Product details
Overview
74LVC162245ADL,118 from Nexperia is a 16-bit dual 8-bit bidirectional transceiver with integrated 30 Ω series termination resistors, 3-state outputs, and 5 V tolerant I/O. It operates from 1.2 V to 3.6 V supply, supports mixed-voltage translation between 3.3 V and 5 V systems, and features independent direction (1DIR/2DIR) and output enable (1OE/2OE) controls per 8-bit port. Used in high-speed parallel bus interfaces such as memory expansion, FPGA-to-ASIC data routing, and industrial backplane interconnects.
For engineers reviewing the 74LVC162245ADL,118 datasheet, 74LVC162245ADL,118 pinout, 74LVC162245ADL,118 application, or 74LVC162245ADL,118 equivalent, this device delivers deterministic bidirectional data flow control, IOFF-enabled partial power-down safety, Schmitt-trigger noise immunity, and bus hold (on LVCH variant) - critical for stable operation in noisy industrial and embedded computing environments.
Technical Context
This transceiver implements two independent 8-bit bidirectional data paths, each with dedicated DIR and OE inputs enabling granular control of data direction and output state. Its CMOS architecture supports rail-to-rail input thresholds with Schmitt-trigger hysteresis (≥0.3 V typical), ensuring robustness against slow-rising signals and EMI-induced glitches on PCB traces.
The integrated 30 Ω series termination resistors are placed at each I/O pin, reducing signal reflections and overshoot in high-speed parallel buses without requiring external discrete resistors. The IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V - a requirement for hot-swap and partial-power-down system architectures.
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. |
| I/O Voltage Tolerance | 5.5 V max - allows safe connection to 5 V peripherals without level shifters in mixed-voltage systems. |
| Propagation Delay (tpd) | 1.0 ns to 8.5 ns - supports >100 MHz bus clocking with predictable timing margins across voltage/temperature. |
| Termination Resistance | 30 Ω series per I/O - matches typical PCB trace impedance to suppress ringing on 50–75 Ω routed buses. |
| IOFF Leakage Current | ±10 μA max at VCC = 0 V - prevents damaging back-current during live insertion or staged power sequencing. |
| Bus Hold (LVCH only) | IBHL = 10 μA to 75 μA - maintains valid logic state on floating data inputs, eliminating need for external pull-ups. |
| ESD Rating | HBM >2000 V, CDM >1000 V - meets industrial-grade robustness requirements without additional protection circuitry. |
Pinout & Package
TSSOP48 package (SOT362-1): plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm pitch. Pin 1 index marked; lead finish: matte tin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Active-HIGH signal selecting data flow direction (A→B or B→A) per 8-bit port; determines driver source. |
| 1OE, 2OE | Output enable input | Active-LOW control disabling all 8 outputs in respective port to high-impedance state for bus sharing. |
| 1A0–1A7, 2A0–2A7 | Data I/O port A | First 8 bidirectional data lines; connected to local controller or master-side bus segment. |
| 1B0–1B7, 2B0–2B7 | Data I/O port B | Second 8 bidirectional data lines; connected to peripheral, memory, or slave-side bus segment. |
| VCC | Power supply | Single supply pin for core logic; four pins (7, 18, 31, 42) minimize IR drop and improve noise immunity. |
| GND | Ground reference | Eight ground pins (4, 10, 15, 21, 28, 34, 39, 45) reduce ground bounce and enhance signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 8-bit ports | Enables concurrent bidirectional transfers on separate buses - e.g., CPU data bus ↔ SRAM + FPGA configuration bus ↔ peripheral register bank. |
| Integrated 30 Ω series termination | Eliminates 32 external resistors in 16-bit interface, reducing BOM count, layout area, and impedance mismatch risk. |
| IOFF partial power-down | Guarantees zero back-current when VCC is off, satisfying IEC 61000-4-2 hot-swap and multi-rail sequencing requirements. |
| Schmitt-trigger inputs | Provides ≥0.3 V hysteresis, allowing reliable operation with slow-edge clocks or long unterminated traces up to 15 cm. |
| 5.5 V tolerant I/O | Permits direct connection to legacy 5 V logic without external translators - simplifies migration from older 5 V designs. |
Applications
| Industrial PLC Backplane Interface | FPGA-to-Memory Data Bridge |

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 |
|---|---|---|---|
| SN74LVC162245DGGR | TI part in same TSSOP48 package; identical 30 Ω termination, 1.2–3.6 V range, and 5 V tolerance; lacks bus hold. | No bus hold circuit - requires external pull-ups on unused inputs in floating-bus scenarios. | Select when sourcing from TI distribution channels or when bus hold is not required and cross-manufacturer qualification is approved. |
| 74LVCH162245ADL,118 | Nexperia variant with bus hold on all data inputs; otherwise identical pinout, timing, and electrical specs. | Enables true no-pull-up operation on unconnected data lines - reduces component count in space-constrained designs. | Prefer for new designs requiring guaranteed input state retention without external components; validated drop-in replacement except for bus hold activation. |
Compared with SN74LVC162245DGGR, the 74LVC162245ADL,118 offers identical timing and voltage specs but no bus hold; compared with 74LVCH162245ADL,118, it trades bus hold capability for marginally lower static current and broader qualification history in non-bus-hold applications.

FAQ
What is the maximum operating temperature range for 74LVC162245ADL,118?
The 74LVC162245ADL,118 is fully specified from −40 °C to +125 °C ambient temperature. This extended range is validated across all electrical parameters including propagation delay, output drive strength, and IOFF leakage, making it suitable for under-hood industrial enclosures and high-density compute modules without derating.
Does 74LVC162245ADL,118 support hot-swap operation?
Yes - its IOFF circuitry actively disables outputs when VCC = 0 V, limiting back-current to ±10 μA maximum. This satisfies IEC 61000-4-2 hot-swap requirements and enables safe insertion/removal in powered-backplane systems without disrupting other connected devices.
Can this transceiver be used as two independent 8-bit devices?
Yes - the device contains two electrically isolated 8-bit sections (Ports 1 and 2), each with dedicated DIR and OE inputs. Pins 1DIR/1OE control bits 1A0–1A7 ↔ 1B0–1B7; 2DIR/2OE control 2A0–2A7 ↔ 2B0–2B7, enabling simultaneous but independent bidirectional transfers.
Is external termination required when using the integrated 30 Ω resistors?
No - the 30 Ω series resistors are placed directly at each I/O pin and are designed to match typical PCB trace impedances (50–75 Ω). External termination is unnecessary unless system-level simulations indicate residual reflection due to complex stub topologies or >20 cm trace lengths.
