Product details
Overview
74ALVC573PW,118 from Nexperia is an octal D-type transparent latch with 3-state outputs, designed for data latching and bus isolation in low-voltage digital systems. It operates across 1.65 V to 3.6 V, features independent latch enable (LE) and output enable (OE) controls, supports -40 °C to +125 °C operation, and includes IOFF circuitry for partial power-down protection. It is used in address/data bus buffering in microcontroller peripherals and FPGA I/O expansion.
For engineers reviewing the 74ALVC573PW,118 datasheet, 74ALVC573PW,118 pinout, 74ALVC573PW,118 application, or 74ALVC573PW,118 equivalent, key selection criteria include 3-state timing (tpd ≤ 3.8 ns at 3.3 V), IOFF-enabled power-down safety, Schmitt-trigger input tolerance, latch transparency behavior, and TSSOP20 package compatibility with high-density PCB layouts.
Technical Context
This device implements eight independent D-type latches with synchronous transparent mode (LE HIGH) and edge-triggered capture (LE HIGH-to-LOW transition). Each latch stores data one setup time before LE falls, and outputs remain stable until OE asserts to disable them into high-impedance state - independent of latch state.
Schmitt-trigger inputs tolerate slow-rising/falling signals up to 10 ns/V slew rate (at VCC ≥ 2.7 V), while IOFF circuitry actively disables outputs when VCC = 0 V, blocking backflow current during hot-swap or partial power-down sequences in multi-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 3.6 V - enables direct interfacing with 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Propagation Delay (D→Q) | ≤ 3.8 ns at VCC = 3.3 V - ensures sub-4 ns timing margin for 200+ MHz bus handshaking in high-speed control paths. |
| IOFF Leakage Current | ±80 μA max at VCC = 0 V - guarantees safe bidirectional signal isolation during power sequencing in mixed-supply systems. |
| Input Voltage Tolerance | Inputs tolerant to 3.6 V regardless of VCC - allows connection to higher-voltage buses without external clamping diodes. |
| Operating Temperature | -40 °C to +125 °C - qualified for industrial and extended-temperature embedded applications including motor control and power management. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets JEDEC JS-001/JS-002 Class 2/C3 for robust handling in automated assembly and field environments. |
| Power Dissipation Capacitance | CPD = 37 pF (outputs active) - enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal budgeting. |
Pinout & Package
TSSOP20 plastic thin shrink small outline package (SOT360-1); 20-terminal surface-mount package with 0.65 mm pitch, 4.4 mm body width, and 0.8–1.1 mm height - optimized for high-density routing and thermal performance in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output Enable (active LOW) | Asserting LOW enables Q0–Q7 outputs; HIGH forces all outputs into high-impedance state without affecting internal latch states. |
| 2–9 (D0–D7) | Data Inputs | Asynchronous inputs sampled when LE = HIGH; Schmitt-triggered for noise immunity on slow or noisy control lines. |
| 11 (LE) | Latch Enable (active HIGH) | When HIGH, latches are transparent; falling edge captures Dn values into storage registers for subsequent readout. |
| 12–19 (Q0–Q7) | 3-State Outputs | Driven HIGH/LOW when OE = LOW and latched value is valid; tri-stated when OE = HIGH - enables shared bus arbitration. |
| 10 (GND) | Ground Reference | Primary 0 V reference for all input thresholds, output drive, and internal logic - must be low-impedance for noise-free operation. |
| 20 (VCC) | Supply Voltage | Single supply rail powering all logic and output drivers; IOFF remains functional even when VCC = 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–3.6 V) | Eliminates need for voltage translation between 1.8 V FPGAs and 3.3 V peripheral buses in mixed-voltage systems. |
| IOFF partial power-down | Prevents destructive back-current flow when VCC is off but I/O lines remain energized - critical for hot-plug and modular subsystems. |
| Schmitt-trigger inputs | Enables reliable capture of slow-switching control signals (e.g., reset, enable, or configuration lines) without external RC filtering. |
| 8-bit transparent latch + 3-state | Supports simultaneous data capture and bus release in single-cycle operations - ideal for address latching in microprocessor memory interfaces. |
| JESD8-compliant interface | Guarantees interoperability with TTL-level sources and CMOS loads across all supported VCC ranges per JEDEC standards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal transparent latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC573APWR | TI part with identical pinout and function but wider VCC range (1.65–3.6 V), same tpd (3.8 ns), and lower IOFF leakage (±10 μA). | Preferred in TI-centric BOMs; slightly better power-down isolation but requires separate qualification for automotive-grade use. | Select when leveraging TI's broad support ecosystem or requiring tighter IOFF specs in ultra-low-power standby modes. |
| 74LVC573AD,118 | Nexperia SO20 variant (SOT163-1) - same electrical specs but larger 7.5 mm body width and higher thermal resistance (12.3 mW/K derating above 109 °C). | Better suited for through-hole prototyping or legacy board rework where TSSOP footprint isn't available. | Choose only if mechanical constraints prevent TSSOP use - otherwise 74ALVC573PW,118 offers superior density and thermal performance. |
Compared with SN74LVC573APWR, the 74ALVC573PW,118 offers identical functionality with higher ESD robustness (HBM >2000 V vs. 2000 V typical) and broader temperature qualification (-40 °C to +125 °C fully specified), while the 74LVC573AD,118 trades package compactness for easier manual assembly and legacy compatibility.

FAQ
Does 74ALVC573PW,118 support hot-swap operation?
Yes - its IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±80 μA maximum. This prevents damage during live insertion/removal in modular backplanes or hot-pluggable modules, provided OE is held HIGH during power-off sequencing.
Can 74ALVC573PW,118 interface directly with 5 V TTL logic?
No - inputs tolerate up to 3.6 V absolute maximum, and VCC must be within 1.65–3.6 V. Direct connection to 5 V TTL violates VI limits and risks latch damage. Use a level translator like TXB0108 or resistive divider network for safe interfacing.
What is the minimum pulse width required on LE for reliable latching?
The minimum LE HIGH pulse width is 3.3 ns across all VCC ranges (1.65–3.6 V). This ensures sufficient time for internal metastability resolution and data capture - critical for synchronizing with fast clock edges in high-speed control logic.
How does Schmitt-trigger input action benefit system design?
Schmitt-trigger inputs provide hysteresis (typically 0.3–0.5 V), allowing reliable recognition of slow-rising/falling signals (e.g., from mechanical switches or RC-filtered control lines) without oscillation or multiple triggering - eliminating need for external debouncing circuits.
