Product details
Overview
74LVC16245AEV,151 from Nexperia is a 16-bit 3-state bus transceiver with dual direction control (1DIR/2DIR) and dual output enable (1OE/2OE), operating from 1.2 V to 3.6 V supply while tolerating 5.5 V 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, FPGA I/O buffering, and industrial backplane interfaces.
For engineers reviewing the 74LVC16245AEV,151 datasheet, 74LVC16245AEV,151 pinout, 74LVC16245AEV,151 application, or 74LVC16245AEV,151 equivalent, this device delivers verified 5.5 V-tolerant inputs, IOFF partial power-down protection, Schmitt-trigger input noise immunity, and bus-hold functionality (on LVCH variant), making it critical for mixed-voltage system interconnects requiring deterministic high-impedance state control and robust static/dynamic timing.
Technical Context
This transceiver implements dual independent 8-bit bidirectional channels, each with dedicated DIR and OE pins-enabling granular control of data flow direction and output state per port. Its CMOS architecture supports rail-to-rail input thresholds defined by VCC-dependent VIH/VIL levels, and features IOFF circuitry that actively disables outputs during power-down to prevent backflow current.
Schmitt-trigger inputs provide hysteresis (≥0.3 V typical) for reliable operation with slow-rising signals, while the bus-hold function on data inputs (74LVCH16245A variant) maintains last-valid logic state without external pull-ups. Propagation delay is specified down to 1.0 ns at VCC = 3.0–3.6 V, with enable/disable times under 7.0 ns across full temperature range (−40 °C to +125 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.2 V to 3.6 V - Enables direct interface with low-voltage logic (1.2 V ASICs, 1.8 V FPGAs) while maintaining compatibility with 3.3 V systems. |
| Input Voltage Tolerance | Up to 5.5 V - Allows safe connection to 5 V legacy buses without level-shifting components, critical for mixed-voltage board design. |
| Propagation Delay (tpd) | 1.0 ns (min) to 4.5 ns (max) at VCC = 3.0–3.6 V - Ensures sub-5 ns timing margin for high-speed parallel bus applications up to ~200 MHz effective throughput. |
| IOFF Leakage Current | ±10 μA max at VCC = 0 V - Guarantees <10 μA backflow during partial power-down, protecting powered subsystems from unintended current paths. |
| Operating Temperature | −40 °C to +125 °C - Qualified for extended industrial and automotive under-hood environments where thermal stability is mandatory. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Meets JEDEC JS-001/JS-002 Class 2/C3 requirements, reducing susceptibility to handling damage in manufacturing. |
| Bus Hold Current | ±75 μA at VCC = 3.0 V - Maintains stable logic state on floating data inputs without external resistors, simplifying PCB layout and BOM. |
Pinout & Package
74LVC16245AEV,151 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 power/ground connections and superior thermal performance over TSSOP/TVSOP variants.
| 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; enables independent bidirectional control of two data lanes. |
| 1OE, 2OE | Output enable input (active LOW) | Asserting LOW enables corresponding 8-bit port outputs; HIGH forces high-impedance state-essential for bus arbitration and multi-drop sharing. |
| 1A0–1A7, 2A0–2A7 | Data I/O port A (side A) | First and second 8-bit data terminals connected to one system domain (e.g., microcontroller side); electrically identical to B-side but isolated by DIR/OE logic. |
| 1B0–1B7, 2B0–2B7 | Data I/O port B (side B) | Second 8-bit data terminals connected to peripheral/memory side; bidirectional path controlled independently per port via DIR/OE pairing. |
| VCC | Power supply | Single 1.2–3.6 V supply powers entire device; multiple VCC pins (pins 7, 18, 31, 42 in TSSOP) reduce IR drop and switching noise. |
| GND | Ground reference | Eight dedicated GND pins (pins 4, 10, 15, 21, 28, 34, 39, 45 in TSSOP) 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 pins allow concurrent yet distinct direction and enable states for two data groups-critical for asymmetric bus architectures. |
| 5.5 V tolerant inputs | Inputs accept up to 5.5 V regardless of VCC (1.2–3.6 V), eliminating need for external voltage translators when interfacing with 5 V peripherals or legacy controllers. |
| IOFF partial power-down | Outputs automatically enter high-Z when VCC = 0 V, preventing damaging back-current into powered downstream circuits during hot-swap or power sequencing events. |
| Schmitt-trigger inputs | Input hysteresis ≥0.3 V suppresses noise-induced glitches on slow-rising/falling signals (e.g., mechanical switches, long traces), improving system reliability. |
| Bus-hold on data inputs | Internal weak keepers (±75 μA at 3.0 V) retain last logic state on unused or floating data lines-reducing component count and routing complexity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVCH16245ADGV | Identical logic and pinout, but in TVSOP48 (SOT480-1) package with 0.4 mm pitch and 4.4 mm body width-smaller footprint than SOT702-1. | Preferred for space-constrained PCBs where QFN thermal pad assembly is not feasible; lacks exposed pad for enhanced thermal dissipation. | Select when board real estate is critical and thermal load is moderate (<100 mW); verify reflow profile compatibility with fine-pitch TVSOP. |
| SN74LVC16245ADGGR | Texas Instruments variant in TSSOP48 (same SOT362-1 footprint), with identical electrical specs but different IOFF leakage (±20 μA vs. ±10 μA) and slightly higher tpd (max 5.5 ns). | Valid for drop-in replacement in existing TI-design boards; requires validation of IOFF behavior in partial-power-down sequences. | Choose only if TI supply chain alignment or legacy design continuity is required; confirm thermal derating matches Nexperia's 12.2 mW/K above 109 °C. |
Compared with 74LVCH16245ADGV, the 74LVC16245AEV,151 offers superior thermal performance via its HVQFN thermal pad but requires more complex assembly; versus SN74LVC16245ADGGR, it delivers tighter IOFF leakage and faster timing, making it preferable for safety-critical or high-reliability industrial deployments.

FAQ
Is 74LVC16245AEV,151 pin-compatible with standard 74LVC16245A packages like TSSOP48?
No-74LVC16245AEV,151 uses SOT702-1 (HVQFN48), which has a different pin map and land pattern than TSSOP48 (SOT362-1) or TVSOP48 (SOT480-1). Pin functions match, but physical layout, thermal pad presence, and soldering requirements differ significantly. Mechanical redesign and requalification are required for substitution.
Does 74LVC16245AEV,151 include bus-hold functionality?
No-bus-hold is exclusive to the 74LVCH16245A variant. The 74LVC16245AEV,151 lacks internal bus-hold circuitry on data inputs. External pull-up/pull-down resistors must be used on unused inputs to prevent floating states, unlike the LVCH version which retains last logic value autonomously.
What is the maximum data rate supported by 74LVC16245AEV,151 in a 16-bit parallel bus?
Based on worst-case propagation delay of 4.5 ns (VCC = 3.0–3.6 V) and disable time of 7.0 ns, the device supports reliable operation up to approximately 85 MHz clock frequency (11.8 ns minimum cycle time), assuming clean signal integrity, matched trace lengths, and ≤30 pF load capacitance per line.
Can 74LVC16245AEV,151 be used in automotive applications?
While qualified for −40 °C to +125 °C operation, 74LVC16245AEV,151 is not AEC-Q100 qualified and is explicitly designated as non-automotive by Nexperia. It may be used in non-safety-critical infotainment or telematics subsystems only after full customer validation-including PPAP, stress testing, and failure mode analysis-but carries no automotive warranty or liability coverage.
