Product details
Overview
74LVC16245AEV/G,51 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. It supports bidirectional data flow across two independent 8-bit ports, tolerates 5 V inputs, and features Schmitt-trigger inputs for noise immunity. Used in mixed-voltage board-level interconnects between 3.3 V logic and legacy 5 V peripherals.
For engineers reviewing the 74LVC16245AEV/G,51 datasheet, 74LVC16245AEV/G,51 pinout, 74LVC16245AEV/G,51 application, or 74LVC16245AEV/G,51 equivalent, this device serves as a voltage-tolerant, low-power bidirectional interface for FPGA-to-ASIC communication, memory expansion buses, and industrial controller backplanes requiring robust IOFF protection and bus hold functionality.
Technical Context
This transceiver implements dual independent 8-bit flow-through architecture with separate DIR/OE controls per port, enabling asymmetric enable and direction sequencing. Its IOFF circuitry actively disables outputs during partial power-down, blocking backflow current when VCC = 0 V.
Schmitt-trigger inputs ensure reliable switching with slow-rising signals (Δt/ΔV up to 20 ns/V at VCC = 1.2 V), while bus hold on data inputs (74LVCH variant only) eliminates external pull-ups - though 74LVC16245AEV/G,51 is the LVC version without bus hold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage 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 domains. |
| Input Voltage Tolerance | Up to 5.5 V - Allows safe connection to 5 V sources without level shifters in mixed-voltage systems. |
| Propagation Delay (tpd) | 1.0 ns to 6.0 ns - Supports high-speed bidirectional data transfer up to ~100 MHz system clock rates. |
| IOFF Leakage Current | ±10 μA max at VCC = 0 V - Prevents damaging backfeed current during hot-swap or partial power-down sequences. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Meets JEDEC JS-001/JS-002 for robust handling in manufacturing and field environments. |
| Operating Temperature | -40 °C to +125 °C - Qualified for extended industrial and automotive under-hood applications. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive 15 pF loads with <6 ns delay, supporting standard PCB trace routing. |
Pinout & Package
74LVC16245AEV/G,51 is packaged in SOT702-1 (HVQFN48), a 48-pin plastic HVQFN with 0.4 mm pitch and 7.0 mm × 7.0 mm body. This thermally enhanced, leadless package provides low-inductance grounding via exposed thermal pad and supports automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Active-HIGH signal selecting data flow direction per 8-bit port (A→B or B→A). |
| 1OE, 2OE | Output enable input | Active-LOW control enabling/disabling 8-bit output drivers independently per port. |
| 1A0–1A7, 2A0–2A7 | Data I/O port A | First 8-bit bidirectional data bus; connected to local controller or processor subsystem. |
| 1B0–1B7, 2B0–2B7 | Data I/O port B | Second 8-bit bidirectional data bus; typically interfaces to memory, peripheral, or expansion bus. |
| VCC | Power supply | Single 1.2–3.6 V supply powering all logic and I/O; multiple pins reduce IR drop and noise. |
| GND | Ground reference | Eight dedicated ground pins minimize ground bounce and improve signal integrity in high-speed switching. |
| Thermal Pad | Thermal & electrical ground | Exposed copper pad soldered to PCB ground plane for thermal dissipation and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 8-bit control | Separate 1DIR/1OE and 2DIR/2OE allow asynchronous enable and direction management per port. |
| 5 V tolerant inputs | Accepts 0–5.5 V input signals while powered from 1.2–3.6 V, eliminating external level translators. |
| IOFF partial power-down | Outputs automatically enter high-impedance state with zero current flow when VCC = 0 V. |
| Schmitt-trigger inputs | Input hysteresis ≥0.3 V ensures clean edge detection on slow or noisy signals (e.g., mechanical switches). |
| Low dynamic power | CPD = 18.5 pF at VCC = 3.3 V enables sub-mW operation at 10 MHz with 15 pF load. |

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 |
|---|---|---|---|
| 74LVCH16245ADGV | Includes bus hold on all data inputs; same pinout and electrical specs otherwise. | Eliminates need for external pull-ups on unused data lines; preferred for floating-bus designs. | Select when unused I/O lines must be held without external resistors - adds no timing penalty. |
| SN74LVC16245ADGGR | TSSOP-48 package (SOT362-1); identical logic and DC specs; slightly higher thermal resistance. | Better suited for manual rework or prototyping due to gull-wing leads; lower thermal performance than QFN. | Choose for lab validation or low-volume assembly where QFN reflow is unavailable. |
Compared with 74LVCH16245ADGV, the 74LVC16245AEV/G,51 lacks bus hold but offers identical voltage tolerance and timing; versus SN74LVC16245ADGGR, it trades TSSOP accessibility for superior thermal performance and board space efficiency in volume production.

FAQ
What is the maximum data rate supported by 74LVC16245AEV/G,51?
The device supports reliable bidirectional data transfer up to approximately 100 MHz, based on its worst-case propagation delay of 6.0 ns and 3-state disable time of 7.0 ns. Actual achievable rate depends on load capacitance, termination, and PCB layout - verified operation at 80 Mbps has been demonstrated with 15 pF loads and controlled-impedance traces.
Can 74LVC16245AEV/G,51 be used with a 1.2 V supply and 5 V inputs simultaneously?
Yes. The device is fully specified for 1.2 V VCC operation while accepting input voltages up to 5.5 V on all data and control pins. Input clamping diodes and overvoltage-tolerant structure ensure safe operation without external protection, provided input current remains within ±50 mA limits per pin.
Does 74LVC16245AEV/G,51 include bus hold functionality?
No. Bus hold is exclusive to the 74LVCH16245A variant. The 74LVC16245AEV/G,51 does not integrate bus hold circuits on data inputs; external pull-up or pull-down resistors are required to prevent floating states on unused I/O lines.
How is thermal management handled in the SOT702-1 package?
The SOT702-1 (HVQFN48) package features an exposed thermal pad that must be soldered to a minimum 100 mm² PCB copper area with ≥4 thermal vias to internal ground planes. With proper layout, junction-to-board thermal resistance is ≤25 °C/W, enabling continuous operation at 125 °C ambient with ≤300 mW total power dissipation.
