Product details
Overview
74LVTN16245BDGG,11 from Nexperia is a 3.3 V, 16-bit non-inverting bus transceiver with dual 3-state outputs, bidirectional data flow controlled by separate direction (nDIR) and output enable (nOE) inputs, ±32 mA/±64 mA drive capability, TTL-compatible I/O, and operation across -40 °C to +85 °C - used in high-speed 3.3 V/5 V mixed-voltage backplane and memory interface buses.
For engineers reviewing the 74LVTN16245BDGG,11 datasheet, 74LVTN16245BDGG,11 pinout, 74LVTN16245BDGG,11 application, or 74LVTN16245BDGG,11 equivalent, key selection criteria include bidirectional 3-state timing margins, 5 V-tolerant inputs/outputs, power-up 3-state behavior, and TSSOP48 thermal and routing constraints for dense PCB layouts.
Technical Context
This BiCMOS transceiver implements two independent 8-bit transceiver blocks (A↔B), each with dedicated nDIR and nOE controls, enabling flexible bus segmentation and cascading without external logic. Its TTL-level input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V) and 5 V-tolerant I/O allow direct interfacing with legacy 5 V systems while operating at 3.3 V supply.
Propagation delays are tightly specified: tPLH/tPHL ≤ 3.3 ns (VCC = 3.0–3.6 V), and enable/disable times (tPZH/tPLZ ≤ 5.1 ns) support >100 MHz bus clocking. The device features live insertion capability, latch-up immunity (>500 mA per JESD78B Class II), and HBM ESD protection exceeding 2000 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 2.7 V to 3.6 V - ensures compatibility with 3.3 V ±10 % rails and avoids overvoltage stress during hot-swap events. |
| IOH / IOL | -32 mA / +64 mA - supports driving heavy capacitive loads (e.g., 50 pF traces) while maintaining VOL ≤ 0.55 V and VOH ≥ 2.0 V at 3.0 V. |
| tPLH / tPHL | 1.0–3.3 ns - enables reliable 100+ MHz data transfer on parallel buses with minimal skew between A/B channels. |
| VIH / VIL | ≥ 2.0 V / ≤ 0.8 V - guarantees clean recognition of 5 V logic HIGH/LOW signals without level shifters. |
| Operating Temp | -40 °C to +85 °C - validated for industrial-grade embedded control and telecom infrastructure environments. |
| ESD Rating | HBM >2000 V, CDM >1000 V - reduces risk of field failure during handling and board assembly. |
| Power-up State | Outputs in 3-state - prevents bus contention during system power sequencing when VCC ramps. |
Pinout & Package
TSSOP48 (SOT362-1) package: 48-pin plastic thin shrink small outline, 6.1 mm body width, 0.5 mm pitch, 1.2 mm max height - optimized for automated placement and thermal dissipation in space-constrained boards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input (active HIGH) | Determines data flow direction per 8-bit bank: HIGH = B→A, LOW = A→B; enables independent bus arbitration. |
| 1OE, 2OE | Output enable input (active LOW) | Asserting LOW enables outputs; HIGH forces high-impedance - essential for bus sharing and hot-plug isolation. |
| 1A0–1A7, 2A0–2A7 | Data I/O port A | First 8-bit bidirectional bus segment; connects to local controller or memory subsystem. |
| 1B0–1B7, 2B0–2B7 | Data I/O port B | Second 8-bit bidirectional bus segment; interfaces to peripheral or expansion bus. |
| VCC (pins 7, 18, 31, 42) | Supply voltage | Four distributed VCC pins reduce IR drop and improve noise immunity across high-speed switching. |
| GND (pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins provide low-inductance return paths critical for signal integrity at >100 MHz edge rates. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V-tolerant I/O | Inputs and outputs withstand up to 7.0 V - eliminates need for external level translators when interfacing with 5 V peripherals. |
| Live insertion/extraction | Validated for hot-swap in backplane systems - prevents damage during board replacement without powering down the chassis. |
| No bus current loading | Outputs draw zero current when tied to 5 V bus in OFF-state - avoids unintended pull-up/pull-down conflicts. |
| Latch-up immunity | JESD78B Class II >500 mA - ensures robustness against transient overvoltage and ground bounce in noisy industrial environments. |
| Power-up 3-state | Outputs remain high-Z until VCC stabilizes - prevents metastability and bus contention during power ramp. |
Applications
| Memory Interface Bus | Backplane Data Link |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16245ADGGR | Lower drive (±24 mA), 1.65–3.6 V VCC range, no 5 V-tolerant inputs - requires external clamping for 5 V I/O. | Suitable only in pure 3.3 V systems; not viable for mixed-voltage backplanes. | Select when cost sensitivity outweighs 5 V interface needs and bus loading is light. |
| 74ALVC16245PW,118 | Same 5 V-tolerant I/O and ±24 mA drive, but slower propagation (≤5.5 ns), higher ICC (0.2 mA typical). | Acceptable for <50 MHz buses where timing margin is relaxed and power budget allows. | Choose if footprint compatibility with TSSOP48 is required but performance headroom is lower. |
Compared with SN74LVC16245ADGGR and 74ALVC16245PW,118, the 74LVTN16245BDGG,11 delivers superior 5 V tolerance, higher sink current, and faster timing - making it the only option among the three qualified for hot-swap-capable, mixed-voltage industrial backplanes.

FAQ
What is the maximum bus capacitance this transceiver can reliably drive?
The 74LVTN16245BDGG,11 is characterized with 50 pF load in dynamic testing (Table 9), and its ±64 mA sink/source capability supports rise/fall times under 3 ns into ≤50 pF. For heavier loads, derate propagation delay and verify VOL/VOH margins per Table 6 at actual VCC and temperature.
Can this device be used with a 2.5 V supply?
No - the recommended VCC range is strictly 2.7 V to 3.6 V (Table 5). At 2.5 V, VOH drops below 2.0 V and VOL exceeds 0.55 V, violating TTL input thresholds and risking logic errors; absolute minimum VCC is 2.7 V per specification.
How does the power-up 3-state behavior work during VCC ramp?
During power-up, outputs remain in high-impedance until VCC reaches ~1.2 V and stabilizes; this is guaranteed by internal circuitry that holds OE logic inactive until supply is valid - preventing bus contention even with asynchronous power sequencing across multiple devices.
Is there any difference between the 74LVTN16245BDGG and 74LVTN16245BDGG,11 suffixes?
Yes - the ,11 suffix denotes tape-and-reel packaging per JEDEC standard (1000 pcs/reel), while the base part number refers to the die and package. Electrical, thermal, and functional specifications are identical; only packaging and reel orientation differ per ordering code SOT362-1 in Table 1.
