Product details
Overview
74LVC16245ADGG,112 from Nexperia is a 16-bit 3-state bus transceiver with dual direction control (1DIR/2DIR) and dual output enables (1OE/2OE), operating from 1.2 V to 3.6 V supply while accepting 5.5 V-tolerant inputs. It supports bidirectional data flow across two independent 8-bit ports or as a unified 16-bit path, enabling level translation between 3.3 V and 5 V domains in memory expansion and FPGA I/O buffering applications.
For engineers reviewing the 74LVC16245ADGG,112 datasheet, 74LVC16245ADGG,112 pinout, 74LVC16245ADGG,112 application, or 74LVC16245ADGG,112 equivalent, key selection criteria include its IOFF partial power-down protection, Schmitt-trigger input noise immunity, 1.2 V minimum VCC operation, and TSSOP48 package compatibility with high-density PCB layouts.
Technical Context
This device implements a dual-8-bit flow-through architecture with separate direction and enable controls per byte lane, allowing independent bidirectional data routing without internal bus contention. Its CMOS design delivers low static current (≤80 μA at 3.6 V) and dynamic power dissipation governed by CPD = 18.5 pF at 3.3 V.
The IOFF circuit actively disables outputs during power-down to block backflow current, while Schmitt-trigger inputs tolerate slow-rising signals (Δt/ΔV down to 20 ns/V at 1.2 V). Bus hold functionality is absent in the LVC variant (present only in LVCH), distinguishing its input behavior from pin-compatible alternatives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.2 V to 3.6 V - Enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic families. |
| Input Voltage Tolerance | Up to 5.5 V - Allows safe connection to 5 V sources without external clamping in mixed-voltage systems. |
| Propagation Delay | 1.0 ns (min) to 4.5 ns (max) at 3.3 V - Supports >200 MHz data rates in point-to-point bus configurations. |
| IOFF Leakage | ±10 μA max at VCC = 0 V - Prevents damaging back-current during hot-swap or partial power-down sequences. |
| Operating Temperature | –40 °C to +125 °C - Qualified for industrial and extended-temperature embedded control environments. |
| ESD Rating | HBM >2000 V, CDM >1000 V - Meets JEDEC JS-001/JS-002 Class 2/C3 for robust handling in manufacturing. |
Pinout & Package
TSSOP48 package (SOT362-1), 48-pin plastic thin shrink small outline, 6.1 mm body width, 0.5 mm lead pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input (active HIGH) | Determines data flow direction per 8-bit port: HIGH = A→B, LOW = B→A. |
| 1OE, 2OE | Output enable input (active LOW) | Asserting LOW enables corresponding 8-bit port outputs; HIGH forces 3-state high-impedance. |
| 1A0–1A7, 2A0–2A7 | Data I/O port A (side A) | First and second 8-bit bidirectional data terminals connected to one system bus segment. |
| 1B0–1B7, 2B0–2B7 | Data I/O port B (side B) | First and second 8-bit bidirectional data terminals connected to second system bus segment. |
| VCC | Supply voltage | Single 1.2–3.6 V rail powers all logic and I/O; no separate I/O voltage required. |
| GND | Ground reference | Eight dedicated ground pins minimize ground bounce and improve signal integrity in high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 8-bit control | Separate 1DIR/1OE and 2DIR/2OE allow asynchronous bidirectional data transfer on two lanes. |
| 5.5 V-tolerant inputs | Eliminates need for external level-shifting components when interfacing with legacy 5 V peripherals. |
| IOFF partial power-down | Automatically disables outputs and blocks reverse current when VCC = 0 V, supporting hot-plug capability. |
| Schmitt-trigger inputs | Provides ≥0.3 V hysteresis to reject noise on slow-rising/falling signals (e.g., mechanical switches, long traces). |
| MULTIBYTE flow-through pinout | Alternating A/B pin arrangement reduces crosstalk and simplifies PCB routing in parallel bus layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bidirectional bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVCH16245ADGG | Includes bus hold on all data inputs (IBHL/IBHH ≈ ±75 μA); identical pinout and electrical specs otherwise. | Eliminates need for external pull-ups on unused data lines; preferred in systems with floating I/O during reset or standby. | Select when deterministic input state retention is required without board-level resistors. |
| SN74LVC16245ADGGR | Texas Instruments variant in same TSSOP48 package; VCC range 1.65–3.6 V (no 1.2 V support); slightly higher tpd (5.5 ns max). | Lacks 1.2 V operation and IOFF - unsuitable for ultra-low-power or partial power-down designs. | Choose only if TI sourcing preference exists and 1.2 V operation is not required. |
Compared with 74LVCH16245ADGG, the 74LVC16245ADGG,112 trades bus hold for marginally lower static current and identical core functionality; versus SN74LVC16245ADGGR, it offers broader VCC range and certified IOFF protection critical for robust industrial power management.

FAQ
Does 74LVC16245ADGG,112 support 1.2 V operation with full timing guarantees?
Yes. The datasheet specifies guaranteed operation at VCC = 1.2 V across –40 °C to +125 °C, including propagation delay (tpd ≤13.0 ns), enable time (ten ≤15.0 ns), and disable time (tdis ≤11.0 ns), validated per JEDEC JESD8-7A.
Can 74LVC16245ADGG,112 safely interface with 5 V TTL outputs?
Yes. Its inputs tolerate up to 5.5 V regardless of VCC level, and its output HIGH voltage (VOH ≥ VCC – 0.2 V at –24 mA) meets TTL input thresholds when VCC ≥ 2.7 V, enabling direct connection without external level shifters.
What is the purpose of the multiple GND and VCC pins in the TSSOP48 layout?
The eight GND and four VCC pins reduce simultaneous switching noise and ground bounce by distributing return currents and supply paths. This maintains signal integrity for all 32 I/Os during high-frequency bidirectional toggling, as confirmed by Nexperia's low-inductance pin assignment.
How does the IOFF feature behave during power sequencing?
When VCC drops below 0.2 V, the IOFF circuit activates automatically, forcing all outputs into high-impedance and blocking reverse current from live buses into the unpowered IC - verified to limit leakage to ±10 μA at VCC = 0 V and VI/O = 5.5 V.
