Product details
Overview
74AVC16245DGVRG4 from Texas Instruments is a 16-bit dual-octal noninverting bus transceiver with 3-state outputs, designed for asynchronous bidirectional data communication between mixed-voltage buses (1.2 V to 3.6 V). It features Dynamic Output Control (DOC™), Ioff partial-power-down support, and ±24 mA dynamic drive capability at 2.5 V - enabling low-noise, high-speed interconnect in FPGA-to-ASIC or memory interface applications.
For engineers reviewing the 74AVC16245DGVRG4 datasheet, 74AVC16245DGVRG4 pinout, 74AVC16245DGVRG4 application, or 74AVC16245DGVRG4 equivalent, this device delivers verified 1.7 ns max propagation delay at 3.3 V, overvoltage-tolerant I/Os up to 4.6 V, and guaranteed operation from –40°C to 85°C in TVSOP-48 packaging.
Technical Context
The 74AVC16245DGVRG4 implements a dual 8-bit transceiver architecture with independent DIR and OE controls per octal section, supporting A→B or B→A data flow under logic-level direction control. Its DOC™ circuit dynamically modulates output impedance during signal transitions - lowering it initially for fast edge drive, then raising it to suppress switching noise without sacrificing speed.
It operates across 1.2 V–3.6 V VCC with rail-to-rail input thresholds (VIH/VIL scaling with VCC), supports Ioff protection to prevent backflow during partial power-down, and meets JESD 78 latch-up immunity (>250 mA) and JESD 22 ESD ratings (2000-V HBM, 200-V MM).

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC16245DGGRG4 | TSSOP-48 (DGG) package; 1.2 mm height vs. DGV's 1.0 mm; θJA = 70°C/W vs. 58°C/W | Better thermal performance in high-density layouts; slightly larger footprint (12.5 mm × 6.1 mm vs. 12.5 mm × 6.1 mm, but thicker) | Select DGGRG4 for improved heat dissipation in sustained 24 mA drive scenarios; DGV preferred for ultra-thin assemblies. |
| SN74LVC16245ADGGR | Lower drive (±24 mA only at 3.3 V); no DOC™; VIH/VIL fixed thresholds; 1.65–3.6 V VCC only | Lacks mixed-voltage flexibility and noise suppression; requires external level translation below 1.65 V | Choose LVC variant only if operating strictly at 3.3 V and cost sensitivity outweighs noise/EMI requirements. |

FAQ
What voltage levels does the 74AVC16245DGVRG4 support for VCC and I/O operation?
The 74AVC16245DGVRG4 operates with VCC from 1.2 V to 3.6 V and supports I/O voltages from –0.5 V to 4.6 V regardless of VCC level. This allows safe interfacing between 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V domains without external level shifters. The 74AVC16245DGVRG4 maintains full functionality and specified timing across this entire range, including data retention at 1.2 V.
How does the Dynamic Output Control (DOC™) circuit in the 74AVC16245DGVRG4 reduce noise?
The DOC™ circuit in the 74AVC16245DGVRG4 dynamically adjusts output impedance during signal transitions: it lowers impedance initially to deliver strong edge drive, then raises it mid-transition to suppress ringing and crosstalk. This achieves ±24 mA effective drive at 2.5 V while cutting simultaneous switching noise by up to 50% versus fixed-drive transceivers - directly improving signal integrity on dense 16-bit buses. The 74AVC16245DGVRG4 implements this without increasing propagation delay beyond 1.7 ns.
Can the 74AVC16245DGVRG4 be used in partial-power-down systems?
Yes - the 74AVC16245DGVRG4 includes Ioff circuitry that disables outputs and limits leakage to ±10 µA when VCC = 0 V, preventing damaging current backflow during power sequencing or hot-swap events. This makes the 74AVC16245DGVRG4 suitable for modular backplanes and field-upgradeable systems where subsystems power up/down independently while sharing common data buses.
What is the pin count and package type of the 74AVC16245DGVRG4?
The 74AVC16245DGVRG4 uses a 48-pin TVSOP (Thin Very Small Outline Package) with designation DGV. Its dimensions are 12.5 mm × 6.1 mm × 1.0 mm maximum height, 0.4 mm lead pitch, and JEDEC MO-153 compliance. Pin 1 is located at the top-left corner (Q1 quadrant), identified by a beveled edge. The 74AVC16245DGVRG4 has eight VCC and nine GND pins distributed for optimal power integrity.
Does the 74AVC16245DGVRG4 support both 16-bit and dual 8-bit operation?
Yes - the 74AVC16245DGVRG4 is architecturally dual 8-bit: DIR and OE inputs are provided per octal section (1DIR/1OE and 2DIR/2OE), allowing independent control of two 8-bit data paths. It can operate as a single 16-bit transceiver (with shared DIR/OE) or two autonomous 8-bit transceivers (with separate DIR/OE signals), giving designers flexibility in bus partitioning and timing management. This dual-mode capability is intrinsic to the 74AVC16245DGVRG4's logic diagram and function table.
