Product details
Overview
74LVC16245AEV/G,55 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 5.5 V inputs, and features IOFF partial power-down protection. Used in mixed-voltage board-level interconnects between 3.3 V logic and legacy 5 V peripherals.
For engineers reviewing the 74LVC16245AEV/G,55 datasheet, 74LVC16245AEV/G,55 pinout, 74LVC16245AEV/G,55 application, or 74LVC16245AEV/G,55 equivalent, this device serves as a voltage-tolerant, low-noise bidirectional interface for FPGA-to-ASIC communication, memory expansion buses, and industrial controller backplanes requiring robust 3-state control and bus hold functionality.
Technical Context
This transceiver implements dual independent 8-bit flow-through architecture with Schmitt-trigger inputs for noise immunity and defined hysteresis. Each port pair (A/B) is controlled by dedicated DIR and OE signals, enabling asymmetric enable timing and independent direction switching per byte lane.
The IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V, while bus hold (on 74LVCH variant) maintains valid logic states on unused data inputs without external pull-ups - critical for hot-swap and partial-power systems.
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 families. |
| Input Voltage Tolerance | Up to 5.5 V - Allows safe connection to 5 V signal sources without level shifters. |
| Propagation Delay (tpd) | 1.0 ns (min) to 6.0 ns (max) at VCC = 3.0–3.6 V - Supports high-speed parallel bus operation up to ~100 MHz effective throughput. |
| IOFF Leakage Current | ±10 μA max at VCC = 0 V - Ensures <100 μW standby power and prevents backfeeding in powered-down subsystems. |
| Bus Hold Current (74LVCH) | ±60 μA to ±75 μA - Maintains stable logic state on floating A/B data pins without external resistors. |
| ESD Rating (HBM) | >2000 V - Meets JEDEC JS-001 Class 2 for robust handling in manufacturing and field environments. |
| Operating Temperature | -40 °C to +125 °C - Qualified for extended industrial and automotive under-hood applications. |
Pinout & Package
74LVC16245AEV/G,55 is packaged in SOT702-1 (HVQFN48), a 48-pin plastic HVQFN with 0.4 mm pitch, 7.0 mm × 7.0 mm body, and exposed thermal pad. This package provides low-inductance power/ground paths and superior thermal performance vs. TSSOP/TVSOP alternatives.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Active-HIGH logic selects data flow direction per 8-bit port: HIGH = A→B, LOW = B→A. |
| 1OE, 2OE | Output enable input | Active-LOW control enables/disables 3-state outputs for each port independently. |
| 1A0–1A7, 2A0–2A7 | Data I/O port A | First and second 8-bit bidirectional data terminals connected to local bus side. |
| 1B0–1B7, 2B0–2B7 | Data I/O port B | First and second 8-bit bidirectional data terminals connected to remote bus side. |
| VCC (Pins 7, 18, 31, 42) | Power supply | Four distributed VCC pins minimize IR drop and supply noise across wide bus. |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins ensure low-impedance return path and reduce ground bounce in high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 8-bit control | Separate DIR/OE per byte lane enables asymmetric timing and selective port isolation in multi-master systems. |
| IOFF partial power-down | Outputs disable automatically when VCC = 0 V, preventing damaging back-current during hot-plug or sleep-mode transitions. |
| Schmitt-trigger inputs | Hysteresis >0.3 V at VCC = 3.3 V rejects slow-rising/falling noise on long traces or unterminated lines. |
| 5.5 V tolerant inputs | Accepts TTL/5 V CMOS logic levels directly - eliminates need for discrete level translators in mixed-voltage designs. |
| Low dynamic power dissipation | CPD = 18.5 pF at VCC = 3.3 V - reduces switching power to <1 mW per active transition at 10 MHz. |
Applications
| Industrial PLC Backplane Interface | FPGA-to-ASIC Data Bridge |

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 | TVSOP48 package (SOT480-1); includes bus hold on all data inputs; identical electrical specs. | Surface-mount footprint differs; bus hold eliminates need for external pull-ups on unused pins. | Select when board layout requires smaller body width (4.4 mm) and bus hold is required for floating-input reliability. |
| SN74LVC16245ADGGR | TSSOP48 package (TI); no bus hold; IOFF and 5.5 V tolerance confirmed; propagation delay slightly higher (max 7.5 ns). | Lacks bus hold; requires external termination for unused inputs; same temperature range (-40 °C to +125 °C). | Select when sourcing from TI distribution channels or when bus hold is not needed and cost is prioritized over pin-compatible replacement. |

FAQ
What is the function of the IOFF circuit in 74LVC16245AEV/G,55?
The IOFF circuit disables all outputs when VCC = 0 V, preventing backflow current from live bus lines into the unpowered IC. This protects downstream circuitry during partial power-down, hot-swap events, or system reset sequences - verified per JEDEC JESD78 with leakage ≤±10 μA at VCC = 0 V and VI/O = 5.5 V.
Does 74LVC16245AEV/G,55 include bus hold functionality?
No - bus hold is exclusive to the 74LVCH16245A variant. The 74LVC16245AEV/G,55 lacks internal bus hold circuitry on data inputs. Unused A/B pins must be externally terminated with pull-up or pull-down resistors to prevent floating states and potential shoot-through current.
Can 74LVC16245AEV/G,55 operate with a 1.2 V supply and interface to 5 V inputs simultaneously?
Yes - it is fully specified from 1.2 V to 3.6 V VCC and accepts input voltages up to 5.5 V regardless of supply level. Input clamping diodes and oxide-thickness design ensure safe 5 V signal injection at 1.2 V operation, validated per JESD8-7A and absolute maximum ratings.
What is the thermal pad connection requirement for SOT702-1 (HVQFN48) package?
The exposed thermal pad (Pin 49) must be soldered to a solid copper thermal land on the PCB, connected to GND for optimal heat dissipation and EMI suppression. Thermal resistance θJA drops from 42 °C/W (no pad) to 28 °C/W (with 200 mm² 2-layer GND pour), critical for sustained 24 mA per output operation at +125 °C ambient.
