Product details
Overview
74AVC16373DGG,118 from Nexperia is a 16-bit D-type transparent latch with dual 8-bit sections, 3-state true outputs, 1.2 V to 3.6 V supply operation, 3.6 V I/O tolerance, and Dynamic Controlled Output (DCO) circuitry for noise reduction without speed penalty. It serves as a bus interface latch in high-speed digital systems requiring level translation and transient-robust output drive.
For engineers reviewing the 74AVC16373DGG,118 datasheet, 74AVC16373DGG,118 pinout, 74AVC16373DGG,118 application, or 74AVC16373DGG,118 equivalent, key selection criteria include propagation delay down to 0.7 ns at 3.3 V, dual independent latch/enable control per 8-bit section, TSSOP48 package thermal and routing constraints, and DCO-enabled termination line drive capability.
Technical Context
The device implements two independent 8-bit transparent latches, each with dedicated latch enable (LE) and output enable (OE) inputs - enabling selective capture and tri-state control of data buses. Its CMOS architecture supports mixed-voltage system interfacing via 3.6 V tolerant I/Os while operating from as low as 1.2 V.
Dynamic Controlled Output (DCO) circuitry actively modulates output impedance during signal transitions to suppress simultaneous switching noise (SSN), maintaining signal integrity on stubbed or unterminated lines without increasing propagation delay. The design includes multiple low-inductance VCC/GND pairs to minimize ground bounce in dense PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - Enables direct interfacing between 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Propagation Delay (tpd) | 0.7 ns (max) at VCC = 3.3 V - Supports >350 MHz bus operation with tight timing margins in high-speed data paths. |
| I/O Voltage Tolerance | Up to 3.6 V - Allows safe connection to 3.3 V buses even when powered from lower supply rails (e.g., 1.8 V core). |
| Output Drive Strength | ±12 mA at VCC = 3.0 V - Sufficient to drive standard 50 Ω transmission lines or 10–15 pF loads with controlled edge rates. |
| Power Dissipation Capacitance (CPD) | 34 pF (enabled), 1 pF (disabled) - Enables accurate dynamic power estimation for thermal and battery-life modeling. |
| Set-up/Hold Time | tsu = 0.8 ns, th = 1.0 ns at VCC = 3.3 V - Permits reliable latching of fast DDR-style data strobes with minimal timing margin overhead. |
| Operating Temperature | −40 °C to +85 °C - Qualified for industrial-grade embedded control, networking, and test equipment environments. |
Pinout & Package
TSSOP48 (SOT362-1) package: plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm lead pitch, exposed pad not present. Designed for fine-pitch surface-mount assembly with moderate thermal dissipation (Ptot = 500 mW at 85 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1D0–1D7, 2D0–2D7 (pins 47,46,44,43,41,40,38,37 / 36,35,33,32,30,29,27,26) | Data inputs | Two independent 8-bit parallel input groups; accept asynchronous data for transparent latching. |
| 1Q0–1Q7, 2Q0–2Q7 (pins 2,3,5,6,8,9,11,12 / 13,14,16,17,19,20,22,23) | Data outputs | True 3-state outputs per section; driven only when corresponding OE is LOW and LE is HIGH. |
| 1LE, 2LE (pins 48, 25) | Latch enable | Active-HIGH per section - captures input data on rising edge and holds until next LE assertion. |
| 1OE, 2OE (pins 1, 24) | Output enable | Active-LOW per section - places associated Q outputs in high-impedance state independently of latch state. |
| VCC (pins 7,18,31,42) | Supply voltage | Four distributed power pins reduce IR drop and improve PSRR across wide frequency range. |
| GND (pins 4,10,15,21,28,34,39,45) | Ground | Eight ground pins minimize ground bounce and provide low-inductance return paths for all I/Os. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Controlled Output (DCO) | Real-time output impedance modulation during transitions reduces SSN by >40% vs. fixed-drive latches, preserving signal fidelity on unterminated traces. |
| Live Insertion Support | Pull-up on nOE ensures outputs remain high-Z during hot-plug events, preventing bus contention and backdrive damage. |
| JEDEC Compliance | Fully compliant with JESD8-7 (1.2–1.95 V), JESD8-5 (1.8–2.7 V), and JESD8-1A (2.7–3.6 V) - guarantees interoperability across multi-vendor 1.8 V/2.5 V/3.3 V systems. |
| Low Power Consumption | ICC ≤ 40 μA at VCC = 3.3 V and Tamb = 25 °C - enables use in always-on subsystems with strict quiescent current budgets. |
| Bus-Oriented Architecture | Dual 8-bit sections with independent LE/OE allow partial bus isolation - e.g., latch address while holding data, or enable only one memory bank's data path. |
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 |
|---|---|---|---|
| SN74AVC16373DGGR | Same logic function and pinout; TI version uses different process node - slightly higher ICC (60 μA typical) and slower tpd (1.1 ns max at 3.3 V). | Less suitable for ultra-low-power or <1 ns timing-critical designs; compatible in legacy TI-based designs. | Select if sourcing from TI-authorized channels or maintaining existing BOM continuity with TI references. |
| 74LVC16373ADGG,118 | Lower VCC range (1.65–3.6 V); no DCO; higher VOL (0.55 V @ 8 mA) and longer tpd (2.8 ns max at 3.3 V). | Acceptable for cost-sensitive industrial applications where SSN is mitigated externally; lacks live insertion robustness. | Choose when budget constraints outweigh noise performance needs and full 1.2 V compatibility is unnecessary. |

FAQ
What is the minimum recommended VCC for guaranteed operation?
The 74AVC16373DGG,118 is specified for operation down to 1.2 V per JEDEC JESD8-7. At this rail, static parameters (VIH/VIL) and dynamic timing (tpd, tsu) remain within datasheet limits across −40 °C to +85 °C. Operation below 1.2 V is not characterized and may result in metastability or increased ICC.
How should the nOE pins be handled during power-up?
To ensure outputs remain in high-impedance state during power-up/power-down, each nOE pin (pins 1 and 24) must be tied to VCC via a pull-up resistor (typically 10 kΩ). This prevents bus contention when VCC ramps before control logic stabilizes - a requirement explicitly stated in the datasheet for live insertion compliance.
Does the DCO feature require external configuration?
No. Dynamic Controlled Output (DCO) is fully internal and automatic - it activates during signal transitions without external bias, registers, or enable signals. The circuit senses output slew rate and adjusts drive strength in real time to suppress ringing and overshoot on unterminated lines.
Can both 8-bit sections operate at different supply voltages?
No. The device has a single VCC rail (pins 7,18,31,42) shared across all logic and I/O. While I/Os tolerate up to 3.6 V regardless of VCC, the internal latch circuitry operates only at the applied VCC. Independent voltage domains per section are not supported.
