Product details

Overview

74AVC16245DGG,112 from Nexperia is a 16-bit non-inverting 3-state bus transceiver with dual direction control (1DIR/2DIR) and dual output enable (1OE/2OE), operating from 1.2 V to 3.6 V supply. It supports bidirectional data flow between two 8-bit buses or one unified 16-bit bus, features Dynamic Controlled Output (DCO) for noise reduction, and delivers propagation delay as low as 0.5 ns at 3.3 V in high-speed memory and logic interface applications.

For engineers reviewing the 74AVC16245DGG,112 datasheet, 74AVC16245DGG,112 pinout, 74AVC16245DGG,112 application, or 74AVC16245DGG,112 equivalent, key selection criteria include voltage tolerance (3.6 V I/O), ultra-low propagation delay across supply range, DCO-enabled signal integrity, TSSOP48 package thermal and routing constraints, and cascading capability via independent OE/DIR controls.

Technical Context

This transceiver implements dual independent 8-bit channels, each with dedicated direction (nDIR) and output enable (nOE) inputs, enabling flexible bus isolation and directional control without external logic. Its CMOS design ensures compatibility with JEDEC standards JESD8-7 (1.2–1.95 V), JESD8-5 (1.8–2.7 V), and JESD8-1A (2.7–3.6 V).

The Dynamic Controlled Output (DCO) circuit dynamically adjusts output impedance during signal transitions to suppress ringing and ground bounce while preserving timing performance. Low-inductance multiple VCC/GND pins (4 VCC, 8 GND) further reduce noise and improve power integrity in dense PCB layouts.

Key Specifications

Pinout & Package

TSSOP48 plastic thin shrink small outline package (SOT362-1), 48-pin, body width 6.1 mm, with 4 VCC and 8 GND pins for low-noise power distribution.

Pin/Terminal	Circuit Role	Design Meaning
1DIR, 2DIR	Direction control input	Active-HIGH logic selects data flow direction per 8-bit channel (A→B or B→A).
1OE, 2OE	Output enable input	Active-LOW control enables/disables outputs independently-critical for bus arbitration and live insertion.
1A0–1A7, 2A0–2A7	Data I/O port A	First and second 8-bit bidirectional bus ports connected to local subsystem (e.g., CPU data bus).
1B0–1B7, 2B0–2B7	Data I/O port B	Corresponding 8-bit bidirectional bus ports connected to peripheral or memory subsystem.
VCC (pins 7, 18, 31, 42)	Supply voltage	Multiple distributed VCC pins minimize IR drop and improve transient response under fast switching.
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 operation.

Key Features

Feature	Design Value
Dynamic Controlled Output (DCO)	Real-time output impedance adjustment suppresses overshoot/ringing without sacrificing speed-verified in Figure 4/5 waveforms.
Live Insertion Support	Pull-up nOE to VCC ensures high-impedance state during hot-plug events-prevents bus contention on backplane or modular systems.
JEDEC Compliance	Fully compliant with JESD8-7, JESD8-5, and JESD8-1A voltage standards-guarantees interoperability across 1.2 V to 3.6 V logic families.
Low Ground Bounce	8 GND pins + low-inductance layout reduce ΔI/Δt-induced noise-measured in static/dynamic characterization (Tables 6–7).
Ultra-Fast Enable/Disable	Enable time (ten) as low as 0.7 ns and disable time (tdis) as low as 1.2 ns at 3.3 V-enables precise timing control in burst-mode transfers.

Applications

Memory Interface Buffering

Processor-to-Peripheral Data Bridge

Use Scenario: Bidirectional data transfer between a 16-bit microcontroller and external SRAM or Flash memory.

IC Role / Device Role / Timing Role: Acts as voltage-tolerant, low-latency bus transceiver managing address/data multiplexing and direction control synchronized to memory read/write strobes.

Use Value: Enables direct connection between 1.8 V MCU and 3.3 V memory without level shifters, while DCO minimizes signal reflections on long traces.

Use Scenario: Interfacing an FPGA I/O bank (1.2 V/1.8 V) with legacy 3.3 V peripheral ICs (e.g., UART, SPI flash, GPIO expanders).

