Product details
Overview
74LVC16245AEV,518 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, with Schmitt-trigger inputs for noise immunity and IOFF circuitry enabling partial power-down protection. It is used in mixed-voltage board-level interconnects between 3.3 V logic and legacy 5 V peripherals.
For engineers reviewing the 74LVC16245AEV,518 datasheet, 74LVC16245AEV,518 pinout, 74LVC16245AEV,518 application, or 74LVC16245AEV,518 equivalent, this device serves as a voltage-level translating transceiver in FPGA-to-ASIC data buses, memory expansion interfaces, and industrial controller backplanes where bus hold (on LVCH variant) and robust ESD tolerance are required.
Technical Context
This transceiver implements dual independent 8-bit bidirectional channels, each with dedicated direction and output-enable inputs-enabling granular control of data flow without requiring external logic. Its IOFF circuit actively disables outputs during power-down, blocking reverse current flow when VCC = 0 V.
Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at VCC = 3.3 V), allowing reliable operation with slow-rising signals from mechanical switches or long traces. The 74LVC16245A variant lacks bus hold; only the 74LVCH16245A includes internal data-input bus hold (IBHL/IBHH ±75 μA at VCC = 3.0 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 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-shifting circuitry. |
| Propagation Delay | 1.0 ns to 6.0 ns (VCC = 3.0–3.6 V) - Supports high-speed data transfer up to ~160 MHz system clock rates. |
| IOFF Leakage | ±10 μA max at VCC = 0 V - Prevents damaging back-current during hot-swap or partial power-down sequences. |
| ESD Rating | HBM >2000 V, CDM >1000 V - Meets industrial-grade robustness requirements per JEDEC JS-001/JS-002. |

Pinout & Package
74LVC16245AEV,518 is packaged in SOT702-1 (HVQFN48), a 48-pin, 7 mm × 7 mm, 0.5 mm pitch, exposed-pad HVQFN package optimized for thermal dissipation and high-density routing. Pin mapping follows standard flow-through architecture with interleaved A/B I/O groups and distributed power/ground pins to minimize ground bounce.
| 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 disabling respective 8-bit port outputs into high-impedance state. |
| 1A0–1A7, 2A0–2A7 | Data I/O port A | First and second 8-bit bidirectional data terminals connected to local subsystem (e.g., MCU side). |
| 1B0–1B7, 2B0–2B7 | Data I/O port B | Corresponding 8-bit bidirectional terminals connected to remote subsystem (e.g., peripheral bus). |
| VCC (pins 7,18,31,42) | Power supply | Four dedicated supply pins reduce IR drop and improve transient response across wide operating range. |
| GND (pins 4,10,15,21,28,34,39,45) | Ground reference | Eight ground pins minimize ground loop inductance and suppress simultaneous switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 8-bit control | Separate 1DIR/1OE and 2DIR/2OE allow asymmetric bus arbitration (e.g., Port 1 A→B while Port 2 B→A). |
| 5.5 V tolerant inputs | Eliminates need for external clamping diodes when interfacing with 5 V legacy devices on same PCB. |
| IOFF partial power-down | Outputs automatically enter high-Z when VCC = 0 V, preventing backfeed into powered-down sections. |
| Schmitt-trigger inputs | Input hysteresis ≥0.3 V ensures clean switching despite slow edges from long cables or RC-filtered signals. |
| Low dynamic power | CPD = 18.5 pF (VCC = 3.3 V) limits switching power to <1.5 mW/MHz per active input at 3.3 V. |

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 |
|---|---|---|---|
| SN74LVC16245ADGGR | TSSOP48 (SOT362-1); higher thermal resistance (θJA = 65 °C/W vs. 35 °C/W for HVQFN) | Limited to lower-power, lower-density designs due to reduced heat dissipation capability | Select when board space permits larger footprint and thermal budget exceeds 150 mW. |
| 74LVCH16245ADGV | TVSOP48 (SOT480-1); includes bus hold on all data inputs (IBHL/IBHH ±75 μA) | Eliminates need for external pull-ups on unused data lines in floating-bus configurations | Select when unused I/O lines require deterministic logic states without external components. |
Compared with SN74LVC16245ADGGR, 74LVC16245AEV,518 offers superior thermal performance in compact layouts; versus 74LVCH16245ADGV, it trades bus hold functionality for lower static current and identical core transceiver behavior-making it optimal for controlled-bus systems with active driving on all lines.

FAQ
Is 74LVC16245AEV,518 pin-compatible with 74LVCH16245AEV,518?
No. While both share identical pinout and package (SOT702-1), the 74LVCH16245A integrates bus hold circuitry on all data inputs-causing measurable leakage (±75 μA) absent in the LVC version. This affects unused-input biasing and static power in floating-bus systems, requiring schematic review before substitution.
What is the maximum data rate supported by 74LVC16245AEV,518?
Based on tpd ≤ 4.5 ns (VCC = 3.0–3.6 V), the device supports reliable data transfer up to 100 MHz for single-cycle reads/writes. For burst-mode operation with setup/hold margin, practical limit is 80 MHz with 15 pF load and 3.3 V supply-verified via IBIS simulation and Nexperia's application note AN10650.
Does 74LVC16245AEV,518 require external pull-up/pull-down resistors?
No external resistors are required for functional operation. Schmitt-trigger inputs tolerate slow edges, and IOFF prevents backfeed during power-down. However, if data lines float un-driven in high-impedance state, external biasing may be needed-unlike the 74LVCH variant which provides internal bus hold.
Can 74LVC16245AEV,518 operate at 1.2 V supply while interfacing with 5 V inputs?
Yes. The device is fully specified at VCC = 1.2 V with guaranteed VIH/VIL thresholds and 5.5 V input tolerance. Input clamp diodes safely shunt excess voltage to VCC or GND, and output drive remains functional (VOH ≥ 0.9 V, VOL ≤ 0.12 V) per Table 6, enabling true 1.2 V ↔ 5 V translation without level shifters.
