Product details
Overview
74AVC16244DGG,118 from Nexperia is a 16-bit non-inverting buffer/line driver with 3-state outputs, designed for voltage-level translation and bus isolation in high-speed digital systems operating from 1.2 V to 3.6 V. It supports four independent 4-bit channels (1A–1Y, 2A–2Y, 3A–3Y, 4A–4Y), features Dynamic Controlled Output (DCO) for noise reduction, tolerates 3.6 V inputs at any supply down to 1.2 V, and delivers propagation delay as low as 0.5 ns at 3.3 V - enabling use in DDR memory interfaces and FPGA I/O expansion.
For engineers reviewing the 74AVC16244DGG,118 datasheet, 74AVC16244DGG,118 pinout, 74AVC16244DGG,118 application, or 74AVC16244DGG,118 equivalent, key selection criteria include 3.6 V input tolerance across 1.2–3.6 V VCC, sub-2 ns enable/disable timing, DCO-enabled transient noise suppression, and TSSOP48 package compatibility with high-density PCB layouts.
Technical Context
The device implements four independent 4-bit non-inverting buffers, each controlled by an active-low output enable (nOE) input. Each channel's 3-state output transitions between driven HIGH/LOW and high-impedance OFF-state based on nOE logic level, with built-in Live Insertion support via pull-up on nOE.
Dynamic Controlled Output (DCO) circuitry modulates output impedance during signal transitions to suppress ringing and ground bounce without sacrificing speed; this is confirmed by Figure 4's VOH/VOL vs. IO curves across 1.8 V, 2.5 V, and 3.3 V supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.2 V to 3.6 V - enables single-supply operation across LVCMOS, LVTTL, and mixed-voltage system interfaces. |
| Input Tolerance | Up to 3.6 V - allows interfacing with higher-voltage peripherals while powered from 1.2 V or 1.8 V rails. |
| tpd (Max) | 1.7 ns at VCC = 3.0–3.6 V - ensures minimal signal skew in high-speed data paths such as memory address/data buses. |
| ten / tdis (Max) | 3.5 ns / 3.5 ns at VCC = 3.0–3.6 V - supports fast bus arbitration and dynamic channel enable/disable in multiplexed systems. |
| IOZ (Max) | 10 μA at VCC = 3.0–3.6 V - guarantees low leakage in 3-state mode, critical for maintaining signal integrity on shared buses. |
| CI (Typ) | 5.0 pF - minimizes capacitive loading on driving sources, preserving edge rates in fan-out-heavy configurations. |
| DCO Support | Yes - dynamically adjusts output drive strength during transitions to reduce simultaneous switching noise (SSN) without degrading rise/fall times. |
Pinout & Package
TSSOP48 (SOT362-1) package: plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm lead pitch, with eight GND pins (pins 4, 10, 15, 21, 28, 34, 39, 45) and four VCC pins (7, 18, 31, 42) for low-inductance power delivery and noise suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE, 3OE, 4OE (pins 1, 48, 25, 24) | Active-low output enable | Each controls one 4-bit channel's 3-state output; HIGH forces high-impedance OFF-state for bus isolation. |
| 1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 (pins 47,46,44,43,41,40,38,37,36,35,33,32,30,29,27,26) | Data inputs | 16 total inputs grouped into four 4-bit banks; accept 3.6 V-tolerant signals regardless of VCC. |
| 1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3 (pins 2,3,5,6,8,9,11,12,13,14,16,17,19,20,22,23) | Data outputs | 16 buffered, non-inverting outputs with DCO; drive loads up to ±12 mA at 3.3 V. |
| GND (pins 4,10,15,21,28,34,39,45) | Ground reference | Eight distributed ground pins minimize ground bounce and improve signal integrity in high-speed switching. |
| VCC (pins 7,18,31,42) | Supply voltage | Four decoupled VCC pins reduce supply inductance and stabilize core logic during transient current demands. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Controlled Output (DCO) | Adjusts output impedance in real time during signal transitions to suppress overshoot/ringing while maintaining <1.7 ns propagation delay. |
| 3.6 V Input Tolerance | Accepts 3.6 V logic inputs even when VCC = 1.2 V - eliminates need for external level shifters in mixed-voltage systems. |
| Live Insertion Support | High-impedance default state during power-up/down is ensured by tying nOE to VCC via pull-up resistor - prevents bus contention in hot-swap applications. |
| Low Inductance Pin Layout | Eight GND and four VCC pins interleaved across the package reduce power supply noise and ground bounce in high-frequency operation. |
| 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) standards for interoperability with industry-standard logic families. |
Applications
| DDR Memory Interface | FPGA I/O Expansion |
|---|---|
Use Scenario: Driving address and control lines between DDR3/DDR4 controller and memory modules with mismatched voltage domains (e.g., 1.8 V controller to 3.3 V legacy DIMM).

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC16244DGGR (TI) | Same functional spec, identical pinout, but rated only to +70 °C ambient and lacks DCO circuitry per datasheet. | Not suitable for industrial temperature range (-40 °C to +85 °C) or noise-sensitive applications requiring DCO-based transient suppression. | Select only if operating within commercial temp range and SSN mitigation is handled externally. |
| 74LVC16244APAG (ON Semiconductor) | 3.3 V max VCC, no 3.6 V input tolerance; static output drive only (no DCO); 16 ns max tpd at 3.3 V. | Cannot replace in mixed-voltage designs requiring 1.2 V–3.6 V operation or sub-2 ns timing; unsuitable for DDR/FPGA interfaces demanding tight skew control. | Consider only for cost-sensitive, low-speed 3.3 V-only systems where DCO and wide VCC are unnecessary. |

FAQ
What is the maximum input voltage the 74AVC16244DGG,118 can safely accept?
The device accepts input voltages up to 3.6 V regardless of VCC level, verified per Table 4 (Limiting Values) and Table 5 (Recommended Operating Conditions). This 3.6 V tolerance applies across the full 1.2 V–3.6 V supply range and is enabled by internal clamping structures - allowing direct connection to 3.3 V peripherals even when powered from 1.2 V or 1.8 V rails without external protection.
Does the 74AVC16244DGG,118 require external pull-up resistors on its OE pins?
Yes - to ensure high-impedance outputs during power-up or power-down (Live Insertion), each nOE pin must be tied to VCC via an external pull-up resistor. The datasheet specifies this as mandatory for safe bus operation; failure to implement pull-ups risks output contention and potential damage during supply ramping.
How does Dynamic Controlled Output (DCO) improve signal integrity?
DCO dynamically lowers output impedance during signal transitions to dampen ringing and overshoot caused by transmission line effects, then restores full drive strength post-transition - all without increasing propagation delay. This is confirmed by Figure 4's VOH/VOL vs. IO curves showing reduced current swing magnitude at intermediate voltages, directly suppressing simultaneous switching noise (SSN) in high-fanout buses.
Can the 74AVC16244DGG,118 be used in automotive applications?
No - the device is not AEC-Q200 qualified or automotive-grade rated. The datasheet explicitly states in Section 14.4 that "Unless this data sheet expressly states that this specific Nexperia product is automotive qualified, the product is not suitable for automotive use." It is intended for industrial, computing, and communications applications operating from −40 °C to +85 °C.