IC Role / Device Role / Timing Role: Provides isolated, direction-controlled data path with independent OE/DIR per 8-bit lane-supports partial bus updates and protocol handshaking.

Use Value: Eliminates need for discrete MOSFET-based level translators; 0.5 ns propagation delay preserves setup/hold margins in high-frequency peripheral access.

Hot-Swappable Backplane Module

Industrial PLC I/O Expansion

Use Scenario: Data exchange between a main controller card and field-replaceable I/O module in a modular automation rack.

IC Role / Device Role / Timing Role: Transceiver enforces bus isolation during module insertion/removal via pull-up nOE; DCO maintains signal fidelity across variable trace lengths.

Use Value: Live insertion support prevents system downtime; 8 GND pins suppress noise in electrically noisy industrial environments.

Use Scenario: Extending digital input/output capacity of a programmable logic controller using standardized 16-bit parallel expansion headers.

IC Role / Device Role / Timing Role: Buffers and isolates PLC's internal bus from external sensor/actuator modules, with direction control matching scan-cycle data flow.

Use Value: −40 °C to +85 °C rating ensures reliability in uncontrolled cabinet environments; 3.6 V I/O tolerance accommodates legacy 5 V-tolerant sensors via resistive dividers.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74AVC16245DGGR	Same electrical specs and pinout; RoHS-compliant, green packaging (lead-free, halogen-free); identical TSSOP48 footprint.	No functional difference-designed for same industrial/computing use cases requiring 1.2–3.6 V operation.	Select when lead-free compliance or extended environmental certification (e.g., IPC-J-STD-020) is required.
74LVC16245APAG	Wider VCC range (1.65–3.6 V); higher ICC (max 40 µA vs. 20 µA at 2.7 V); no DCO circuitry-higher EMI risk at high edge rates.	Lacks DCO and live-insertion optimization; less suitable for high-speed or hot-swap-critical designs.	Choose only if cost sensitivity outweighs signal integrity requirements and supply is ≥1.65 V.

Compared with SN74AVC16245DGGR, the 74AVC16245DGG,112 offers identical functionality but differs in tape-and-reel packaging and date-code traceability; versus 74LVC16245APAG, it provides superior noise suppression, lower propagation delay, and broader voltage support-making it preferred for next-generation low-voltage, high-integrity bus architectures.

FAQ

What is the minimum supply voltage for guaranteed operation of the 74AVC16245DGG,112?

The device is fully specified down to 1.2 V supply voltage per JEDEC JESD8-7, with propagation delay, drive strength, and logic thresholds validated across that range. At 1.2 V, tpd is 2.8 ns (typical), VIH is referenced to VCC, and IO remains ±100 µA-enabling direct integration with advanced low-voltage SoCs and FPGAs.

How does the Dynamic Controlled Output (DCO) function improve signal integrity?

DCO dynamically lowers output impedance during signal transitions to match line impedance, reducing reflections and overshoot without increasing propagation delay. This behavior is confirmed in Figures 4 and 5 of the datasheet, where VOH/VOL curves show controlled slew under varying load conditions-critical for maintaining eye diagram margin in 100+ MHz parallel buses.

Can the 74AVC16245DGG,112 be used as two independent 8-bit transceivers?

Yes-pins 1DIR/1OE control the first 8-bit channel (1A0–1A7 ↔ 1B0–1B7), while 2DIR/2OE manage the second (2A0–2A7 ↔ 2B0–2B7). Each channel operates independently in direction, enable, and timing, allowing simultaneous bidirectional transfers or isolated bus segments in multi-master systems.

What is the recommended approach for handling unused pins?

Unused nOE inputs must be tied HIGH (e.g., via 10 kΩ pull-up to VCC) to ensure outputs remain in high-impedance state; unused nDIR inputs should be tied HIGH or LOW depending on desired default direction. All unused I/O pins (A/B) may be left floating only if permanently disabled by nOE-otherwise, terminate to VCC or GND to prevent oscillation and EMI.
