Product details
Overview
74LVCH16245ADL,118 from Nexperia is a 16-bit non-inverting bus transceiver with dual 8-bit direction control (1DIR/2DIR), dual 3-state output enables (1OE/2OE), and bus-hold inputs. It operates from 1.2 V to 3.6 V, tolerates 5.5 V inputs, and supports mixed-voltage translation between 3.3 V and 5 V systems. Used in high-density PCBs for bidirectional data routing in industrial controllers and memory expansion interfaces.
For engineers reviewing the 74LVCH16245ADL,118 datasheet, 74LVCH16245ADL pinout, 74LVCH16245ADL application, or 74LVCH16245ADL equivalent, this device delivers verified 5.5 V-tolerant I/O, IOFF partial power-down protection, Schmitt-trigger noise immunity, and bus-hold functionality eliminating external pull-ups - critical for robust signal integrity in multi-rail embedded systems.
Technical Context
This transceiver implements two independent 8-bit bidirectional data paths, each with dedicated direction (DIR) and output enable (OE) controls. Its IOFF circuit actively disables outputs during power-down to prevent backflow current, satisfying JEDEC JESD78 requirements for partial power-down operation.
All 32 data I/O pins (1A0–1A7, 1B0–1B7, 2A0–2A7, 2B0–2B7) feature integrated bus-hold circuits (74LVCH variant only), sustaining logic states without external resistors. Inputs include Schmitt-trigger action for reliable operation with slow-rising signals, and absolute maximum ratings support 5.5 V input overvoltage tolerance regardless of VCC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 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 | −0.5 V to +5.5 V - Allows safe connection to 5 V sources without level shifters in mixed-voltage systems. |
| Propagation Delay (VCC = 3.3 V) | 1.0 ns to 4.5 ns - Supports high-speed data transfer up to ~220 MHz system clock edge rates. |
| IOFF Leakage Current (VCC = 0 V) | ±10 μA max - Ensures <100 nW standby power and prevents damaging back-current during hot-swap or partial power-down. |
| Bus-Hold Sustaining Current | ±10 μA to ±75 μA - Maintains valid logic state at data inputs without external biasing components. |
| Operating Temperature Range | −40 °C to +125 °C - Qualified for extended industrial and under-hood automotive-adjacent applications. |
| ESD Protection (HBM) | ≥2000 V - Meets ANSI/ESDA/JEDEC JS-001 Class 2, reducing board-level ESD mitigation overhead. |
Pinout & Package
TSSOP48 (SOT362-1) package: plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm lead pitch. Pin 1 index marked; lead finish: matte tin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Active HIGH selects A→B data flow; LOW selects B→A - enables independent bidirectional control per 8-bit port. |
| 1OE, 2OE | Output enable input (active LOW) | Drives corresponding 8-bit output group into high-impedance state when HIGH - supports dynamic bus arbitration. |
| 1A0–1A7, 2A0–2A7 | Data I/O port A | Primary bidirectional data terminals for first and second 8-bit channels - internally connected to bus-hold circuitry. |
| 1B0–1B7, 2B0–2B7 | Data I/O port B | Secondary bidirectional data terminals - electrically isolated per channel; identical voltage tolerance and timing behavior as port A. |
| VCC (pins 7, 18, 31, 42) | Power supply | Four distributed VCC pins minimize IR drop and improve PSRR across high-speed switching events. |
| GND (pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins reduce ground bounce and provide low-inductance return paths for all I/O groups. |
Key Features
| Feature | Design Value |
|---|---|
| 5.5 V tolerant inputs | Enables direct interfacing with legacy 5 V peripherals without external level translators or voltage dividers. |
| IOFF partial power-down | Automatically disables outputs and limits leakage to ±10 μA when VCC = 0 V - essential for hot-plug and power-gating designs. |
| Integrated bus-hold on all data inputs | Eliminates need for 10 kΩ external pull-up/down resistors on unused or floating data lines - reduces BOM count and layout area. |
| Schmitt-trigger inputs | Provides >0.3 V hysteresis - rejects noise on slow-rising/falling signals from mechanical switches, long traces, or unterminated buses. |
| JEDEC-compliant voltage ranges | Fully supports JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V) - ensures interoperability across standard logic families. |

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 |
|---|---|---|---|
| 74LVC16245ADGG | Lacks bus-hold circuitry; otherwise identical pinout, timing, and voltage specs. | Requires external pull-up/pull-down resistors on unused data lines - increases component count and board area. | Select when bus-hold is unnecessary and cost minimization is prioritized over design simplicity. |
| SN74LVC16245ADGGR | TI part; same 48-pin TSSOP package but different thermal pad layout and slightly higher ICC (max 80 μA vs 20 μA). | Compatible in signal routing but requires verification of thermal performance under continuous 16-bit switching at +125 °C. | Choose only if TI's supply chain assurance or existing qualification documentation is required for OEM compliance. |
Compared with 74LVC16245ADGG, the 74LVCH16245ADL,118 adds bus-hold to reduce external components, while versus SN74LVC16245ADGGR it offers lower static current and guaranteed Nexperia industrial temperature qualification - making it optimal for compact, thermally constrained, or high-reliability embedded designs.

FAQ
Does 74LVCH16245ADL,118 support true 5 V operation?
No - its VCC must remain within 1.2 V to 3.6 V. However, all inputs tolerate up to 5.5 V regardless of VCC level, enabling safe connection to 5 V signal sources without damage or level-shifting circuitry. This is overvoltage tolerance, not 5 V supply operation.
Can 1DIR and 2DIR be tied together for unified 16-bit direction control?
Yes - tying 1DIR and 2DIR together configures the device as a single 16-bit transceiver. Both 8-bit sections retain independent OE control (1OE/2OE), allowing selective 3-state control of either half-bus while maintaining synchronized directionality.
How does the bus-hold circuit behave when an input exceeds VCC?
Per datasheet Section 9 footnote [2], the bus-hold circuit disables automatically when VI > VCC, permitting 5.5 V input signals without conflict. In that state, the pin behaves as a standard CMOS input with leakage-limited DC behavior - no bus-hold contention occurs.
Is thermal derating required for continuous operation at +125 °C?
Yes - for the TSSOP48 (SOT362-1) package, total power dissipation derates linearly at 12.2 mW/K above +109 °C. At +125 °C, Ptot must be limited to ≤420 mW (500 mW − (12.2 × 16)) to ensure safe junction temperature - verify against actual switching activity and ambient conditions.
