Product details
Overview
74ALVC16245DL,118 from Nexperia is a 16-bit dual-directional bus transceiver with 3-state outputs, two independent direction controls (1DIR, 2DIR), and two output enables (1OE, 2OE). It operates across 1.2 V to 3.6 V supply, delivers ±24 mA drive at 3.0 V, and features Schmitt-trigger inputs for noise immunity. Used in high-density PCB interconnects between microcontrollers and peripheral buses.
For engineers reviewing the 74ALVC16245DL,118 datasheet, 74ALVC16245DL,118 pinout, 74ALVC16245DL,118 application, or 74ALVC16245DL,118 equivalent, key selection criteria include bidirectional flow-through pinout, IOFF partial power-down support, overvoltage-tolerant inputs up to 5.5 V, and TSSOP48 package compatibility with high-pin-count logic routing.
Technical Context
This device implements two independent 8-bit transceiver sections sharing no internal coupling-each with dedicated DIR and OE control. Direction logic determines data flow per section: LOW on nDIR enables A→B transfer; HIGH enables B→A transfer. Output enable is active-LOW, placing outputs in high-impedance state when asserted.
The 74ALVC16245 variant includes overvoltage-tolerant inputs (up to 5.5 V) while maintaining 3.6 V VCC max, enabling safe interfacing with legacy 5 V logic without level shifters. IOFF circuitry disables outputs during partial power-down, preventing backflow current when VCC = 0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.2 V to 3.6 V - supports mixed-voltage system integration including 1.8 V, 2.5 V, and 3.3 V domains |
| Output Drive | ±24 mA at 3.0 V - drives 50 Ω transmission lines directly at 85 °C without external buffers |
| Propagation Delay | 1.0–3.0 ns (VCC = 3.0–3.6 V) - enables sub-300 MHz bus operation with tight timing margins |
| IOFF Support | Yes - prevents damaging back-current during hot-insertion or partial power-down sequences |
| Input Tolerance | Up to 5.5 V - allows direct connection to 5 V TTL outputs without clamping diodes or resistors |
| Operating Temp | −40 °C to +85 °C - qualified for industrial-grade embedded and communications equipment |
| ESD Rating | HBM >2000 V, CDM >1000 V - robust handling in automated assembly and field service environments |
Pinout & Package
TSSOP48 (SOT362-1) package: plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm lead pitch, designed for fine-pitch PCB routing and thermal performance in dense logic arrays.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Active-HIGH selects B→A data flow; LOW selects A→B - enables independent bidirectional control per 8-bit bank |
| 1OE, 2OE | Output enable input | Active-LOW disables corresponding 8-bit output bank - supports selective bus isolation without affecting other sections |
| 1A0–1A7, 2A0–2A7 | Data port A terminals | Primary I/O interface for first/second 8-bit bus segment - flow-through layout minimizes trace crossovers |
| 1B0–1B7, 2B0–2B7 | Data port B terminals | Secondary I/O interface - paired with A ports to form full 16-bit bidirectional channel or dual 8-bit channels |
| VCC (pins 7, 18, 31, 42) | Power supply | Multiple distributed VCC pins reduce simultaneous switching noise and improve PDN stability |
| GND (pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins minimize ground bounce and ensure signal integrity across all 16 data paths |
Key Features
| Feature | Design Value |
|---|---|
| MULTIBYTE™ flow-through pinout | Linear A/B port arrangement simplifies PCB layout and reduces layer count in high-speed bus routing |
| Schmitt-trigger inputs | Slow-edge tolerance eliminates need for external RC filtering on noisy or long-trace control signals |
| IOFF partial power-down | Outputs automatically disable when VCC = 0 V - essential for hot-swap and power-gated subsystems |
| Overvoltage-tolerant inputs | 5.5 V max input voltage with 3.6 V VCC - enables interoperability with legacy 5 V logic without level translators |
| Low-noise power distribution | Four VCC and eight GND pins suppress simultaneous switching output (SSO) noise in multi-bit applications |

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 |
|---|---|---|---|
| SN74ALVCH16245DGGR | Includes bus-hold circuitry on all data inputs; lacks 5.5 V input tolerance | Eliminates need for external pull-ups on unused inputs; requires strict 3.6 V max VCC | Select when floating input management is critical and system uses only 3.3 V logic |
| 74LVC16245APAG | Same pinout but rated only to 3.3 V VCC; no overvoltage tolerance; lower drive (±24 mA at 3.3 V only) | Not suitable for 5 V-tolerant interfaces; limited to single-supply 3.3 V systems | Select for cost-sensitive 3.3 V-only designs where 5 V compatibility is unnecessary |
Compared with SN74ALVCH16245DGGR and 74LVC16245APAG, the 74ALVC16245DL,118 uniquely combines 5.5 V input tolerance with full 1.2–3.6 V operation and IOFF, making it optimal for mixed-voltage industrial backplanes requiring hot-swap resilience and legacy interface support.

The 74ALVC16245DL,118 supports input voltages up to 5.5 V on all data and control pins, regardless of VCC level (1.2 V to 3.6 V). This overvoltage tolerance enables direct interfacing with 5 V TTL outputs without external level-shifting components, verified per datasheet Table 4 limiting values and Section 2 features.
Does 74ALVC16245DL,118 support partial power-down operation?
Yes - the device integrates IOFF circuitry that automatically disables outputs and blocks backflow current when VCC is at 0 V.
