but requires external termination for unused inputs | Choose for ultra-low standby power designs where all inputs are actively driven |
Compared with SN74LVCH16373A and 74LVC16373ADL,118, the 74LVCH16373ADL,118 uniquely integrates bus hold-reducing component count and layout complexity-while maintaining full pin and functional compatibility with both alternatives in non-bus-hold configurations.

FAQ
Does 74LVCH16373ADL,118 support hot-swap operation?
Yes. Its IOFF circuitry actively disables outputs when VCC = 0 V, preventing backflow current from live 5 V buses into the unpowered device-enabling safe insertion/removal in powered-backplane systems like modular PLC racks.
What is the maximum clock/data rate supported by this latch?
The device does not use a clock; it is edge-triggered only on LE transitions. With tpd ≤ 4.4 ns and tsu/th ≥ 2.0 ns/0.9 ns at 3.3 V, it reliably captures data on buses operating up to ~100 MHz toggle rate when used with appropriate setup/hold margins.
Can unused data inputs be left floating?
Yes. All 16 D-inputs feature integrated bus hold circuitry that maintains last-valid logic state without external resistors-eliminating risk of metastability or increased power consumption from floating inputs.
How does the dual-latch architecture improve system design?
Dual independent 8-bit sections (1LE/1OE and 2LE/2OE) allow simultaneous but isolated latching of address vs. data, high-byte vs. low-byte, or sensor vs. actuator channels-reducing timing conflicts and simplifying control logic in multi-bus architectures.
