Product details
Overview
74LVC16245AEV,118 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 interface in mixed-voltage systems (e.g., 3.3 V logic interfacing to 5 V peripherals). Its IOFF circuitry prevents backflow current during partial power-down, and Schmitt-trigger inputs tolerate slow signal edges.
For engineers reviewing the 74LVC16245AEV,118 datasheet, 74LVC16245AEV,118 pinout, 74LVC16245AEV,118 application, or 74LVC16245AEV,118 equivalent, this device is selected for voltage-level translation, high-noise industrial bus isolation, and hot-swap-capable memory/data bus expansion where low static power, rail-to-rail input tolerance, and guaranteed 3-state timing are critical.
Technical Context
This transceiver implements dual independent 8-bit bidirectional channels, each with dedicated DIR and OE controls-enabling asymmetric enablement and direction assignment per byte lane. The IOFF feature actively disables outputs when VCC = 0 V, blocking destructive current paths in powered-down subsystems.
All inputs include Schmitt-trigger action for noise immunity on slow-rising signals, and the 74LVC variant (vs. LVCH) omits bus-hold circuitry on data pins-requiring external termination for unused I/Os. The device complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36 across its full 1.2 V–3.6 V VCC range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.2 V to 3.6 V - Enables operation in ultra-low-power IoT nodes and standard 3.3 V systems without level shifters. |
| Input Voltage Tolerance | −0.5 V to +5.5 V - Allows direct connection to 5 V TTL or CMOS sources without external clamping diodes. |
| tpd (Propagation Delay) | 1.0 ns to 6.0 ns (VCC = 3.0–3.6 V) - Ensures sub-6 ns latency for high-speed address/data bus handshaking. |
| IOFF Leakage | ±10 μA max at VCC = 0 V - Guarantees safe isolation during system sleep or hot-plug events. |
| Operating Temperature | −40 °C to +125 °C - Qualified for under-hood automotive modules and industrial motor drives. |
| ESD Rating (HBM) | >2000 V - Meets IEC 61000-4-2 Level 2 for robustness in assembly and field environments. |
| Output Drive | ±24 mA (VCC = 3.0 V) - Sufficient to drive 15 pF loads across 10 cm PCB traces at 100 MHz. |
Pinout & Package
74LVC16245AEV,118 is packaged in SOT702-1 (HVQFN48), a 48-pin, 7 mm × 7 mm, 0.5 mm pitch quad flat no-lead package with exposed thermal pad. This package provides low-inductance grounding and enhanced thermal dissipation for sustained 16-bit bus switching.
| 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 (Z) mode. |
| 1A0–1A7, 2A0–2A7 | Port A data I/O (side A) | First and second 8-bit bidirectional data lanes connected to local controller or processor bus. |
| 1B0–1B7, 2B0–2B7 | Port B data I/O (side B) | Corresponding 8-bit bidirectional lanes connected to peripheral bus, memory, or external interface. |
| VCC | Supply voltage (1.2–3.6 V) | Four dedicated VCC pins (pins 7, 18, 31, 42) minimize IR drop and supply noise across wide bus. |
| GND | Ground reference | Eight GND pins (pins 4, 10, 15, 21, 28, 34, 39, 45) reduce ground bounce and improve signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 8-bit control | Separate 1DIR/1OE and 2DIR/2OE allow asymmetric configuration-e.g., Port 1 A→B while Port 2 B→A simultaneously. |
| 5.5 V tolerant inputs | Eliminates need for external level translators when interfacing legacy 5 V peripherals to modern 3.3 V SoCs. |
| IOFF partial power-down | Prevents damaging back-current from live buses into unpowered logic sections-critical for modular hot-swap systems. |
| Schmitt-trigger inputs | Provides >0.5 V hysteresis, enabling reliable operation with slow-edge clocks or noisy industrial sensor signals. |
| Low dynamic power | CPD = 18.5 pF (VCC = 3.3 V) limits switching power to <1.5 mW/MHz per port-ideal for battery-powered gateways. |
Applications
| Industrial PLC Backplane Interface | Automotive ADAS Sensor Hub |

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; identical pinout and electrical specs otherwise. | Eliminates need for external pull-ups on floating data lines-reduces BOM count in low-pin-count designs. | Select when unused I/Os must retain last valid state without external components. |
| SN74LVC16245ADGGR | Texas Instruments variant; same VCC range and 5.5 V tolerance, but higher ICC (max 80 μA vs. 20 μA). | Higher static current may impact battery life in always-on monitoring nodes. | Select only if TI supply chain preference or existing design reuse outweighs 4× higher quiescent power. |
Compared with 74LVCH16245ADGV, the 74LVC16245AEV,118 trades bus-hold functionality for lower leakage and reduced silicon area-making it preferable in cost-sensitive, externally terminated systems. Against SN74LVC16245ADGGR, it delivers superior static power efficiency critical for energy-constrained edge devices.

FAQ
Is 74LVC16245AEV,118 pin-compatible with 74LVC16245ADGG?
Yes-both use the same functional pin mapping and 48-pin layout. However, 74LVC16245AEV,118 is in SOT702-1 (HVQFN48), while 74LVC16245ADGG uses SOT362-1 (TSSOP48). Physical mounting differs: HVQFN requires reflow profile optimization and solder paste stencil adjustment due to its bottom thermal pad and fine pitch.
Does 74LVC16245AEV,118 support hot insertion?
Yes-its IOFF circuitry actively disables outputs when VCC = 0 V, preventing back-current from live backplane traces into unpowered circuitry. This meets IEC 61000-4-2 Level 2 ESD robustness and allows safe insertion into powered systems, provided VCC ramp rates comply with datasheet recommendations (≤1 V/ms).
What is the maximum capacitive load this transceiver can drive reliably?
At VCC = 3.3 V and Tamb = 25 °C, the device maintains specified tpd and VOH/VOL with up to 50 pF total load capacitance (including PCB trace, probe, and destination input). Driving >50 pF increases propagation delay nonlinearly and may violate setup/hold timing in synchronous interfaces.
Can unused data pins be left floating?
No-74LVC16245AEV,118 lacks bus-hold circuitry. Floating inputs risk metastability, increased ICC, and EMI susceptibility. Unused data pins (1A0–1A7, 1B0–1B7, etc.) must be tied HIGH or LOW via ≤10 kΩ resistors to VCC or GND per JEDEC JESD78 guidelines.
